Metal mold casting is a modern technology of making hollow mold with heat-resistant alloy steel. The metal mold can be gravity casting or pressure casting. The mould of metal mould can be reused. Each time liquid metal is poured, one casting can be obtained, with long service life and high production efficiency. Metal mold casting not only has good dimensional accuracy and surface finish, but also has higher strength and less damage than sand mold when pouring the same liquid metal. Therefore, in the mass production of small and medium-sized non-ferrous castings, as long as the melting point of the casting material is not too high, aluminum is generally cast by gravity. However, there are some disadvantages in metal mold casting: because of the relatively high processing cost of heat-resistant alloy steel and its upper hollow cavity, the mold cost of metal mold is not cheap, but the overall cost is much cheaper than that of die casting. For small batch production,



The tooling cost allocated to each product is significantly too high, which is usually unacceptable. However, due to the limitation of die material size, cavity processing equipment and casting equipment capacity, the metal mold can't do anything for the very large castings. Therefore, metal mold casting is seldom used in small batch and large batch production. In addition, although the metal mold is made of heat-resistant alloy steel, its heat resistance is still limited. Generally used for casting aluminum alloy [1], zinc alloy and magnesium alloy. It is seldom used in copper alloy casting and ferrous metal casting. Xudong precision casting factory's metal mold is designed and manufactured by itself, which can provide customers with cheap and practical high-quality mold in time.
