Precision casting equipment: The common casting process generally does not apply pressure to the casting process, and does not require high strength of the equipment and mold. It has small limitations on the size of the product and low internal stress in the product. Therefore, with less production investment, large components with excellent performance can be produced, but the production cycle is longer and mechanical processing is required after forming. On the basis of traditional casting, methods such as pouring, embedding casting, pressure casting, rotary casting, and centrifugal casting have been derived.

① Perfusion. The difference between this method and casting is that after casting, the product is immediately released from the mold; When pouring, the mold is actually a component of the product itself. Precision Casting Equipment: Common Casting Processes

② Embedded casting. Place various non plastic parts in the mold cavity, solidify them together with the injected liquid material, and encapsulate them inside.

③ Pressure casting. Applying a certain amount of pressure to the material during casting is beneficial for injecting viscous materials into the mold and shortening the filling time. It is mainly used for epoxy resin casting. Precision Casting Equipment: Common Casting Processes

④ Rotating casting. After injecting the material into the mold, the mold rotates around a single or multiple axis at a lower speed. The material is distributed on the inner wall of the mold cavity by gravity and is shaped through heating and solidification. Used to manufacture hollow products such as spherical and tubular shapes.

⑤ Centrifuge casting. Inject a quantitative amount of liquid material into a mold that rotates at high speed around a single axis and can be heated. Use centrifugal force to distribute the material onto the inner wall of the mold cavity, and solidify it into tubular or hollow cylindrical products through physical or chemical reactions (see centrifugal casting). Single casting nylon parts can also be formed by centrifugal casting method. Precision Casting Equipment: Common Casting Processes
