Zinc alloy die-casting is a process with equally prominent advantages and disadvantages. The advantage is that zinc alloy die-casting has high efficiency and can produce many complex precision parts; the disadvantage is that zinc alloy die-casting has high gas content, large linear shrinkage coefficient, and easy to appear There are few defects, fewer surface treatments can be performed, and the yield rate is low.
I don't know if you have heard of alloys. In fact, the common and common alloys currently on the market are mainly aluminum alloys, zinc alloys, iron alloys, etc., but there is no copper alloy because copper is not suitable for alloys. In fact, the common alloy material in the industrial market is zinc alloy, and most of the current die castings are zinc alloy. At the same time, the quality of die-casting parts is very important, but if you want to ensure its quality, you must use high-quality die-casting materials. So, what are the basic requirements for the structure of zinc alloy die castings?
1. Eliminate undercuts and deep cavities as much as possible, and minimize core pulling to ensure that the zinc alloy die-casting parts can be smoothly taken out of the die-casting cavity.
2. The wall thickness of zinc alloy die castings should be uniform.
3. Avoid sharp corners to reduce casting stress
