The water-cooled die-casting motor housing is generally composed of two die-casting parts: the outer shell and the water jacket. After a series of processes including welding processing, hot sleeve assembly, friction stir welding, post weld treatment, and testing, a sealed water-cooled chamber motor housing is finally formed. The die-casting of motor housings generally adopts high-pressure casting technology, but there is a process defect in high-pressure casting, which is that it is easy to be involved in airflow during the casting process, the forming pores shrink, and the heat treatment also produces bubbles, which poses a great safety hazard to the motor housing. Currently, the pass rate of die-casting motor housings in this industry is only 70%, and the scrap rate is very high. The water jacket is the core part of the die-casting motor housing, nested with the motor stator to ensure the normal operation of the rotor. Its airtightness, force performance, and concentricity directly affect the safety performance of the motor. Therefore, we have improved the die-casting motor housing process based on the water jacket forming and welding technology. The casing hosing is die cast metal. We provide custom electric motor shell and custom Fine Processing according to your drawing.
