1. Investment casting

Investment casting is a high-precision and high-quality casting process, which is suitable for the production of precision castings with complex shapes and high precision requirements. It is characterized by the use of refractory materials to make molds, heating the molds to a high temperature state, and then injecting high-temperature molten metal materials for casting. Due to the small thermal expansion coefficient of the mold and the good surface quality of the casting, it is suitable for producing parts with high precision requirements.

2. Low pressure casting

Low pressure casting is a casting process based on gravity and pressure, which is suitable for the production of castings with high precision requirements. Its characteristic is to put the pretreated metal rod or block into the mold, and then use the force of low-pressure gas or vacuum to push the metal liquid into the mold. Low-pressure casting is suitable for producing high-quality precision castings due to its ability to reduce gas defects and impurities.

3. Precision die casting

Precision die casting is a high-precision and high-yield casting process, which is suitable for producing a large number of precision casting stainless steel castings. It is characterized by the use of high pressure to inject metal materials into the mold, and the use of high-speed cooling and rapid discharge to achieve rapid production. Because of its high production efficiency and low cost, it is widely used in automobile, electronics, aviation and other fields.

4. Precision casting

Precision casting is a high-precision and high-quality casting process, which is suitable for the production of precision castings with complex shapes and high dimensional accuracy requirements. It is characterized by the use of special molds and heating equipment, so that the metal material can flow at high temperatures, so as to achieve precise pouring. Precision castings have the ability to control material flow and solidification processes, and are suitable for producing high-quality precision castings.

Changes of Internal Elements in 304 Stainless Steel Precision Casting Process

The order, time and method of addition of various alloying elements have a great relationship with the recovery rate. The addition sequence and time of alloy elements are determined according to the following requirements: the added alloy elements should be melted as soon as possible to make the composition uniform; The recovery rate of alloy elements should be high, that is, to reduce the burning loss of alloy elements and not to increase the impurities in steel; Impurities and gases brought by alloy elements should be removed.
