What are the types of casting mold materials

, steel: in the past, the sand casting mold is mainly used for the production of standard parts and structural parts, less used for the production of casting mold body, because the service life of carbon steel is not higher than that of ductile iron or low alloy gray cast iron, and alloy steel is very expensive.

2, wood mold: Wood mold is still widely used in our country, mostly for manual modeling or single piece of small batch production. However, with the environmental protection, the improvement of awareness and the limitation of poor machining performance of technical materials, solid casting is gradually replacing technical casting.

3, solid casting: solid casting is based on foam sheet material, cut and then paste into the required shape, and finally poured into the casting, the method is shorter than the wooden mold, the cost is low. The application of plastic mold. The upward trend, especially the application of processable plastics is increasingly widespread.

4, aluminum alloy mold: Aluminum alloy mold light weight, high dimensional accuracy, so it is widely used. However, recently, the application has decreased, and some of the market has been replaced by plastic molds and cast iron molds.

5, cast iron mold: Cast iron mold is the first choice for mass casting production, it has high strength, high hardness, good processability, low cost, long service life and other advantages, so it is loved by a large number of factories.
