How to solve the problem of uneven surface of zinc die castings.black anodized aluminum t slot

　　Do you know how to solve the problem of uneven surface of zinc die-casting, which is a common problem in the die-casting process among various defects?

　　The insufficient temperature of the die-casting mold is the first reason for surface roughness. When the temperature of the die-casting mold is low, it will affect the cooling and condensation speed of the metal liquid. If the cooling speed is too fast, it will cause inconsistent cooling speed of the casting, resulting in surface roughness. The second reason is that the polishing work is not done well. The flatness of the mold surface is directly related to the flatness of the casting, so mold polishing is extremely important. If the die-casting mold itself has unevenness problems, coupled with inadequate polishing work, this will lead to uneven surface of the casting. After understanding the above reasons, we can solve the problem by adjusting the mold temperature and polishing the mold.

　　The measures to prevent surface unevenness of zinc die castings are simple two points, which can be stopped from the source to produce excellent die castings
