The R&D and design of any product must rely on proper selection of raw materials, advanced technological measures, stable parts, and perfect manufacturing process before it can be fully transformed into the product. Raw materials, manufacturing process and production line are the key elements of design transformation.

1) Material property requirements for key components of electric vehicle DC contactors                                     

2) Key process design and equipment support

Manufacturing process is a sufficient condition to ensure reliable quality and stable performance, must depend on certain hardware establishment to be able to safeguard, Tooling equipment and production line should bear the brunt.

1. Welding technology and welders

      Laser welding technology is the key technology to guarantee product quality and reliability, the main purpose of welding is to ensure good sealing effect, the coil and contact are free from oxidation and pollution, ensure the stability of contact resistance.

Necessary equipment: laser welding machine, air tightness detection device, vacuum and gas filling device.

2. Packaging technology and equipment

Pouring technology is one of the key technologies of epoxy sealant contactor. The combination degree of the gel and the product and the density degree of the gel are the key points to be guaranteed.

Necessary equipment: filling machine, vacuum table, drying device.

3.  Testing process and equipment

The electrical life of contactor is a key performance index. Loading failure test is the last safeguard checkpoint before the product leaves the factory.

Necessary equipment: Dc power supply, resistance load, intelligent control and protection device
