Manufacturing process for electric drive housing prototypes

With the rapid development of the domestic automobile industry, the trial production of automobile engines and transmissions has changed from relying on foreign trial production companies 10 years ago to the current domestic enterprises playing the leading role, which is highly in line with the current situation of China's automobile market and contributes to the rapid development of the domestic automobile industry.

In recent years, China's automobiles are ahead of the world to realize the rapid development of electrification, and the electric drive technology is more and more popular, the high speed and high efficiency of the electric drive, the electric drive is more and more popular.

The high speed and high efficiency of electric drive inevitably put forward higher demand for the key precision and function test of the shell prototype manufacturing. 

Shell prototypes are mainly manufactured through moldless molding or simple mold sand casting for low-cost, short-cycle verification. The speed of global vehicle R & D speed, the new car market time is getting shorter and shorter, design changes are more frequent, the original prototype test production of the beat and the method can not adapt to the new market, which also gave birth to the prototype test production industry changes, the requirements of faster and better to the design of the accurate verification. At present, the trial production of shell is mainly used for bench test, lubrication test and winter (summer) season test, calibration, etc..
