Die casting post process includes cleaning and deburring, heat treatment, machining and surface treatment these main steps.

Die casting post-processing refers to a series of processing and treatment steps performed on castings. After the die casting process completed to improve their performance, appearance and functionality. These steps usually include the following aspects:

1. Die casting post process：Cleaning and deburring

After the die casting solidifies in the mold, there may be flash (burrs) or oxide residue on the surface. These need to remove by mechanical cleaning or chemical treatment to ensure a smooth and neat surface of the casting.

2. Die casting post process: Heat treatment

In order to eliminate the residual stress generated during the die casting process. And improve the mechanical properties and durability of the casting, the casting is usually heat treated. This includes processes such as annealing, normalizing, quenching and tempering.

3. Machining

Although the die casting process can produce castings close to the net shape, some parts with complex shapes or high precision requirements still need further machining. This may include turning, milling, drilling and other operations to achieve the designed size and tolerance requirements.

4. Surface treatment

In order to enhance the surface quality of the casting or give it a specific function, surface coating, plating or painting may be performed. These treatments can improve the corrosion resistance, wear resistance or aesthetics of the casting.

5. Testing and quality control

Post-processing of die casting also includes various tests on the finished product. Such as dimensional measurement, non-destructive testing (such as ultrasonic testing, magnetic particle testing), and appearance inspection to ensure that the product meets the design specifications and quality standards.

6. Special treatment

Depending on the application requirements, some castings may also require special post-treatment, such as anodizing (for aluminum alloy castings) to improve their corrosion resistance and decorative effect.

Therefore, die casting post-processing is an important part to ensure that die castings achieve the expected performance and quality. It involves a variety of processes and technologies to optimize the overall performance and service life of the product.
