In order to improve the local cooling rate of stainless steel investment castings, the chiller placed inside the die and on the working surface is called a chiller. In the production of stainless steel castings, chillers, pouring systems, and risers are often used in conjunction to control the solidification process of castings and obtain qualified castings.
Stainless steel precision casting cold iron material selection: there are many materials that can be used to make cold iron, but all high-quality silica sol castings have higher thermal conductivity and heat storage index than sand mold materials. Metal materials and non-metallic materials can be used. Common cold iron materials in manufacturing include pig iron, aluminum alloy profiles, high-purity graphite, and alloy copper. Pig iron has a large heat storage index, can absorb more heat, and has a relatively strong chilling ability. Stainless steel precision casting pig iron is easy to make and low in cost, and it is widely used in the production of aluminum alloy profiles and die-casting aluminum precision casting. When we choose the cold iron material of stainless steel precision casting, we should choose according to the correct method, and it is necessary for us to choose the casting method that suits us.
Stainless steel precision casting is a forging process with little or no drilling. It is an excellent production process in the foundry industry and is widely used by zinc alloy die casting manufacturers. So when we all choose cold iron materials for stainless steel precision casting, what are the general selection methods?
