Selection of cold iron materials for stainless steel precision casting

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

The choice of stainless steel precision casting cold iron materials, there are many materials that can be used to make cold iron, and all metal and non-metal materials with higher thermal conductivity and heat storage coefficient than sand materials can be used. Commonly used cold iron materials in production include cast iron, aluminum alloy, graphite and copper alloy. Cast iron cold iron has a large heat storage coefficient, can absorb more heat, and has a relatively strong chilling capacity. Stainless steel precision casting cast iron cold iron is easy to produce and low in cost, and it is widely used in the production of aluminum alloy and magnesium alloy precision casting.

When we all choose the cold iron material for stainless steel precision casting, we should choose the correct method. It is what we need to choose our suitable and satisfactory casting method.
