The stainless steel casting process is to melt stainless steel and inject it into a mold, go through process steps such as solidification, cooling, and forming, and finally produce the required product. Stainless steel has the advantages of corrosion resistance, high temperature resistance, and high strength, so it is widely used in various industries. There are many types of stainless steel casting processes, and Dalian stainless steel casting manufacturers will introduce several common process methods below.

1. Sand casting

Sand casting is a traditional casting process and a more widely used casting process. This process involves filling the mold with sand, then injecting molten stainless steel into the mold, and removing it after solidification to obtain the desired product. The sand casting process is simple and flexible, suitable for large, small, and complex shaped castings, but with low accuracy.

2. Precision casting

Precision casting is a high-precision casting process commonly used to manufacture complex shaped and small-sized stainless steel castings. This process uses precision molds to inject molten stainless steel into the mold through methods such as atmospheric pressure and filling pressure. After solidification and cooling, the required products are taken out. The advantages of precision casting technology are high precision and good surface quality, but the manufacturing cost is high.

3. Investment casting

Investment casting is a commonly used casting process suitable for manufacturing large-sized and structurally complex stainless steel castings. This process involves making an investment mold, melting it at high temperatures, and then injecting the melted stainless steel into the mold. After solidification and cooling, the desired product is taken out. The investment casting process can manufacture castings with complex internal structures, but the manufacturing cycle is longer.

4. Process flow

The process flow of stainless steel casting includes steps such as mold manufacturing, melting pool, pouring cooling, and product treatment. Firstly, molds can be made based on the shape and size of the castings, using materials such as sand molds, molds, ceramics, etc. Then, melt an appropriate amount of stainless steel in the furnace and perform temperature control and composition adjustment to ensure the quality of the melt pool. Next, pour the melted stainless steel into the mold and form a casting through cooling and solidification. Clean, trim, and surface treat the castings to obtain the final product.

Summary: The stainless steel casting process includes several methods such as sand casting, precision casting, and investment casting. Each process has different characteristics and applicability, and suitable process methods can be selected according to specific needs. The stainless steel casting process is widely used in various industries, providing reliable process support for the production of stainless steel products.
