In general, the material span of casting mold is relatively large. We can choose plastic, aluminum alloy, steel, steel or wood according to the actual requirements and output of customers.

The application of plastic molds is increasing day by day, especially the introduction of machinable plastics to the market and the improvement of the life of plastic molds.

The remarkable characteristics of aluminum alloy die are light weight and high precision. But it is not widely used at present.

Cast iron mold is still the first choice for mass casting production, because it has many advantages such as high strength, wear resistance, easy processing, low cost and long service life. .

In the past, steel was mainly used as standard parts, wear-resistant inserts or linings on molds, and was rarely used to make casting molds, because the service life of carbon steel was shorter than that of nodular cast iron or low-alloy gray cast iron, while the price of alloy steel was very expensive.

Wood grain is widely used in manual modeling or single piece and small batch production. The extensive use of wood has accelerated the desertification of our planet, so this method is unsustainable. Instead, it is full mold casting. Full-mold casting is to cut and glue foam plastic plates into patterns, and then pour them into castings. Compared with wood mold, this method has higher dimensional accuracy and better surface roughness of castings.
