How Investment Casting Works
Investment casting, also known as “lost wax casting”, usually involves coating the surface of a wax pattern with several layers of refractory material. After it hardens and dries, the wax pattern is melted away to form a mold shell. The liquid metal material is then poured into the shell, after cooling, it is solidified to obtain the desired cast parts.
Since the parts made from investment casting process have high dimensional accuracy and surface finish, it is also called “precision investment casting”. The types of alloys that can be produced by investment casting include carbon steel, alloy steel, heat-resistant alloys, stainless steel, copper alloys, aluminum alloys, titanium alloys and nickel based alloys, etc.
The shapes of investment castings are generally complex. At CFS Foundry, the minimum diameter of the holes that can be cast can reach 0.5mm, and the minimum wall thickness of the castings is 3mm. In production, some parts that were originally composed of several parts can be combined. By changing the structure of the part, the design becomes an integral part, it is directly cast by investment casting, so as to save both production time and material cost, which makes the part structure more reasonable.
Investment castings typically weigh between 20g and 60kgs. While it is possible to produce heavier castings, it becomes more challenging and the sand casting process may be a more suitable alternative in such cases.
