Die Casting Process

Find precision die casting parts for various applications. Our China-based factory offers OEM and custom services. High-quality metal and alloy castings.

1. Mold design

The first step in die casting is mold design. The quality of the mold design directly affects the forming and performance of the final part. Our engineers carefully consider the structural features of the part, forming process, and material flow to ensure the highest product quality.

2. Die Casting Process Parameter Setting

Based on the specific requirements of each part and the characteristics of the selected zin/aluminium/magnesium alloy, we set appropriate die casting parameters—including injection speed, injection pressure, and mold temperature. Proper parameter settings ensure precise forming and excellent surface quality of the finished parts.

3. Die Casting Execution

Once the mold design and process parameters are finalized, the actual die casting can begin. Our experienced operators strictly follow the established procedures at every stage, ensuring accuracy and production stability.

4. Melting and Pouring

Melting and pouring are critical steps in the magnesium die casting process. GuangWei precisely controls furnace temperature and melt composition to guarantee the quality of the molten metal. During pouring, the molten zin/aluminium/magnesium is quickly and accurately injected into the mold to prevent premature solidification.

5. Grinding/polishing

After die casting, the parts undergo various post-treatment and surface finishing processes, such as trimming excess material, degassing, sandblasting, and precision machining. These steps enhance the quality and surface finish of the final products.

6. Inspection and Quality Control

The final step involves rigorous inspection and testing of the die cast products. We use methods such as X-ray flaw detection, ultrasonic testing, and hardness testing to check for any defects, ensuring that all products meet or exceed design specifications and customer requirements.
