Su Shizhen: EFD Group is one of the world's largest multinational joint-stock companies producing induction heating equipment. It is headquartered in Germany and has production facilities in Norway, Germany, France and India. Effort Induction Equipment (Shanghai) Co., Ltd. is a wholly-owned company established by EFD Group in Shanghai in June 2001. It introduces EFD's most advanced induction heating manufacturing technology and advanced management mode. It is the EFD Group in China and Asia and even in Asia. The world provides one of the most important bases for the production, sales and technical services of induction heat treatment equipment. 
Attitude towards the Chinese market
Su Shizhen: After the baptism of the short-term economic crisis in the first half of 2009, China's automobile manufacturing industry revived at an alarming rate in the second half of 2009, and broke through the historical sales record of 13 million vehicles in an unstoppable manner. According to the latest statistics, China's automobile production capacity plan will exceed 20 million units in 2010. This development speed is a miracle in the history of world automobile development, but at the same time, this is an unprecedented development for China's auto parts manufacturers. Opportunity.
In recent years, with the dramatic increase in the level of induction heating technology in the world, more than 200 parts in a car have begun to use induction heating technology for heat treatment. More than half of the parts have begun to use induction hardening and tempering. Processes, these parts vary in shape and size, and the heat treatment is quite difficult, requiring equipment suppliers to have advanced technology and rich experience. Yifudi has always been at the forefront of the world's advanced technology in the development and manufacture of induction heating technology, especially in the heat treatment of automotive parts. The machine tools are mainly divided into horizontal and vertical types. They can also be divided into single-station, double-station, rotary table and other forms. In addition, heat treatment production lines that are integrated with quenching and tempering are also available. Conveyor lines and robots can also be integrated into other automated production lines. Therefore, EFD has a variety of proven solutions for handling various simple or complex parts, or heat treatment of highly technical parts.
Solution and technical features
Su Shizhen: Below, a brief introduction to the application of EFD induction hardening technology on several important automotive parts is given.
The heat treatment of the steering rack in the steering system of the automobile is one of the most critical processes in the manufacturing process of the rack. The quality of the heat treatment is directly related to the life safety of the traveling vehicle and the occupant, and the rack is broken due to the heat treatment problem. It can lead to a vicious traffic accident, so all the rack manufacturers never dare to take care of the heat treatment process of the rack. EFD according to the needs of users, combined with decades of experience, can provide two kinds of completely different processing schemes, conductive quenching and scanning quenching, to quench the different parts of the tooth, back and stem of the rack. EFD's rack-induced quenching and tempering technology provides a strong technical guarantee for domestic rack manufacturers. At present, Yifudi Shanghai has provided dozens of various rack quenching and tempering equipment for domestic important gear manufacturers such as Shanghai ZF and Delphi. EFD Shanghai has become the RDX Group Rack Quenching Technology R&D. And manufacturing base. 
The transmission system of the automobile is an important component of the torque of the automobile transmission. The shape of the parts is complex and the size is variable. There are many parts requiring induction hardening, such as the transmission shaft, the universal joint, the bell shell, and the three-column shell. In the case of star-shaped sleeves and worm gears, the technical requirements for induction hardening of such complex shaped workpieces are often extremely high. Therefore, the controllability, repeatability and stability of the inductive power supply equipped with the equipment are particularly high. At the same time, the designers and manufacturers of sensors require a wealth of modern design concepts and process experience. Yifudi Induction Equipment (Shanghai) Co., Ltd. has an experienced design and manufacturing team of machine tools and sensors. With their joint efforts, EFD perfect solutions and high quality products in just a few years. In the past, it provided dozens/set of induction heat treatment processing equipment for well-known domestic transmission equipment manufacturers such as Wanxiang Group and Natiefu, and shared the advanced technology of EFD induction heating with them. 
The engine is the heart of the car, and the crankshaft is the core part of the engine. It requires good fatigue and wear resistance. At the same time, the crankshaft should have high load carrying capacity at low speed torsion. Heat treatment plays an important role in obtaining these characteristics during the manufacturing process of the crankshaft. Induction hardening and tempering technology, as one of the heat treatment technologies of the crankshaft, has low processing cost and good characteristics after processing, and is increasingly favored by crankshaft manufacturers, but because of its high technical content, especially the crankshaft roundness induction. Quenching technology has always been one of the problems that plague the crankshaft induction heat treatment industry. As one of the few companies in the world to master the crankshaft fillet quenching technology, EFD has accumulated decades of manufacturing experience in this field and played an important role in the development of the domestic crankshaft manufacturing industry.
