How to correctly choose cold iron materials for stainless steel precision castings
In order to increase the local cooling rate of stainless steel precision castings, the chill objects placed on the mold cavity and working surface are called cold irons.
Chills, gating systems and risers are often used in stainless steel precision casting production to control the solidification process of castings and obtain qualified castings.
The choice of cold iron materials for stainless steel precision casting can produce many cold iron materials. You can choose metal and non-metal materials with greater thermal conductivity and heat storage coefficient than sand materials.
Cast iron, aluminum alloy, graphite and copper alloy are commonly used cold iron materials in production. Cast iron cold iron has a large heat storage coefficient, can absorb more heat, and has strong chilling ability.
Stainless steel precision casting has low cost and is widely used in the production of aluminum alloy and magnesium alloy precision casting.
When choosing cold iron materials for stainless steel precision casting, we should all choose according to the correct method. We need to choose a suitable and satisfactory casting method.
