Explanation

The method by which molten metal solidifies in a pre made mold to obtain ingots or castings of specified shape and size, also known as model foundry or full mold foundry during casting production. According to the injection method of metal liquid, it can be divided into upper injection method and lower injection method; According to the conditions of model placement, it can be divided into car casting and pit casting; According to mold, materials can be divided into sand mold, metal mold, ceramic mold, etc. Sand mold casting is widely used in the production of cast iron, and metal mold casting is widely used in nonferrous metal castings and castings in large quantities, while metal mold casting is only used in the production of steel ingots for some special high alloy steels.
