A "Different Deformation" Treatment Method for Aluminum Alloy Die-Cast Parts

① Improve the design of casting structure;
② Reasonably adjust the holding pressure and ejection time;
③ Optimize the ejection position and the number of ejector pins. It is suggested to use 4 ejector pins at the open area;
④ Adjust the location of the gate and reduce the thickness of the gate to ensure product quality and minimize deformation;
⑤ Strengthen the surface treatment of the mold to reduce the ejection resistance;
⑥ Control the local mold temperature and maintain the mold thermal balance.
