The problem with the materials of the main working parts of the mold is improper selection of materials. Poor material performance and lack of wear resistance; Mold steel is unrefined and has a large number of smelting defects; Convex and concave molds, incomplete forging process for forging blanks, and residual heat treatment hazards.

1. Wide range of die-casting 2. High dimensional accuracy and low surface roughness of castings 3. High productivity 4. High metal utilization rate 5. High strength and surface hardness of castings

Low density: Plastic has a low density, which is of great significance for reducing the weight of mechanical equipment and saving energy, especially for vehicles, ships, airplanes, and spacecraft.
