Tank Car And Sprinkler Truck Car Sound Valve Investment Casting

The types of alloys that can be produced by investment casting are carbon steel, alloy steel, heat-resistant alloys, stainless steel, precision alloys, permanent magnet alloys, bearing alloys, copper alloys, aluminum alloys, titanium alloys, ductile iron and other precision castings.

Investment casting, also known as lost wax casting, includes processes such as pressing wax, repairing wax, assembling trees, dipping slurry, melting wax, casting molten metal, and post-treatment. Lost wax casting is to use wax to make a wax mold of the part to be cast, and then coat the wax mold with mud, which is a mud mold. After the clay molds are dried, they are fired into pottery molds. Once roasted, all the wax molds melt and lose, leaving only the pottery molds. Generally, a pouring port is left when making a mud mold, and then molten metal is poured from the pouring port. After cooling, the required parts are made.

The greater advantage of investment casting is that due to the high dimensional accuracy and surface finish of investment castings, it can reduce the machining work, just leave a little machining allowance on the parts with higher requirements, even some castings Only the grinding and polishing allowance is left, and it can be used without mechanical processing. It can be seen that the use of 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 method is that it can cast complex castings of various alloys, especially high-temperature alloy castings. For example, the blade of a jet engine, its streamlined profile and cooling cavity, can hardly be formed by machining technology. Production by investment casting process can not only achieve mass production, ensure the consistency of castings, but also avoid the stress concentration of residual knife marks after machining.
