Investment Casting Process

Step 1

Creating the Wax Pattern

The process begins with the creation of a wax pattern, which is an exact replica of the part to be cast. The wax patterns are typically produced by injecting wax into a metal mold.

Step 2

Assembly of the Wax Pattern

Multiple wax patterns are assembled onto a central wax gating system, forming a tree-like structure. This assembly is known as a wax tree.

Step 3

Shell Building

The wax tree is repeatedly dipped into a ceramic slurry and coated with fine sand. This process is repeated several times to build a thick ceramic shell around the wax tree

Step 4

Wax Removal

The ceramic shell is heated in a kiln to remove the wax, leaving a hollow ceramic shell. This process is known as dewaxing.

Step 5

Preheating the Shell

The ceramic shell is preheated to remove any residual wax and to prepare it for the molten metal pouring

Step 6

Metal Pouring

The preheated ceramic shell is filled with molten metal, which takes the shape of the wax pattern.

Step 7

Cooling and Solidification

The filled ceramic shell is allowed to cool and solidify, forming the final metal part.

Step 8

Shell Removal

Once the metal has cooled and solidified, the ceramic shell is broken away, revealing the cast metal part.

Step 9

Cutting and Finishing

The cast metal parts are cut from the gating system, and any necessary finishing operations,such as grinding, machining, or heat treatment,are performed to achieve the final specifications.

Step 10

Quality Inspection

The final cast parts undergo rigorous quality inspection to ensure they meet the required specifications and standards.
