High Precision Investment Casting Solutions

Our investment casting process manufactures precision components up to 35kg with exceptional dimensional accuracy of 0.5% of length. Ideal for complex geometries and smooth surface finishes, this method delivers superior quality metal parts for various industries.

The Investment Casting Process

1. Pattern Creation: Wax patterns are injection molded into metal dies, with multiple patterns assembled into a tree-like gating system that guides molten metal flow.
2. Mold Creation: The pattern tree undergoes multiple ceramic coating applications to build a robust shell mold, followed by wax removal through heating.
3. Pouring: Preheated ceramic molds receive molten metal at approximately 1000°C (1832°F) through gravity, vacuum, or pressure pouring methods.
4. Cooling: Controlled solidification ensures optimal metallurgical properties based on part thickness and material specifications.
5. Casting Removal: Advanced techniques like water jets or liquid nitrogen separate castings from ceramic molds and gating systems.
