Investment Casting Process

Precision & Quality

Our investment casting process ensures exceptional dimensional accuracy, superior surface finish, and complex geometries that other methods cannot achieve.

The 8-Step Process

Follow the journey from wax pattern to finished casting through our meticulous, quality-controlled manufacturing process.

Wax Pattern Production
1

Wax Pattern Production

The process begins with creating high-precision wax patterns using aluminum dies that mirror the final product specifications.

Pattern Assembly
2

Pattern Assembly

Multiple wax patterns are assembled on a central wax sprue to form a tree-like structure, optimizing production efficiency.

Ceramic Shell Building
3

Ceramic Shell Building

The wax assembly is dipped repeatedly in ceramic slurry and coated with stucco to build a strong, heat-resistant shell.

Dewaxing
4

Dewaxing

The wax is melted out of the ceramic shell in a steam autoclave, leaving a perfect negative imprint of the pattern.

Shell Firing
5

Shell Firing

The ceramic shell is heated to 1800°F to eliminate any remaining wax residue and strengthen the mold for casting.

Pouring
6

Pouring

Molten metal is poured into the preheated ceramic mold, filling the cavity created by the melted wax pattern.

Shell Removal
7

Shell Removal

After cooling, the ceramic shell is removed through vibration and high-pressure water to reveal the metal castings.

Fettling & Finishing
8

Fettling & Finishing

The castings are cut from the sprue, heat-treated, and undergo precision finishing operations to meet final specifications.
