Three Methods Of Processing Copper Castings
In the processing of copper castings, the commonly used methods can be divided into metal casting models, centrifugal casting, and sand casting. The metal mold casting copper casting process is a casting method in which liquid metal is filled with a metal mold under the action of gravity, and then cooled and condensed to form a casting.
The metal mold can simply complete the mechanization and automation of the production process, which greatly improves productivity, improves working conditions, and reduces environmental pollution. Due to the high thermal conductivity and heat storage capacity of the metal mold, the liquid metal cools faster in the metal cavity, the structure of the casting is small, and the mechanical properties are high. Metal mold casting has high precision and low surface roughness, which can reduce machining allowance.
Sand casting is a casting method that uses sand to cast castings. Because the modeling materials used in sand casting are cheap and easy to obtain, and the mold is simple, it can be used for single piece production and mass production of castings. For a long time, it has been the basic process of casting production.
Centrifugal casting refers to a casting method in which liquid metal is poured into a rotating mold, and under the action of centrifugal force, the molten metal is filled and condensed into a copper casting. The characteristic of centrifugal casting is that liquid metal is filled and condensed under the action of centrifugal force, the feeding effect is good, the outer layer is finely arranged, there are few non-metallic inclusions, the mechanical properties are good, no forming and core making are required, and equipment investment is saved.
