Process introduction of casting

December 01, 2021

We made a lot of Investment Casting Parts, as well as Die Casting Mold Development. But what is the process? Casting molding generally does not apply pressure, the strength of the equipment and mold is not high, the size of the product is small, the internal stress in the product is low. Therefore, the production investment is less, can be made of good performance of large parts, but the production cycle is longer, after molding must be machined. On the basis of traditional casting, the methods of casting, inlay casting, Pressure Casting, rotary casting and centrifugal casting are derived.

1) perfusion: The difference between this method and casting is that the finished products are cast out of the mold; While filling the mold is a part of the product itself.

(2) the potting: Various non-plastic parts are placed in the mold cavity, solidified together with the injected liquid material, so that it is encapsulated in it.

③ Pressure casting: Applying certain pressure on the material during casting can help to inject the viscous material into the mold and shorten the mold filling time. It is mainly used for epoxy resin casting.

④ Rotary casting: After the material is injected into the mold, the mold rotates around the single axis or multiple axis at a low speed. The material is distributed in the inner wall of the mold cavity by gravity, and is shaped by heating and curing. For the manufacture of spherical, tubular and other hollow products.

⑤ Centrifugal casting: A quantity of liquid material is injected into the mould which rotates at a high speed and can be heated, and the material is distributed to the inner wall of the mould cavity by centrifugal force. After physical or chemical action, the product is solidified into tubular or hollow tubular products (see figure [centrifugal casting]). Monomer casting nylon parts can also be formed by centrifugal casting.
