Suggestions on the development trend of stainless steel precision casting

Stainless steel precision casting is a forging process with little or no drilling. It is an excellent production process in the foundry industry and its application is very common. Stainless steel precision casting is also the main trend of forging production. In order to promote the development of precision casting industry in China, it needs to promote the following four overall goals. Stainless steel precision casting technology in addition to many factories, in the field of stainless steel precision casting in our country, it should also focus on these four levels.develop:

1. Improve the quality and credibility of castings, and produce high-quality near-net-shape castings;

2. Reduce the supply cycle;

3. Protect the ecological environment and reduce or even eliminate environmental pollution;

4. Reduce product cost.

In order to increase the cooling rate of stainless steel precision casting castings, the chilled material placed inside the cavity and on the surface of the work is called chilled iron. In the production of stainless steel precision casting, the cold iron, pouring system and gate are often used in conjunction with each other to manipulate the whole process of castings to obtain standard castings.

The selection of stainless steel precision casting cold iron materials, there are many materials that can be made into cold iron , Any metal material and non-metal material material with higher thermal conductivity and heat storage index than sand mold material can be used. Common cold iron materials in production include cast iron, aluminum alloy profiles, high-purity graphite and alloy copper. Cast iron cold iron has a large heat storage index, can absorb more heat, and has a stronger chilling capacity. Stainless steel precision casting cast iron and cold iron are easy to make and low in cost. They are widely used in the production of aluminum alloy profiles and die-cast aluminum precision casting.

In the case of selecting the cold iron materials for stainless steel precision casting, we all choose according to the appropriate method.FitThe way of forging.
