Analysis on the design of automation system for continuous press line

Analysis on the design of automation system for continuous press line
The new energy automobile industry has experienced considerable development in recent years, and new forces in vehicle manufacturing have continued to emerge. The Ideal Automobile Jiangsu ECG project is the company’s first production base and an important benchmark project for Internet vehicle manufacturing. In the first phase of the project, an automated stamping line is planned for the stamping workshop to provide the factory with body panels and large structural parts. The press line consists of 5 Jinfeng presses (2400t+1200t+1000t×3), and the automation system is provided by Shanghai ABB Engineering Co., Ltd. The production line is a continuous stamping line, which requires the production of aluminum and steel stamping parts. During production, it does not stop at the top dead center, and the robot and the press slide are positioned correspondingly and run synchronously.
The stamping line automation system consists of a destacking trolley, automatic splitting device, automatic detection device for material height/end material/double material, sheet material conveying/transition/line end conveyor belt, washing machine, oiling machine, centering device, robot and grasping Take the structure (end picker), control system and other components. Through this project, this article briefly describes the requirements of the continuous press line for the press, and analyzes the problems that need to be considered in the planning and design of some automation equipment.
Requirements for the press
As the first continuous stamping line in China that uses robots for loading and unloading, in addition to increasing the power of the main motor to meet the stamping energy requirements at low speeds, the press also needs to meet the following requirements.
⑴For the press with a work surface of 5000mm×2600mm, in order to provide enough space for the loading and unloading robot to pick and place parts, the stroke of the multi-link press at the beginning of the line is required to be ≥1400mm, and the stroke of the rest of the press is ≥1200mm.
⑵The press needs to increase the Simotion synchronization controller. The synchronous controller needs to keep the operating speed of the press and the phase difference between the presses constant, and the synchronization accuracy is controlled within ±5 degrees. The running speed of the entire line and the phase difference between the presses are adjustable, which are set by the automatic loading and unloading equipment .
(3) The press synchronization controller Simotion communicates with the automation complete line controller in real time through Profinet to achieve the following data transmission and format requirements. Simotion sends the virtual axis angle and speed to the automation controller, as well as the real-time angle and speed of the press. The speed signal sent by Simotion to the automation controller must be accurate to three decimal places, and the position signal of the press sent by Simotion to the ABB system must be accurate to One digit after the decimal point, Simotion also receives the data sent by the automation controller.
⑷ During an emergency stop, the press slider will have a certain braking distance. In order to avoid collision between the robot and the press slider, a certain safety distance must be left between the robot and the press slider. In order to increase the speed of the entire line, it is necessary to minimize the safety margin between the loading and unloading robot and the press slider. The general requirements for the brake angle of the press are shown in Table 1.
⑸The PLC of the press communicates with the complete line controller of the automation through Profinet (the same way as the intermittent line communication, the exchange of information is increased).
⑹Automation equipment needs to separately obtain the position information of the press slider, so the press needs to reserve a slider position encoder output shaft for automatic installation of the encoder.
Table 1 Braking angle requirements of the press
⑺ The press needs to have two production modes, intermittent and continuous, and easy to switch.
Automatic splitting system
The automatic splitting system (Figure 1) is composed of two elevating destacking trolleys and an automatic splitting device, which cooperate with the destacking robot to automatically call when stacking materials are switched one by one.
⑷The destacking trolley is equipped with a final material detection device on the table. When the pallet is empty, the robot automatically turns to another destacking trolley for destacking. At this time, the system sends out a sound and light alarm to remind the operator to replace the material. The operator presses the button to notify the PLC, and the destacking trolley automatically moves out of the work area to the designated loading position. The operator unloads the empty pallet and loads the pallet with sheets. When the destacking trolley passes through the grating, the grating fails.
⑸ Each destacking station is equipped with a set of stacking material splitting device (Figure 2), which is separately placed on the feeding belt conveyor and sent to the press for stamping.
⑴The destacking trolley of this project needs to meet the production of the largest sheet material, the table size is 4500mm×2400mm, and the load is 12t. Two destacking trolleys are respectively arranged on two parallel tracks, driven by a motor, and the speed is controlled by a frequency converter, and move between the loading station and the destacking station. Two trolleys work alternately. One trolley will automatically return to the loading station after destacking, and then back to the destacking station after manual loading. The destacking trolley must be equipped with a stop limit switch in place to prevent the worktable from moving when it is in place.
⑵The stacking trolley is equipped with a stacking lifting mechanism, which adopts a scissor support structure. The height of the stack on the trolley is detected by the photoelectric sensor. During the destacking process, when the sensor senses that the height of the stack is reduced, the lifting mechanism automatically raises the stack to the working height of the stack.
⑶ The platform of the destacking trolley needs to be equipped with a positioning device. The positioning device can be quickly removed and installed in other positions. The positioning device and positioning hole will be designed according to the specifications of all the racks of the production line to adapt to the positioning of all pallets. In addition, for stacks without pallets, the destacking trolley is equipped with a laser-assisted positioning device. For each different part, the system will save the laser positioning parameters, and the layout is the first 8 and the rear 8, and the splitting device is installed on the guide rail. The whole is fixed on the ground frame and driven by their respective cylinders. When feeding, the splitting head returns to the moving range of the destacking trolley, and will not interfere with the moving destacking trolley. When the destacking trolley completes loading and reaches the destacking position, the cylinder drives the magnetic splitting head to move toward the stack until it is close to the stack.
Figure 1 Automatic splitting system
Figure 2 Stacking and splitting device
⑹The splitting head can automatically adjust the angle to fit the stack material according to the shape of the sheet, and the angle adjustment range is 0°~30°. For ferromagnetic sheets, according to the principle of magnetic homogeneity repulsion, strong magnets are used for splitting. The strong magnets are installed inside the splitting device and have the function of pneumatic separation; for non-ferromagnetic sheets (such as aluminum plates, 304 stainless steel, etc.), use Air knife blowing and splitting method. Air knives are installed on both sides of the splitting head. When using air knife splitting, there is a greater demand for air pressure and flow. Pressure boosting equipment and air storage devices are required. Generally, the air pressure is ≥0.8MPa, The capacity of the gas storage device needs to be calculated based on the number of air knives, working rhythm, and blowing time. For example, in this project, the calculation result requires a gas storage tank capacity of 1.5m3. The specific parameters are shown in Table 2.
Table 2 Calculation of gas tank capacity
Destacking end picker
The tool used by the depalletizing robot to grab the sheet is the depalletizing end picker. The traditional press line depalletizing robots are only equipped with a set of universal depalletizing end pickers. The product blanks of this project are complex and diverse, and one set of end pickers is difficult. Meet the production of all products.
⑴In the design of the scheme, 3 sets of destacking end pickers are adopted, which are connected to the robot through a quick change device (Figure 3), and the end pickers are hung on the steel structure around the robot when not in use. When selecting the quick-change device, the load must be calculated. The heaviest sheet material of this project is 40kg, the destacking end picker is 50kg, and the quick-change device of model SWS-110 is selected, and the maximum load is 150kg.
Figure 3 Quick change device
⑵Equipment (depalletizing trolley, waste box, feeding belt conveyor) is arranged on the front, rear, left, and right sides of the destacking robot. In terms of the spatial arrangement of the automatic end picker replacement (ATC) bracket, the ATC bracket is considered in this design In the air, it is installed on a closed steel structure of the entire line. This design meets the needs of ATC and saves space, as shown in Figure 4.
Figure 4 ATC layout of the depalletizing robot
⑶In order to ensure that the 3 sets of end pickers can cover the production of all products, each suction cup of the end picker needs to be controlled separately, and each end picker is equipped with a valve island to control a suction cup. Choose the appropriate one according to the shape of the product during debugging. The end picker and the corresponding suction cup are stored in the product plan. In the later production switch, you only need to enter the product number to be produced, and the system will send the end picker and suction cup selection information to the robot according to the plan. The robot will automatically grab the end picker of the next product, and the end picker valve island will automatically follow the plan. Select the suction cup to be used. This design expands the product range of the production line and makes it easier to switch in later production.

The development trend of high-speed precision press

The development trend of high-speed precision press
⑴High speed.
The continuous increase in the number of strokes of high-speed presses has greatly improved production efficiency and reduced costs. Benefiting from the strong market demand for standardized, serialized, and batch-oriented functional stamping parts, the thickness of stamping parts is gradually reduced, and the required stamping tonnage is gradually reduced, which creates conditions for high-speed presses to increase the number of strokes. In addition, the development of high-speed precision stamping dies, especially multi-station high-precision progressive dies and automated peripheral equipment, has also created conditions for high-speed presses to increase the number of strokes. From the development history of high-speed presses, as the number of strokes increases by leaps and bounds, its nominal force and stroke show a decreasing trend.
⑵High rigidity and high precision.
Hard alloy molds are mostly used on high-speed presses, and the relative displacement of the concave and convex molds in the horizontal plane must be reduced to a minimum. The high-speed presses are required to have a certain level of rigidity. Due to the “reverse load” of the high-speed press, it is required to further increase its vertical rigidity. Usually adopt reasonable structural design and increase the design margin (increase the size of parts such as crankshaft, pin or ball joint) to ensure it.
High precision refers to high static geometric accuracy and dynamic accuracy (bottom dead center accuracy). The static geometric accuracy is related to the manufacturing level of the high-speed press, and the dynamic accuracy is achieved by adopting temperature control and bottom dead center dynamic compensation mechanism. In terms of static geometric accuracy, the Japanese Industrial Standards Super Precision Standard (JIS B 6402:1997) is basically the minimum standard, and the internal control standards of foreign companies have been greatly compressed on this basis.
⑶ The upper transmission is dominant.
The moving method of uploading has the advantages of lighter weight of moving parts, good layout, convenient maintenance, etc. It has become the mainstream method of high-speed presses and is widely adopted by domestic and foreign manufacturers. It is carried out in the aspects of transmission mechanism, guiding method, and dynamic balance mechanism. A lot of innovation. High-speed presses with lower drive mode only occupy a place in certain areas.
⑷ Closed structure will dominate.
With the further improvement of the accuracy of hedging products, the use of closed structures is an inevitable trend. On the one hand, the closed structure has a large space for the installation of dynamic balancing devices, which is beneficial to increase the number of strokes (super high-speed presses from 3000 to 4000 spm are closed structures), thereby improving production efficiency; on the other hand, the closed structure has good rigidity, It can improve the precision of punching products and the service life of molds. In addition, the use of a closed structure can increase the width of the worktable and facilitate the use of multi-station progressive dies.
⑸ The dual-point structure gradually develops towards multiple points.
Closed high-speed presses are mostly of double-point structure. With the increase of stamping die stations and the size of stamping products, it is required to widen the working table and increase the punching force. The use of double-point structure requires further enlargement of the slider and guide Stiffness. Therefore, many companies adopt a three-point or four-point structure, and the auxiliary guide adopts a cylindrical type, which can not only reduce the weight of the slider, but also increase the number of strokes.
⑹Using new materials.
As the accuracy requirements for high-speed presses continue to increase, new materials are continuously being used. The main purpose is to reduce the weight of moving parts, reduce the impact of temperature changes on the bottom dead center, and improve the load-carrying capacity under the premise of ensuring rigidity. The new materials used mainly include:
1) Low density materials. Some of the high-speed presses of American OAK Company use super-hard aluminum alloy for the slider, which reduces the weight by 60%; the 100kN, 4000spm ultra-high-speed press of Nidec Kyori Co., Ltd. uses ceramic-aluminum alloy composite material for the slider. The inertial force of the moving parts of the slider is reduced by 40%, reducing the impact of changes in the number of work on the accuracy of the bottom dead center.
2) Low expansion coefficient materials. The U-series high-speed press from ISIS, Japan, the main drive components and couplings are all alloy castings with low thermal expansion coefficient Nobinate-5 (Ni content 36%, Co content 6%), and its thermal expansion coefficient is only 1/4 of steel ~1/3, the hardness is equivalent to FCD45-50. In addition, some companies use Invar alloy with a smaller coefficient of linear expansion as the sliding bearing material to reduce the impact of thermal deformation on the accuracy of the bottom dead center.
3) Other special materials. With the increase in the number of strokes of high-speed presses, special materials are gradually used in the sliding support or guiding parts. For example, babbitt alloy with better friction performance is used for sliding friction parts; high-strength brass or beryllium bronze is used for parts bearing large impact loads such as bowls.
⑺Using high-precision bearings.
Rolling bearings are in line contact when subjected to impact loads and have poor rigidity. Especially when they are under heavy load, the bottom dead center accuracy will be unstable, so they are mostly used for medium and small tonnage high-speed presses. The development trend of rolling bearings is to further improve accuracy and focus on the perfect combination with high-speed presses.
The sliding bearing is surface contact with high rigidity, which is beneficial to the stability of the bottom dead center accuracy. With the continuous improvement of the overall manufacturing accuracy of high-speed presses, and the use of oil temperature control and large-flow lubrication systems, the heating of sliding bearings has been effectively resolved, and they have been gradually reused in high-speed and ultra-high-speed presses. The development trend of sliding bearings is to apply new materials and further improve manufacturing accuracy.
Japan AIDA company uses composite bearings (rolling bearings + sliding bearings). When stamping, the sliding bearings work and have high rigidity; when not stamping, the rolling bearings work and the friction is significantly reduced, which is beneficial to high-speed operation.
⑻Highly integrated.
The efficiency and accuracy of punching products are not only related to the high-speed precision press itself, but also related to its supporting peripheral equipment and molds. Many manufacturers have begun to pay attention to peripheral equipment and molds and incorporate them into their business scope. In addition, the use environment is also taken into consideration. On the one hand, it is the problem of stamping noise protection, on the other hand, it is the impact on accuracy. Moreover, some manufacturers have adopted the soundproof room as a standard configuration, such as the soundproof room of the MXM series high-speed press of YAMADA DOBBY of Japan.
This integration is also reflected in the control system, which makes the high-speed press present certain characteristics of metal cutting machine tools. For example, the handwheel is used to precisely adjust the height of the mold, the windows-based visual operating system is used for the input and storage of stamping parameters, the online monitoring system (such as the BRANKAMP system) is used to monitor the operating parameters of the stamping line in real time, and the Internet technology is used for online fault monitoring And disposal etc.
⑼ Application of servo drive technology.
The application of servo drives in stamping equipment can achieve high process flexibility while simplifying the transmission system. The high-speed precision press reflects a high degree of “rigidity”. With the development of servo technology and the improvement of users’ stamping process, it will realize the “combination of rigidity and flexibility”, that is, the application of servo drive technology to the field of high-speed precision presses. For example, the Fit-3 type high-speed servo press developed by Japan’s YAMADA DOBBY company is driven by a servo motor without clutch and brake.

Overview of High Speed ​​Precision Press
High-speed precision presses are mainly used for high-speed stamping of precision parts, which require high precision and rigidity. Regarding the definition of high-speed precision presses, there is currently no unified standard. Its speed is related to many factors, mainly the stroke of the slider, the nominal force, the size of the stamping parts, and the structure of the punch, so it is difficult to use a simple number as the dividing standard . The high-speed precision press mentioned in this article refers to a mechanical press that is used for stamping precision small parts within a stroke of 50mm.
Classification of high-speed precision presses
⑴Press speed. Table 1 shows the division of small high-speed presses with a nominal force of 600kN or less by some companies, and the stroke of the slider is not considered in the division.
⑵According to the layout of the transmission system, it is divided into upper transmission and lower/bottom transmission structure.
⑶According to the fuselage type, it is divided into open, closed and four-post fuselage.
⑷According to the number of force points, it is divided into single point, double point, three point and four point.
⑸According to the form of driving mechanism, it is divided into sine, crank slider, multi-link and double ball head structure.
⑹According to the number of drive systems. There is generally a set of drive systems in the transmission system of ordinary high-speed presses. With the development of high-speed presses to large tonnage and wide tabletops, a set of drive systems cannot meet the requirements. Japan’s Aitian MSP series press (Figure 1) uses two drive systems, which are arranged at both ends of the crankshaft, eliminating the synchronization error caused by the crankshaft deflection angle at the moment of starting.
Table 1 Classification of high-speed presses below 600kN
Figure 1 MSP series press
⑺ According to the form of the drive motor, it is divided into conventional motor drive and servo motor drive.
⑻According to the stamping parts, it can be divided into stamping transformer/micromotor/industrial motor core, stamping lead frame, stamping easy-open lid, stamping air conditioning fin, stamping chain, stamping connector high-speed press, and other stamping metal and non-metal small parts Punch etc.
The development of high-speed precision press
Development overview of domestic high-speed precision presses
⑴ Closed high-speed precision press.
1) my country’s closed high-speed precision presses started from the original “60-ton closed high-speed precision press development” project undertaken by the Jinan Foundry and Forging Institute during the “Sixth Five-Year Plan” period. Jointly developed my country’s first high-speed precision press J75G-60 (nominal force 600kN, stroke rate is 400 times/minute), and then developed a high-speed precision press with nominal force 300kN and stroke rate of 600 times/minute.
2) In the mid-1980s, Qiqihar Second Machine Tool Plant introduced the design and manufacturing technology of the SA series of high-speed precision presses of 800kN, 1 250kN and 2000kN from the German Schuler Company; Shanghai Second Forging Machine Tool Plant from Germany Haolic-Ross Company introduced two specifications of high-speed precision presses, RVD32-540 and RVD63-800, and developed three products of 1000kN, 1250kN and 2000kN on this basis.
3) In the same period, Xu Duan Group independently developed the JF75G-100 closed double-point high-speed press. When the slider stroke is 30mm, the maximum stroke frequency can reach 300 times per minute; through the technology of the JF75G closed double-point high-speed precision press In 2006, we completed the research and development of the first 3000kN closed double-point high-speed press in China; from 2012 to 2014, the existing JF75G series presses were systematically upgraded, and 500 times were achieved on the JF75G-200C model. Minute no-load punching speed and 420 times/min punching speed. In addition, in 2012, Xu Duan successfully developed the JL75G-60 600kN multi-link high-speed ultra-precision press.
4) Yang Forging Group started a little later, and has now developed the J76 series of presses (800kN ~7500kN), of which 800kN~3000kN is a six-round guide column structure, and the rest is a four-corner and eight-sided guide rail structure; 5500kN (nominal force stroke 1.6mm) The closed double-point high-speed precision press has a maximum stroke frequency of 230 strokes per minute when the slider stroke is 40mm, which is the first in China.
5) Ningbo Jingda’s technology is similar to American OAK, adopting sine mechanism. Developed GC series models for stamping air-conditioning fins and GD series models for stamping motor stator and rotor cores. The 3000kN closed double-point high-speed precision wide-table press has the highest stroke times when the slider stroke is 30mm. Up to 400 times per minute.
6) Ningbo Minsk and Zhejiang Shuaifeng have successively developed small closed high-speed precision presses (multi-link type). Ningbo Minsk’s Super-30 300kN high-speed press has a maximum stroke of 25mm when the slide stroke is 25mm. 1050 times/minute.
7) “High-end CNC machine tools and basic manufacturing equipment” science and technology major project implementation management office successively issued major scientific and technological projects in March 2009, February 2010, April 2011 and April 2012 to support high-speed precision presses The research and development of micro motors, new energy vehicles, integrated compressors and other products provide support. At the same time, the GB/T 29548-2013 “Closed Type High Speed ​​Precision Press Accuracy” standard was promulgated to better promote the healthy development of high speed precision presses.
⑵Open high-speed precision press.
The open-type high-speed precision press presents two forms in the guiding structure. The first is a three-circle guide pillar structure, which is mainly used for high-speed stamping of precision microelectronic parts. Except for Xu Duan Group, other companies generally use auxiliary guide pillars. Fixed three-round guide column structure. Yangli Group’s SHC-25 250kN open type ultra-high-speed press has reached a high speed of 1000 times per minute when the slide stroke is 20mm.
The second type is the traditional V-shaped guide or rectangular guide, which has high load-bearing rigidity but lower speed. It is mostly used for high-speed stamping of small micro-motor stators and rotors, E/I cores and other parts. It can also be used for stamping of some air-conditioning fins. The slider stroke is slightly longer and the speed is lower. For example, in the JL21 series of open high-speed presses for air-conditioning fins of Yangdu Group, the 450kN press has a maximum stroke of 250 strokes/minute when the slider stroke is 40mm, and the 800kN press has 120 strokes/minute.

Many large South Korean auto parts manufacturers announced the suspension of production

Many large South Korean auto parts manufacturers announced the suspension of production
As the epidemic continues for a long time, the operating conditions of the Korean auto parts industry, which is increasingly tight, have become increasingly difficult. A few days ago, many large South Korean auto parts manufacturers announced the suspension of production, which directly affected the normal production of Korean automakers. For the relevant situation, I will immediately connect with the special reporter Xuan Lina of the financial channel in Seoul. What is the current operating status of the Korean auto parts industry? What impact will it have on the Korean automobile industry chain?
Finance Channel Special Correspondent Xuan Lina: Last week, the South Korean company of Gates, a global automotive belt manufacturer, announced that it would close its Korean plant and withdraw from the Korean market this month. Earlier, a Korean company that produced fuse boxes and seat accessories for Hyundai Motor’s Santa Fe and other models also announced that it would stop production.
It is understood that there are not many parts and components related to Hyundai’s inventory. Hyundai is currently negotiating with this company to restart production, and finally assemble the affected models after the relevant parts are in place.
As the epidemic continues to spread, problems have appeared in some links in the industrial chain. Almost all large-scale car companies in South Korea and the world have experienced a decline in production due to large-scale shutdowns, which has reduced the demand for parts and components in the market and made Korean auto parts Enterprises are caught in the dilemma of both domestic and overseas orders diving.
In May of this year, South Korea’s auto exports fell 54% year-on-year, and auto parts exports dropped by 66.7% year-on-year. According to data from the Korea Automobile Industry Federation, the operating rate of large auto parts companies that directly cooperate with vehicle manufacturers was only 60% in May, and the operating rate of small and medium-sized parts companies that accepted orders from large auto parts companies dropped to 30. %-40%.
In the first quarter of this year, among the more than 80 listed auto parts companies in South Korea, about 80% of the companies’ performance deteriorated, and nearly half of the companies have already experienced deficits. Although the South Korean government has issued support policies several times recently, and has provided 2 trillion won, or about 11.8 billion yuan, of special low-interest loans to parts and components companies, it is tantamount to a drop in the bucket for companies.
Under the epidemic, the difficulties of automakers have led to the deterioration of the operations of Korean parts and components companies. The current shutdown of some parts and components companies has in turn affected the production of Korean automakers, forming a vicious circle in the automotive industry chain. As the industry is looking forward to a recovery in global automobile sales, how can Korean parts companies persist in the industry’s recovery? How will the government’s next support measures be carried out? We will continue to pay attention to relevant developments.

One engine offline in 45 seconds! Great Wall series core parts products are here

One engine offline in 45 seconds! Great Wall series core parts products are here
“157 processes, one engine off the assembly line in 45 seconds!” On the morning of June 30, in the Hive Yichuang Yangzhong Industrial Park, the production line was fully fired and the employees were full of energy. On the same day, the first engine of Hive Power System and the signing ceremony of the project were held. After more than 400 days of hard work, the power project of Great Wall Motor Hive Yichuang Yangzhong Industrial Park was officially put into production.
The Hive Yichuang Yangzhong Industrial Park is one of the major projects in Jiangsu Province introduced by Jiangsu Yangzhong. In July 2018, Great Wall Motors and Yangzhong joined hands. The Hive Yichuang Automobile’s core parts project became an important part of Great Wall Motor’s layout in the “Yangtze River Era” ; In February 2019, the engine project of Honeycomb Power (Jiangsu) Co., Ltd. broke ground, starting from the flat ground to the first product launch. Honeycomb Yichuang once again set a “Hive” speed in promoting the industrialization of core technology products.
It is reported that the engine off the assembly line this time is an EB engine with a planned production capacity of 250,000 units/year. From July to December 2020, the estimated production capacity will reach 80,000 units, with an output value of nearly 1 billion yuan.
In addition to the engine project that has been put into production, the construction of other projects in the industrial park is also proceeding in an orderly manner. The transmission project and the electric drive project are expected to be put into operation in October 2020, and the intelligent steering and die-casting project is expected to be put into operation in March 2021. It will form a production capacity of one million units, and will become one of the important production bases of China’s automotive key parts and components, providing assistance for the optimization and upgrading of the global automotive supply chain system.
The establishment of the Hive Yichuang Yangzhong Industrial Park has successively attracted many high-end auto parts projects in Yangzhong, further extending the city’s auto parts industry chain. At the event of the day, two industrial chain supporting projects with an annual output of 100,000 units of EG01H/EG08B engine assembly project and high-end tool project with a single investment of over 100 million yuan were signed. It is expected that the annual revenue will reach nearly 1 billion yuan after the production is completed. Taxes are nearly 30 million yuan.

Volkswagen announced the cancellation of Turkey’s plant construction plan

Volkswagen announced the cancellation of Turkey’s plant construction plan
On July 1, according to “European Automotive News”, Volkswagen has decided not to build a multi-brand plant in Turkey because of the plummet of car sales under the influence of the coronavirus, making it difficult for its existing plants to operate at full capacity.
As early as November 2018, Volkswagen announced plans to build a new plant in Eastern Europe to produce Volkswagen models such as the Skoda Karoq and SEAT Ateca.
After multiple evaluations, Volkswagen finally chose Manisa, located 40 kilometers northeast of Izmir, on the west coast of Turkey, as the location of the factory. It is reported that the company originally planned to start production in 2022, with an annual output of up to 300,000 units and employing 4,000 workers.
Once completed, the Turkish plant will greatly alleviate the production capacity restrictions of Skoda’s local Czech plant and enable Volkswagen to release its production capacity at the Emden plant in Germany, which is used to produce Passat, and thus transform the production of electric vehicles.
However, in October last year, Volkswagen postponed its plan to build a factory in Turkey for the first time due to fears that the international community would condemn the Turkish military actions. This move has also attracted strong interest from the three Balkan countries of Bulgaria, Romania and Serbia, and they are vying to introduce this project worth 1.3 billion euros (about 10.2 billion yuan).
Although the decision was postponed, Volkswagen emphasized that it has no plans to find alternative destinations for the new factory.
According to sources, the Turkish plant will be Volkswagen’s 133rd plant in the world, but under the epidemic, this plant will only become the automaker’s excess capacity.
In this regard, Volkswagen also stated that the decision to stop building the factory was due to the decline in global sales caused by the new coronavirus epidemic.
Data show that as the global market continues to be affected by the pandemic, the Volkswagen Group sold a total of 609,000 vehicles worldwide in May, a year-on-year decrease of 34%. In the first five months of this year, the Volkswagen Group’s cumulative global sales reached 3.09 million vehicles, a year-on-year decline of 30%.
Specifically, in Western Europe, Volkswagen Group’s sales in May fell 57% year-on-year; in Central and Eastern Europe, it fell by 51%; and in North America and South America, it also plummeted by 39% and 69%.
In contrast, in the Chinese market where the epidemic is basically under effective control, Volkswagen Group’s sales in China rebounded 5.7% in May. At the same time, as of the beginning of June this year, the production capacity of all Volkswagen Group factories in China has been close to 100%.
According to Volkswagen CEO Herbert Diess, “demand has fallen to the bottom” because of the new crown epidemic. As a result, Volkswagen lowered its liquidity. The current weekly liquidity is less than 2 billion euros, compared with 21.3 billion euros at the end of the year.
“Volkswagen started planning to build a plant when the economic conditions (especially in Eastern Europe and the Middle East market) were generally improving.” The company said in an e-mail statement to “European Automotive News”, “But as far as it is concerned, , The situation is not as expected.”
It is reported that in 2018, Volkswagen’s core strategic goal is to increase global production and sales to 10 million vehicles, so building or expanding factories around the world has become a key content.
In fact, due to the sudden epidemic, many multinational auto companies have changed their original expansion strategies.
On May 14, Nissan Motor Co. plans to cut its global production capacity by about 20% from the current 7 million vehicles by 2022, including withdrawing from the Korean market by the end of 2020; in addition, BMW and Honda are also in the global scope. A large number of 6,000 and 3500 employees were laid off.

Because the restructuring plan exceeds expectations, Daimler will sell the French Smart factory

Because the restructuring plan exceeds expectations, Daimler will sell the French Smart factory
On July 6, Beijing time, according to a report on the European Automotive News website, Daimler will seek to sell its plant in Hambach, France. The automaker is undergoing a deeper reorganization beyond expectations to overcome the new model. The impact of the coronavirus epidemic.
Daimler, which owns the Mercedes-Benz and Smart brands, has used derivatives of Smart electric and internal combustion engines at the Hambach plant. In 2017, the plant produced more than 80,000 vehicles.
The company said in a press release last Friday that this move will bring about a one-time negative impact on the second quarter results worth about 500 million euros.
Daimler CEO Kang Linsong pointed out in the press release: “The economic impact of the new crown pneumonia epidemic is creating new framework conditions. In this case, we are optimizing our global production network.”
It is worth mentioning that Smart production will be transferred from France to China. Previously, Daimler said last year that it would produce the next generation of Smart electric vehicles through a joint venture with Geely.
Just as the Hambach plant was being sold, the European automotive industry was facing a situation of overcapacity and a sharp drop in demand for new cars.
The plant was put into operation in 1997 and currently has approximately 1,600 employees. In 2018, Daimler stated that it would invest 500 million euros in Hambach to produce a compact electric vehicle under the new EQ electric sub-brand of Mercedes and a battery-powered derivative of Smart ForTwo.
Kang Linsong warned earlier last week that he would have to undergo a more painful reorganization due to the impact of the new coronavirus. He revealed that on top of the restructuring plan announced in November, he plans to “significantly” cut salaries, including the abolition of more than 10,000 positions.
