Investment Casting

Investment casting is also called lost wax casting, including waxing, waxing, grouping, dipping, melting wax, casting molten metal and post-treatment. Lost wax casting is a wax mold in which a part is to be cast with wax, and then the wax mold is coated with mud, which is a mud mold. After the mud mold is dried, the internal wax mold is melted by placing it in hot water. The mud mold from which the wax mold has been melted is taken out and baked into a ceramic mold. Once roasted. In the general clay mold, the pouring port is left, and the molten metal is poured from the pouring port. After cooling, the required parts are prepared.
The biggest advantage of investment casting is that because of the high dimensional accuracy and surface finish of the investment casting, the machining work can be reduced, but only a small amount of machining allowance is required on the parts, even some castings only The grinding and polishing allowance can be used without machining. It can be seen that the investment casting method can save a lot of machine tool equipment and processing man-hours, and greatly save metal raw materials.
Another advantage of the investment casting process is that it can cast complex castings of various alloys, particularly casting high temperature alloy castings. For example, the blade of a jet engine, the streamlined profile and the cooling cavity, can hardly be formed by a machining process. The production by the investment casting process can not only achieve mass production, but also ensure the consistency of the castings, and avoid the stress concentration of the residual knives after machining.
