Because zinc alloys are more active and easy to oxidize in the air, zinc alloy die-casting mold parts need to be well stored before and after die-casting, and surface treated after die-casting to make them more durable.
Zinc alloy die-casting requires strict control of alloy composition during the production process. Forgiveness of high-quality zinc alloy is the prerequisite guarantee for the production of high-quality zinc alloy die-casting. Zinc alloy raw materials need reasonable storage to ensure proper temperature and humidity. Good zinc alloy raw materials can guarantee the quality of subsequent die castings. In the die-casting process, the furnace temperature should be controlled at the appropriate temperature of the zinc alloy raw material, which fully guarantees the good fluidity of the zinc alloy liquid, so that it can completely fill the cavity, so that the mechanical properties of the zinc alloy die-casting are stable.
1. Put the zinc alloy die-casting raw materials in a dry and clean place, and it is necessary to carry out sample testing before use.
2. After die-casting the finished zinc alloy die-casting parts, they should be packaged and sealed after surface treatment to avoid the surface of the zinc alloy die-casting parts being oxidized by air.
3. The surface should be pickled, and moisture-proof measures should be taken.
