The temperature control of zinc alloy die casting molding is very critical, because the temperature has a great impact on the moliding quality and performance of the casting. The following are some methods to control the temperature of zinc alloy die casting:

1. Control melting temperature: The melting point of zinc alloy is low, generally around 380 ° C, so it is very important to control the melting temperature. It is usually recommended to control the melting temperature between 390 ° C and 420 ° C to ensure that the zinc alloy can be fully melted and the temperature is not too high.

2. Control mold temperature: The temperature of the mold also has a great impact on the quality and performance of the molding. It is usually recommended to preheat the mold to more than 200 ° C, and control the temperature of the mold through water cooling during the production process to ensure molding quality and production efficiency.

3. Control zinc alloy injection temperature: Zinc alloy injection temperature should be the same or slightly lower than the melting temperature to avoid defects such as pores and scars on the surface of the casting.

4. Control injection time and pressure: Injection time and pressure are also important factors affecting the quality of zinc alloy die casting. It is usually recommended to adjust the injection time and pressure according to the specific casting requirements to ensure the density and surface finish of the casting.

To sum up, controlling the temperature of zinc alloy die casting molding needs to consider a number of factors, and conduct comprehensive management and monitoring to ensure the molding quality and performance of the casting.
