Investment Casting Production Process
Our investment casting production process follows a precise sequence of steps to ensure the highest quality components. Each stage is carefully controlled and monitored.
Tooling & Pattern Making
A tool is built to customer-provided specifications. Cold wax is then injected into the tool to create a wax pattern/prototype that maintains dimensional accuracy for final components.
Pattern Assembly
The wax patterns are carefully assembled onto the sprue, creating a tree-like structure that will form the gating system for molten metal flow.
Dipping & Coating
Successive layers of ceramic are applied to the sprue assembly to form a hard shell. Multiple dipping and drying cycles build up the required shell thickness.
De-Waxing & Firing
The molds are flash-fired to remove the wax and sprue materials and then heated to 1,800 degrees and placed on a sand bed, ready for pouring.
Casting
Molten metal, heated up to 3,000 degrees, is carefully poured into the hollow mold and then allowed to cool under controlled conditions.
Knockout
The ceramic shell is broken off, and the individual castings are cut away from the gating system using precision cutting tools.
Finishing
Excess metal is removed, surfaces are finished to specification, and castings undergo heat treatment to achieve desired mechanical properties.
Testing & Inspection
Castings undergo thorough testing and inspection to ensure they meet dimensional tolerances, material specifications, and quality standards.
Packing & Shipping
Castings are securely packaged with appropriate protection for safe shipping to the customer, with full documentation and certificates.
