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.

In response to the trend of new energy vehicles in the second half of the year, Xu Haidong, deputy chief engineer of the China Automobile Association, said that with the improvement of the epidemic, many governments have issued policies to stimulate automobile consumption, especially the subsidy policy and preferential system for new energy vehicles. The car will gradually return to a stable state. In addition, the Gasgoo Research Institute predicts that the proportion of electrification in the passenger car market will increase to 10% in 2020.

In the post-epidemic era, how can the forging industry develop real “immunity”?

In the post-epidemic era, how can the forging industry develop real “immunity”?
After half a year of working together to fight the epidemic, the domestic epidemic has basically stabilized at this stage, and all walks of life are trying their best to “recover”. It seems that the impact of the epidemic is gradually digesting. However, we must realize that the epidemic brought to the forging industry not only the appearance of restricted business trips and delayed exhibitions. In the post-epidemic era, how should the forging industry develop its real “immunity”?
01Changes and Breakthrough
Grasp the changing points of the market and realize the breakthrough of industrial chain reconstruction
In the early stage of the epidemic, most of the industrial chains closely related to the forging industry encountered the risk of chain disconnection. Among them, the auto parts supply chain was particularly affected. After realizing the problem, companies responded quickly and continuously sought the industrial chain for six months. And the substitute of the supply chain, actively enhancing the resilience of its own industrial chain and supply chain.
The picture shows the visit to the 2019 Forging Automation and Information Conference
Although the import and export situation will still be affected by the epidemic in the short term, all sectors of society have noticed the importance of returning to manufacturing, especially basic manufacturing. In the foreseeable future, companies in the forging industry need to pay special attention to some market changes, such as product inspection and quarantine standards, and the balance between quality and industrial aesthetics.
02 Technology and Theory
Technology is still the key, and cross-study of basic theories must persist
It is not a day’s work that an enterprise can stand up in difficult times, or even rise and show strong competitiveness. Behind this is the development and integration of practical technology and basic theory, and the continuous improvement of its own core technology and craftsmanship. Innovation, the epidemic also reminded to a certain extent the necessity of keeping technical files in the forging industry.
The picture shows the visit to the 2019 Forging Automation and Information Conference
Looking at the development of the forging industry in recent years, it is not difficult to find that the process technology and equipment are somewhat slow. The reason is that on the one hand, it is related to the accuracy of the design and production details. On the other hand, the basic theory has not been special for many years. For innovation, in the future, companies can consider interdisciplinary research (such as electromechanical + information) to obtain new discoveries.
03Transformation and characteristics
Make good use of the “reverse method” to form a differentiated automation transformation
Different from the virtual economy such as finance, when it comes to innovation, the forging industry first thinks of technological innovation, but often ignores management innovation. In fact, good management innovation is a catalyst for technological innovation, and it will definitely promote technological progress. With a dedicated person to do special tasks, you can try to apply the “reverse method” commonly used in industry to corporate management to form a complete professional team.
The picture shows the site of the 2019 Forging Automation and Information Conference
The outbreak of this epidemic has accelerated the pace of automation transformation and upgrading. Efficient operation, stable production and high production are no longer the only pursuits of current outstanding companies. Differentiation and rationalization are upgraded together, and compound and professional talents are the guarantee. The key for forging companies to further their basic development.
04Experience and original intention
Seeking truth from facts and turning complexity into simplicity, original intention and enthusiasm are both important
What we can’t deny is that seeking truth from facts is still the mainstream ideology needed in this era, but as everyone’s habit of receiving information and learning methods gradually become concise and clear, how to simplify the complexity and directly hit the main points will also become a manifestation of corporate wisdom and charm. One way.
The picture shows the site of the 2019 Forging Automation and Information Conference
Compared with material, efforts driven by spirit will last longer. This is one of the reasons why we often say that we never forget our original intention. For the forging industry, experience is very important, but not necessarily effective. We need enthusiasm and passion to continuously adjust and change our inherent model with the changes in the general environment to better learn, understand, practice and catch up with the industry Change.
05Respect and win-win
Respect trustworthy competitors and build a true industrial culture confidence
The epidemic has made companies more cautious in exiting and entering the industry market, but it should be noted that competing for users is not the same as competing for orders. Instead of making a profit of about 20% to grab a mature product from others, it is better to focus on new products. Compete vigorously with each other, starting from technology and design cooperation.
The picture shows the site of the 2019 Forging Automation and Information Conference
The so-called high quality and low price, small profits but quick turnover are essentially contrary to the value price theory. Respecting trustworthy opponents in competition is a good choice for mutual benefit. Since the outbreak of the epidemic, more foreigners have begun to think about and study what the Chinese often call “win-win and self”. This time, the construction of a true industrial culture in our country has begun.
The wind rises at the end of Qingping, and the waves become between the waves. Over the past six months, the entire industry has become more aware that “hibernating” passive waiting cannot help everyone out of the cold winter. In this special period, can you be sensitive It is especially important for companies to capture new changes, new trends, and new opportunities in the industry.

Toyota launches stamping electroplating machine

Toyota launches stamping electroplating machine
According to foreign media reports, Toyota Motor Corporation has developed the world’s leading stamping electroplating technology. This technology uses a polymer membrane (solid electrolyte membrane) that allows metal ions to pass through the membrane and be electroplated only to the necessary area, just like a postage stamp.
In the manufacturing process of electronic parts, this technology can be used for electroplating to form copper, nickel and other metal plating layers on the substrate. Toyota also announced that it has entered into cooperation with Japan’s Emperor Technology Co., Ltd. and Japan’s Kanematsu Corporation to produce and sell new electroplating machines based on this new technology, thereby expanding its scope of use. These machines will be put into use on July 1.

Research on Flexible Manufacturing Technology of Commercial Vehicle Longitudinal Beam

Research on Flexible Manufacturing Technology of Commercial Vehicle Longitudinal Beam
Commercial vehicles have the characteristics of large load, high utilization rate and long average annual mileage. They are an important part of the automobile industry and play a pivotal role in the development of the national automobile economy. As the largest and most critical component in the field of commercial vehicles, the manufacturing level of commercial vehicle beams affects the service life, fuel economy, handling and safety of commercial vehicles.
The traditional longitudinal beam manufacturing mode is mainly based on stamping. The prominent problem is that the mold is frequently replaced during the production process, which causes a lot of production time to be wasted. At the same time, there are also insufficient flexible processing capabilities, long production preparation cycles, high mold investment costs, and longitudinal molds. Liang rebounds serious and other problems. With the intensification of market competition and the application of high-strength panels, customer needs are gradually showing the characteristics of customization, lightweight and individualization. Therefore, the development of flexible stringer manufacturing equipment and technology improves the intelligent level of production lines to meet the needs of large-scale While automating production, it can also take into account the small batch and multi-variety production mode, which has important promotion significance in the field of commercial vehicle chassis manufacturing.
Structural analysis of commercial vehicle longitudinal beams
According to the different capacity of commercial trucks, they can be divided into light, medium and heavy. Their frame structure characteristics are shown in Figure 1.
Light truck type longitudinal beams are mainly variable cross-sections. As shown in Figure 1(a), the sinking of the front section of the frame can greatly reduce the center of gravity of the vehicle, and the installation plane of the front suspension bracket of the cab will be about 10cm lower than that of the through beam. The height of the room above the ground is greatly reduced. The reduction in the height of the front and rear widths of the frame longitudinal beams makes the entire frame closer to the equal-strength beam structure, avoiding unnecessary steel waste in the parts of the front and rear sections of the frame that are less stressed, and it is also an effective measure to reduce weight.

Figure 2 Light truck longitudinal beam stamping line of a domestic vehicle manufacturer
The light truck type longitudinal beam has a cross-section width of 160-220mm, a length of 5-7m, and a material thickness of 4-6mm. The current mainstream manufacturing method of this type of stringer is still mainly stamping. As shown in Figure 2, a large press is used to complete the manufacturing process of the stringer with blanking punching dies and profiling dies. In order to meet the market demand of multiple varieties and small batches, large-scale press blanking and punching are gradually replaced by CNC flat punching and plasma cutting, thereby shortening the manufacturing cycle of the stringer and reducing the cost of molds.
Medium and heavy trucks gradually adopt the design idea of ​​constant cross-section longitudinal beams, as shown in Figure 1(b) and Figure 1(c). The cross-sectional width of the longitudinal beam is 220-360mm, the length is 5-12m, and the material thickness is 5-10mm. Some domestic automakers generally adopt the stamping process for production, which facilitates the organization of production and also reduces the investment costs of stamping equipment and molds to a certain extent.
However, with the continuous improvement of vehicle lightweight requirements, the yield strength of longitudinal beam steel plates is also getting higher and higher. The tonnage of ordinary presses can no longer provide sufficient punching and forming pressure, and the purchase of larger tonnage presses will bring Come higher manufacturing costs. In addition, during the stamping and forming process of high-strength steel plates, affected by the performance of the sheet metal, cracks are easily generated in the stamping deformation zone, which seriously affects the product quality.
Stringer flexible manufacturing system
This article takes the longitudinal beam production line of a domestic commercial vehicle manufacturer as an example to discuss the composition of the longitudinal beam flexible manufacturing system. At present, the cross-sectional shape of the longitudinal beams of commercial vehicle chassis is mostly “U”-shaped, with a maximum length of 12000mm, a maximum width of 360mm, a maximum thickness of 12mm, and a yield strength of 350-700MPa.
The flexible manufacturing process of the stringer includes rolling (coil feeding, uncoiling, leveling, head cutting, rolling forming, online inspection, correction, follow-up cutting) → marking → CNC punching → robotic plasma cutting → calibration Straight → shot blasting → beam bending → transport to the storage area. In order to improve the level of automation, each process equipment is integrated through the logistics on-line system to achieve the goal of less human production.
Flexible roll forming
The first sequence of the production line adopts flexible rolling type gradual forming, which can effectively avoid the problems of springback and deformation and cracking of the sheet during the stamping process. At the same time, the production efficiency is high and the labor intensity is low. The flexible rolling equipment can automatically drive the forming roll by the motor according to the changes of the longitudinal beam product parameters (such as material thickness, length, cross-sectional size, etc.) to adjust the corresponding parameters of the equipment without changing the roll. Before the new specifications of the longitudinal beams are put into production, there is no need to prepare additional molds, which shortens the production preparation cycle and simplifies the product development process. When the normal production parameters change, the adjustment time of the rolling equipment (Figure 3) parameters is less than 5 minutes, which is much shorter than the replacement time of the stamping die.

Longitudinal beam three-dimensional punching
The number of holes on the longitudinal beams is generally 200 to 500, distributed on the ventral surface and the wing surface. The level of flexibility of the production line is also reflected in the hole processing. In order to meet the three-dimensional flexible punching of stringers, five main machines and three-sided punching (Figure 4) are used to complete the hole punching process. When the longitudinal beam is on the feed conveyor raceway, the U-shaped opening is downward. The feed direction of the longitudinal beam is the X axis, the reference of the X axis is the front end face of the longitudinal beam wing surface, and the horizontal direction perpendicular to the X axis is the Y axis. The wing surface of the beam can be taken as the Y reference, and the axis perpendicular to the horizontal plane is The Z axis, the Z axis reference is the upper surface of the beam, as shown in Figure 5.
Figure 4 Three-dimensional punching equipment
Figure 5 Schematic diagram of the longitudinal beam coordinate system
The hole position tolerance of the punched parts: the position tolerance of the hole group is ±0.2mm/300mm, the tolerance of the hole center distance is ±0.5mm/12000 mm, and the tolerance of the hole edge distance is ±0.5mm. During the whole punching process, the CNC punching program is automatically switched, and the production efficiency is high.
Another three-dimensional processing technology for longitudinal beam holes is to use numerical control drilling equipment and special fixtures to form a drilling production line. The drilling equipment does not interfere with each other and can meet the needs of simultaneous drilling. Before drilling, you can first assemble the longitudinal beam and the inner reinforcement plate into an assembly. After fixing with a clamp, use the holes on the longitudinal beam as a guide and drill the holes on the inner reinforcement plate. This method can effectively ensure the longitudinal beam It is absolutely consistent with the aperture and position of the two parts of the reinforcing plate.
Robot 3D cutting
The robot plasma cutting is shown in Figure 6, and completes the cutting work of the front and rear ventral surface of the longitudinal beam, the airfoil surface, and the circular holes and special-shaped holes with a diameter greater than 60mm. During the cutting process, the system issues a feeding instruction → automatic transmission system feeding → feeding to the beam head cutting position → automatic pressing → cutting front shape (wing surface, ventral surface or oblong hole) → robot, pressing and grounding mechanism return to the original position → Feed the material to the beam tail cutting position→automatic pressing→cutting the shape of the rear end→releasing and discharging→the next cycle.
Figure 6 Robot plasma cutting
The flatness of the cutting surface should not exceed 1.2mm, the depth of the cut pattern should not exceed 210μm, and the cutting surface should be smooth and free of cutting edges. The size tolerance of cutting parts is ±1mm, and the tolerance of airfoil length cutting size is ±2mm.
CNC bending
The CNC bending production line is a special equipment designed and manufactured for the front width and rear narrow structure of the longitudinal beams of medium trucks and heavy trucks. Compared with the forming by stamping, this equipment solves the problem of flexibility required for production, so that only a small amount is needed. The adjustment can meet the forming needs of different longitudinal beams and inner reinforcing plates, as shown in Figure 7.
Figure 7 CNC bending production line
The production line can realize flexible bending actions of multi-variety, multi-angle longitudinal beams and inner reinforcing plates. There is no need to replace molds during the production process, with high degree of self-adaptation and high production efficiency. During the forming process, the wrinkling generated in the deformed area is significantly better than traditional mold forming, and it is widely used in the domestic commercial vehicle manufacturing field.
Intelligent marking and identification system for production line
In order to track the flow of the longitudinal beams between the various processes, the coding, identification, detection and control system of materials are generally used to realize the automatic collection and identification of logistics information. The marking and identification system is composed of a marking machine and a marking recognition device. It is used to mark and identify materials, and in the process of material circulation, the identification device is used to identify the markings printed on the materials, and the overall control software and each material The memory information of the management unit is compared to ensure accurate information transmission.
The production of the longitudinal beams of this project is mainly composed of flexible roll forming, three-dimensional punching, three-dimensional robotic cutting, CNC bending and other processes. The material management control system uses an intelligent marking machine to code each material from the rolling blanking. Marking and coding include QR code and digital code.
When each workpiece passes through various process equipment, the QR code on the workpiece is identified by the barcode reader installed on the device, and the identified workpiece information is fed back to the material control unit PLC, which not only verifies the workpiece logistics, but also It also tracks the processing process of the workpiece, and realizes real-time monitoring and tracking of the workpiece logistics. If the workpiece has quality problems in the downstream assembly process, the quality of the workpiece processing process can be traced.
Production line logistics control system
In order to fully balance the production cycle of the equipment in the various processes of marking, punching, cutting, and bending, increase the overall processing speed of the production line, and solve the contradiction of uneven work stations, the production line logistics control system (Figure 8) is configured, which is based on the production equipment The priority of the request, the processing capacity of the equipment, and the balanced production are used to schedule the operation plan at the process level and the equipment level. This kind of scheduling is based on limited capacity scheduling, and accurately calculates the start time, completion time, preparation time, queuing time and moving time of the process by considering the interleaving, overlap and parallel operations in production to ensure that it will be appropriate at the right time The materials are sent to the appropriate equipment and the overall productivity is increased by more than 50%.
