How to solve the stain on the surface of zinc alloy die casting processing?
How to solve the stain on the surface of zinc alloy die casting processing? What is the impact of the material on the surface of the die casting aluminum mold? Surface contamination will damage the die-casting aluminum mold and waste the die-casting raw materials, so how should this problem be solved?
First, check whether the temperature of the die-casting aluminum mold is normal, and reduce the temperature appropriately;
Second, check whether the release agent ratio is correct, if found abnormal need to replace the release agent immediately;
3. Before polishing the surface of the die-cast aluminum mold, if it is an oxidized mold, it should be carefully polished to avoid damaging the nitriding layer on the surface;
Fourth, the design and structure of the pouring system can be changed to avoid continuous erosion of the cavity wall or core;
5. And modify the cooling system of the mold;
Six, in the moving mold grinding a few cross groove, so that the surface of the die casting will be pulled very bright, will not be damaged, the die casting to the moving mold can solve the problem of too many times in the production process.
