Volkswagen Group has once again taken significant steps to deepen its collaboration with China FAW Group. Dr. Wei Zhibo, Vice President of Volkswagen Group, Dr. Lei Sengeng, President of Volkswagen Group (China), and Yan Yanfeng, General Manager of China FAW Group Co., Ltd., jointly laid the cornerstone for a new joint venture focused on parts and components. During the event, several key cooperation agreements were signed, marking a new phase in the partnership between the two automotive giants.
The foundation stone ceremony for Volkswagen FAW Platform Parts Co., Ltd. took place in the Changchun Hi-tech Development Zone. The event was attended by Niu Haijun, vice governor of Jilin Province, along with business leaders and media representatives. This joint venture is part of Volkswagen’s broader plan to invest 5.3 billion euros in China by 2008. The current sub-project involves a total investment of 1.42 billion yuan, with Volkswagen holding 60% and FAW holding 40%. The facility is expected to start production by the end of 2005.
The company will primarily produce front axles, sub-frames, and rear axles for passenger cars, as well as suspension, steering, and braking systems. This collaboration is expected to strengthen FAW's parts supply chain and enhance the competitiveness of FAW-Volkswagen vehicles.
On the same day, Volkswagen and FAW also announced plans to build a new engine plant in Dalian. The facility will feature advanced technology, focusing on low emissions and fuel efficiency—aligning with industry trends and government policies promoting environmental sustainability. The project has already been submitted to relevant authorities for approval.
To further expand their partnership, the two companies also signed an agreement to broaden their product range and introduce new models. A key component of this deal is a technology transfer agreement that will allow FAW-Volkswagen to enter the commercial vehicle market. Production of light buses and commercial vans will take place at FAW’s facilities in Jilin City.
All these new initiatives are part of Volkswagen’s overall 2008 investment plan in China, which totals 5.3 billion euros. This continued expansion highlights the strong and forward-looking relationship between Volkswagen and China FAW Group.
High frequency induction heating system is a technology that uses high-frequency alternating current to generate eddy currents in metal workpieces to achieve heating. Its operating frequency is usually between several kilohertz to several hundred kilohertz, and even up to megahertz level. This heating method not only has fast heating speed and high efficiency, but also can achieve highly concentrated heating of metal workpieces, especially suitable for heating treatment of small-sized and complex shaped components.
working principle
The basic principle of high-frequency induction heating system is to use electromagnetic induction. When high-frequency current passes through an induction coil, a strong magnetic field is generated. When a metal workpiece placed in a magnetic field is subjected to magnetic force, eddy currents, or induced currents, are generated inside. These eddy currents convert electrical energy into thermal energy through Joule effect (resistance heating), resulting in rapid heating of the workpiece. It is worth noting that high-frequency current can cause significant skin effect, which means that heat is mainly concentrated on the surface of the workpiece, which is extremely beneficial for some applications that require surface hardening.
Main components
High frequency power supply: Provides high-frequency alternating current.
Induction coil: forms a high-frequency magnetic field.
Cooling system: Keep the coils and other components at a suitable operating temperature.
Control system: Adjust frequency and power, monitor heating process.
Fixtures: Position workpieces and optimize heating efficiency.
Characteristics and advantages
Fast heating speed: High frequency current can instantly heat the workpiece to the desired temperature.
High thermal efficiency: Most of the energy is directly applied to the workpiece, reducing energy loss.
Precise control: Heating depth and area can be controlled by adjusting frequency and power.
Flexibility: Suitable for workpieces of various shapes and sizes.
Pollution free: No harmful gases are produced, and the operating environment is cleaner.
application area
High frequency induction heating systems are widely used in multiple industries:
Metal processing: including welding, forging, and hot forming.
Heat treatment: surface quenching, tempering, annealing, etc.
Jewelry: Welding of gold and silver products.
Electronic components: Solder heating in semiconductor packaging.
Medical equipment: Welding of small components during the production of medical devices.
Automotive industry: Hot assembly of transmission gears, piston pins, and other components.
Development Trends
With the advancement of technology, high-frequency induction heating systems are developing towards higher frequencies, higher power, and greater intelligence. The application and technological improvement of new materials have further improved the energy efficiency of high-frequency induction heating systems, and also promoted their application expansion in emerging fields such as new energy vehicle battery manufacturing and composite material forming. The intelligent control system makes the heating process more precise, improving overall production efficiency and product quality.
