Precision Metal Steel Cast Iron Aluminum Lost Wax Vacuum Investment Casting Parts
1. Investment casting, also known as lost wax casting, wax casting or precision investment casting, is a casting process for manufacturing complex shapes and high-precision parts. The process typically includes the following steps:
(1) Mold manufacturing: First make molds according to product design requirements. Molds can be made of metal materials (such as aluminum alloy, steel, etc.) or refractory materials (such as gypsum, ceramics, etc.). Molds are used to make wax molds.
(2) Wax mold injection mold: melted wax material is injected into the mold to fill the mold cavity and form a wax mold similar to the final product.
(3) Wax mold assembly: a number of wax molds are assembled together to form a complete mold assembly, including feeding system, pouring system, etc.
(4) Vacuum dewaxing: the wax mold is placed in the vacuum dewaxing equipment, and the wax material in the wax mold is melted and evaporated by heating and vacuuming, so that the internal cavity of the wax mold becomes a cavity.
(5) Smelting metal: smelting appropriate metal alloys, usually using electric arc furnaces, induction furnaces or argon arc furnaces and other equipment for smelting.
(6) Casting injection: the preheated mold assembly is placed in the casting equipment, and the molten metal is injected into the mold cavity to fill the entire internal cavity of the wax mold.
(7) Cooling curing: After the metal is cooled and cured, the mold assembly is removed from the casting equipment.
(8) Mold crushing: the cooling solidified metal parts are separated from the mold, and the mold is often broken by mechanical or chemical methods to obtain the final casting.
(9) Finishing processing: finishing, removing residual material, deburring and other processing processes on the casting to obtain the final product that meets the requirements.
Investment casting process is suitable for the manufacture of complex, high-precision, high-quality parts, commonly used in aerospace, aviation engines, automobiles, medical equipment, electronics and other fields. It enables the production of parts with complex shapes, small structures and precise dimensions.
