In aluminum, magnesium alloy die-casting molds, and gravity metal mold-casting molds, the design of the cooling system is also a key. The cooling system sometimes called the cooling pipe or the cooling circuit is composed of a series of high thermal conductivity materials. Its purpose is to take the heat away from the molten metal through direct heat conduction and realize the control of the mold temperature. Controlled, and directed cooling, to allow castings to cool as quickly as possible.
The process of pouring molten metal into a mold cavity in the shape of casting, and taking out the finished product after the metal is cooled, is commonly known as sand casting, also known as sand casting. Each sand mold can only be used once, which belongs to destructive casting. Mainly cast steel, aluminum alloy, and copper.
