Casting technology on the basis of traditional casting, derive perfusion, potting, pressure casting, such as rotating casting and centrifugal casting method.(3) pressure casting.When casting a certain pressure for the material, is beneficial to the viscous material injection mold, and shorten the molding time, mainly used in epoxy resin casting. (4) spin casting.After the material into a mold, mold at a lower speed around the single or multiple spindle rotation axis, material by gravity distribution on the inner wall of the cavity, by heating, curing and finalize the design.Used to manufacture the spherical, tubular hollow products, etc. (5) centrifugal casting.Injected quantitative liquid material, and can be heated by high speed rotation around the single shaft mold, using centrifugal force distribution on the cavity wall material, through physical or chemical effect of curing for tube or hollow tubular products.
