Impurity hazards of die-casting parts die-casting by die-casting machine:
1. It will make the alloy structure in the die casting discontinuous;
2. Reduce the air tightness of the workpiece;
3. Die castings are easily corroded;
4. Reduce the strength and plasticity of die castings;
5. Die castings are prone to cracks;
6. The difficulty of later processing increases;
7. The scrap rate of die castings has increased;
8. Harmful impurities cannot pass through environmental protection.
Improving measures for impurities in die-casting parts of die-casting machine:
1. Control the quality of raw materials;
2. The use of secondary materials is strictly in accordance with a reasonable ratio;
3. Use high-quality refining agents for metal smelting;
4. Use ceramic filter;
5. Vacuum melting and conveying;
6. Use ceramic spoons, crucibles, protective tubes, and discard iron tools;
7. Regularly clean up molds, tools, and working surfaces;
8. Use high-quality release agent and other auxiliary materials;
9.Keep the working environment clean.
