Selection of stainless steel precision casting cold iron materials

Stainless steel precision casting is an excellent technology in the casting industry. It is a casting process with little or no cutting, and it is widely used. So do you know how to choose cold iron materials for stainless steel precision casting?

 

For the selection of cold iron materials for stainless steel precision casting, there are many materials for making cold iron, and all metal and non-metallic materials with higher thermal conductivity and heat storage coefficient than sand mold materials can be selected. The cold iron materials commonly used in production are cast iron, aluminum alloy, graphite and copper alloy and so on. Cast iron chilled iron has a large heat storage coefficient, can absorb more heat, and has a strong chilling capacity. Moreover, cast iron chilled iron is widely used in aluminum alloy and magnesium alloy precision casting because of its convenient manufacture and low cost, especially when it is placed at the bottom or end of castings to strengthen the solidification order of castings.

 

Stainless steel precision casting is to increase the local cooling rate of castings, and the chilled material placed in the cavity and working surface is called cold iron. Cold iron, gating system and riser are often used together in precision casting production to control the solidification process of castings and obtain qualified castings.

 

When we all choose stainless steel precision casting, we all need to consider more about the choice of stainless steel precision casting cold iron materials, the choice of suitable and satisfactory materials is what we all need.
