Casting process

Cast molding is generally not exert pressure on the less demanding strength equipment and molds for products small size limits the stress within the article is also low. Thus, less productive investment, good performance large parts can be obtained, but a longer production cycle, must be machined after molding. In the traditional casting, based on the derived perfusion, inlay casting, pressure casting, spin casting and centrifugal casting methods.
① perfusion. This method of casting difference: finished products that is escaping from the casting mold; mold while perfusion is part article itself.
Casting process
② inlay cast. The various non-plastic parts placed in a mold cavity, and curing the injected liquid materials together to make it encapsulated therein.
③ pressure casting. When casting exert a certain pressure on the material in favor of the viscous material into a mold, and shorten the filling time, mainly used for epoxy resin casting.
④ spin casting. After the material injected into the mold, the mold at a lower rate of rotation about a single-axis or multi-axis, distributed in the material by gravity cavity inner wall, by heating, curing and setting. For the manufacture of spherical, tubular and other hollow products.
⑤ centrifugal casting. The amount of the liquid material injected into the high-speed rotation around the single-axis, and the heated mold, the material distributed by centrifugal force to the walls of the mold cavity, by physical or chemical action cured tubular or hollow cylindrical article.
