1. Material preparation: First, you need to select a suitable zinc alloy material. The selection of these materials will directly affect the quality, performance and cost of the final product. These materials are then heated to their melting point, causing them to melt into a liquid state for subsequent die-casting operations.

2. Mold preparation: Mold design and manufacturing are key steps in the zinc alloy die-casting process. The shape and size of the mold need to accurately match the shape and size of the required part. In addition, the mold also needs to be able to withstand high temperature and high pressure environments and is usually made of high temperature resistant materials. Mold manufacturing includes a series of steps such as drawing review, material preparation, processing, mold frame processing, mold core processing, electrode processing, mold parts processing, inspection, assembly, flying mold, and mold trial.

3. Die casting: After the mold is prepared and preheated to the appropriate temperature, the liquid zinc alloy is injected into the mold. High pressure is applied through a die-casting machine, causing the zinc alloy to fill the cavity of the mold. This process requires controlled injection speed and pressure to ensure that the molten metal is fully filled in the mold and the required shape and size are obtained.

4. Cooling and solidification: After the die casting is completed, the parts need to be cooled in the mold for a period of time so that the zinc alloy can completely solidify and solidify. In this process, the cooling rate and temperature distribution need to be controlled to ensure that the solidification process of the parts is stable and uniform.

5. Demolding: When the zinc alloy is completely solidified and cooled, open the mold and take out the molded product. The product at this point may require further trimming and processing.

6. Post-processing: The removed zinc alloy parts need to undergo a series of post-processing, including deburring, grinding, polishing, etc., to improve the surface quality and precision of the product.

7. Quality inspection: Finally, strict inspection and quality control of die-cast parts are carried out to ensure that the products meet the specified standards and requirements. This includes checking aspects such as size, appearance and performance of the part.

This is the detailed process of zinc alloy die casting. Each step is very important and needs to be strictly controlled to ensure the quality of the final product.
