Precision casting and investment casting are in a relationship of inclusion and inclusion.
Investment casting is a typical process of precision casting, with the main differences being:
Definition Scope
Precision casting: A general term for processes aimed at producing precisely dimensioned castings, including various methods such as investment casting, ceramic mold casting, and metal mold casting.
Investment casting (also known as lost wax casting): A mold is made from a fusible material (such as wax), which is then coated with a refractory material to form a shell. Molten metal is then poured into the mold to produce the casting. This is a specific method of precision casting.
Process Characteristics
Precision casting: Emphasizes the use of precise molding methods to achieve castings close to the final shape of the part, minimizing machining effort. It is a near-net-shape process.
Investment casting: Using a wax pattern as its core, investment casting requires steps such as coating with refractory material, dewaxing, and firing the shell. It is suitable for the production of complex, precision parts.
In practice, investment casting is often categorized as a representative form of precision casting. While the two processes overlap, investment casting is a specialized branch of precision casting.
