What raw materials are used in lost wax casting?

Lost-wax casting is a precision casting technology that uses wax patterns as the main raw material. Wax patterns are made of specific wax materials and usually include the following main components:

1. Paraffin wax: Paraffin wax is one of the commonly used wax model materials. It has a low melting point and good fluidity, making the wax model easy to make and handle.

2. Polymer wax: Polymer wax is a polymer compound with higher thermal stability and strength, and is suitable for more complex and durable casting models.

3. Other additives: In order to improve the performance and process characteristics of the wax model, various additives can be added, such as plasticizers, stabilizers, dyes, etc.

The wax pattern is made into the required shape by methods such as injection molding or 3D printing, and is then used for assembly and coating before casting to form a complete wax pattern assembly. During the casting process, the wax pattern will melt and dewax after being heated. A cavity is left, which is then poured through the casting material to form the desired casting.

It is important to note that the specific formulation and materials used for wax patterns in lost-wax casting may vary depending on the manufacturer and application.
