　　The rapid development of zinc alloy die-casting parts

　　Because die-casting is a rapidly developing and efficient, low cutting metal forming precision casting method in modern metal processing technology, die-casting parts have been widely used in various fields. The application and development speed of zinc alloy die-casting parts is extremely fast. So many people wonder why the application development of zinc alloy die-casting parts is so rapid? Now let's analyze the reasons with everyone.

　　1. Zinc alloy die-casting parts have high dimensional precision, good surface finish, higher strength and hardness compared to other alloys, relatively stable dimensions, and good interchangeability.

　　2. The productivity of the machine is high, and it can be the first mock examination with multiple cavities. The service life of zinc alloy die castings is relatively long, which can reach hundreds of thousands of times, or even millions of times; Easy to achieve mechanization and automation.

　　3. Surface treatment processes such as electroplating, baking paint, oil spraying, polishing, powder coating, and sandblasting can be carried out.

　　4. The die-casting performance is relatively good, which can be used to cast complex shaped products and thin-walled precision parts. Moreover, the melting point is low, making it easy to form by die-casting.

　　5. Zinc alloy die-casting parts do not absorb iron during melting and die-casting, do not corrode the mold, do not stick to the mold, and also have good mechanical properties and wear resistance at room temperature.
