Casting process

Casting molding generally do not exert pressure on the equipment and mold strength requirements are not high, the product size limit is small, the product is also low internal stress. Therefore, the production of less investment, can be made excellent performance of large parts, but the production cycle is longer, after forming to be machined. In the traditional casting on the basis of derived perfusion, embedded casting, pressure casting, rotary casting and centrifugal casting and other methods.

① perfusion. The difference between this method and casting is that the finished product is removed from the mold and the mold is part of the product itself.

② embedded casting. A variety of non-plastic parts are placed in the mold cavity and are solidified together with the injected liquid material to be enclosed therein.

③ pressure casting. In the casting of the material to exert a certain pressure, is conducive to the viscous material into the mold, and shorten the filling time, mainly for epoxy resin casting.

④ rotary casting. The material into the mold, the mold at a lower speed around the uniaxial or multi-axis rotation, the material by gravity distribution in the cavity wall, by heating, curing and stereotypes. Used to manufacture spherical, tubular and other hollow products.

⑤ centrifugal casting. The quantitative liquid material into the single-axis high-speed rotation, and can be heated in the mold, the use of centrifugal force to distribute the material to the inner wall of the cavity, the physical or chemical role of curing into tubular or hollow cylindrical products (see [ casting]). Monolithic nylon parts can also be molded by centrifugal casting.
