jiachuancasting 0 10 марта, 2023 Investment casting, also known as lost wax casting, is a manufacturing process in which wax patterns are used to create disposable ceramic molds. Wax patterns are made to the exact shape of the item to be cast. This pattern is coated with refractory ceramic material. After the ceramic material has hardened, it is heated upside down until the wax melts and flows out. The hardened ceramic shell becomes a one-time investment mold. The molten metal is poured into molds and allowed to cool. The metal casting is then removed from the used mold. The term investment casting comes from the process of "cladding" (surrounding) a pattern with refractory material. Investment casting is often chosen over other forming methods because of the fine detail and excellent as-cast surface finish of the resulting castings. They can also be cast with thin walls and complex internal channels. Unlike sand casting, investment casting does not require draft.
