- No casting draft required
- High precision and accuracy
- Smooth casting surfaces
- After Tooling, inexpensive production costs for complex cast geometries and assemblies.
- No VOCs, hazardous material or waste. A green casting solution.
The investment casting process, also known as lost-wax casting, is capable of producing intricate castings without any parting lines.
At Sycast, we only utilize the solid-mold variant of investment casting. Solid mold investment castings have the following advantages over ceramic-shell investment castings:
- Improved dimensional stability
- Lower costs for prototype and low-volume quantities
- Solid mold properties are easily adjusted by altering the ceramic slurry formula, for fine tuning of casting accuracy and processing speed.

The Solid Mold Investment Process
A wax pattern replica of the desired cast part is produced by injecting wax into an aluminum die or by Tool-less Casting methods. The patterns are glued to a sprue, creating a "tree" of wax patterns. Under vacuum (to eliminate air bubbles), a ceramic slurry is poured around the tree, and, after solidification, the ceramic mold is placed in a steam-chamber to melt out the wax patterns.
The hollow ceramic mold is then fired in a kiln at temperatures of up to 2000F, to eliminate any wax residue and moisture from the molds. The ceramic mold is then ready for metal to be cast.
