What is cold iron in stainless steel precision casting?

Stainless steel precision casting is a cutting or non-cut casting process. It is a mature process technology in the foundry industry and has a wide range of applications.

To increase the local cooling rate of stainless steel precision castings, the cold objects placed in the mold cavity and on the working surface are called cold irons. In the production of stainless steel precision castings, cold irons, pouring systems and risers are used to control the solidification process of the castings to obtain Qualified castings.

In stainless steel precision casting, there are many materials that can be used to make cold iron. Metal and non-metallic materials with large thermal conductivity and heat storage coefficient can be selected. Commonly used cold iron materials in production include cast iron, aluminum alloy, graphite and copper alloy. Cast iron Chilled iron has a large heat storage coefficient, can absorb more heat, and has strong cooling capacity.

It can use a wide range of materials and can use a large amount of scrap metal and renewable resources. Its consumption is less than ordinary forging methods. Castings have certain dimensional accuracy and small machining allowances, saving processing time and metal materials. .
