Volkswagen and FAW Co., Ltd. started production at the end of 2005
Recently, Volkswagen FAW Platform Parts Co., Ltd. was officially established in the Changchun High-tech Development Zone. On the same day, Volkswagen and FAW Group also signed several new agreements aimed at deepening their collaboration and expanding their joint efforts. The newly formed parts company is a joint venture between Volkswagen Group and China FAW Group Corporation, with Volkswagen holding 60% and FAW holding 40%. With a total investment of 1.42 billion yuan, the facility is expected to begin operations by the end of 2005.
The company will primarily produce front axle and sub-frame assemblies for vehicles, as well as rear axle assemblies, including key components such as the suspension, steering, and braking systems. According to Yang Lin, from Volkswagen (China)'s public relations department, the company will not only serve FAW-Volkswagen but also supply parts to Shanghai Volkswagen.
In addition to the existing cooperation, the newly signed agreements include intent documents for expanding product lines and introducing new technologies. One of the key agreements involves a technology transfer deal for commercial vehicles. As part of this, FAW-Volkswagen is set to enter the domestic commercial vehicle market. However, specific models have not been disclosed yet. Yang Lin mentioned that the new products are currently focused on commercial vans, and the brand name for these vehicles in China has not been finalized.
These commercial vehicles will be manufactured at FAW Group's factory in Jilin City. Moreover, Volkswagen and FAW Group are also working on an engine project in Dalian, which aims to produce low-emission and fuel-efficient engines. This project is still under review by the relevant government authorities.
It’s also reported that the investments for these new projects are part of the previously announced 5.3 billion euro investment plan by Volkswagen Group in China, which is expected to be fully implemented by 2008. This move underscores Volkswagen's long-term commitment to the Chinese market and its strategy to strengthen local partnerships through innovation and expanded production capabilities.
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.
