1. The project belongs to automobile molds. The air tightness requirements of the product are relatively strict, and the upper mold plan adopts the plan of bottoming at the wall thickness position to reduce the post-treatment process of the product surface.

2. The crystallizer water inlet, slag discharge and cooling system of this project are designed reasonably, which effectively guarantees the yield of the product.

3. After testing, the air-tightness and stability of the auto cover die-casting and the strength and wear resistance of the casting fully meet the standard requirements of auto parts.
