Investment Casting, also known as precision casting or lost wax casting, is a manufacturing process in which a wax pattern is used to shape disposable mold. A wax pattern is made in the exact shape of the item to be cast. This pattern is coated with a refractory ceramic material. Once the ceramic material is hardened, it is turned upside-down and heated until the wax melts and drains out. The hardened ceramic shell becomes an expendable investment mold. Molten metal is poured into the mold and is left to cool. The metal casting is then broken from the spent mold.

The investment casting process, also known as lost-wax casting, involves several steps to create metal parts with high precision and intricate details. Here is an overview of the investment casting process:
Fuchun produce complex parts from a wide range of investment casting alloys. Our team is committed to quality precision investment casting, and we work with a variety of metals to produce components to your exact specifications. Some precision-casting alloy material options include:
Investment casting offers several advantages that make it a preferred method for producing metal parts with high precision and intricate details.
Lost wax casting allows for the production of parts with complex shapes, intricate details, thin walls, and internal cavities that may be difficult or impossible to achieve with other manufacturing methods.
Parts produced through lost wax casting typically have high dimensional accuracy and tight tolerances, making them suitable for applications that require precise and consistent dimensions.
Lost wax casting results in parts with a smooth surface finish, reducing the need for additional machining or finishing processes.
Lost wax casting can be used with a wide range of materials, including various metals and alloys such as stainless steel, aluminum, bronze, titanium, and more, allowing for flexibility in material selection based on the application requirements.
