Discuss the methods of improving the quality of precision castings

How can steel casting manufacturers improve the quality of precision castings? What are the methods?

1. Overall process planning:

Steel casting manufacturers should strictly control the process, before packaging, to ensure the appearance and sand core temperature, in the pouring process also need to ensure the circulation of liquid steel, for the appearance is not smooth damaged areas, manufacturers can choose alcohol zirconium powder building paint brush fire baking, so that the appearance of the casting mold polishing.

2. Overall mold planning:

The appearance of precision castings should start from the mold, and the surface of the mold should be clean. For castings with high precision standards, steel casting manufacturers can also choose metal materials or plastic molds to further improve the smoothness of the appearance of the mold.

3. Polishing Polishing master Plan:

In the polishing stage, the manufacturer must remove burrs, for the appearance of irregular, can be ground to solve, too much wetting.

4. Overall wall thickness planning:

The low wall thickness of precision castings is greater than that of sand castings because of the faster heat removal rate of metal material type.

In general, this is the method that steel casting manufacturers summarize for us to improve the quality of precision castings. This is also a problem that manufacturers must pay attention to during the casting process. Only by fully considering the key points can we cast high-quality casting products.
