Investment Casting
Precision casting solutions for complex geometries and intricate designs
How Investment Casting Works
A sophisticated six-step process delivering precision results
Pattern Creation
The process begins with the creation of a wax pattern that mirrors the final product in shape and size. This pattern is typically made using injection molding for consistency and precision.
Shell Formation
The wax pattern is then coated with a ceramic slurry, forming a shell around it. This shell is built up through multiple coatings, ensuring it is robust and can withstand the molten metal's temperature.
Wax Removal
Once the ceramic shell is dry, the wax inside is melted and drained out, leaving a hollow cavity in the shape of the desired part. This is where the "lost-wax" name originates.
Pouring
Molten metal is then poured into the ceramic mold. The metal fills the cavity, taking on the shape of the original wax pattern with exceptional accuracy and detail.
Shell Removal
After the metal solidifies, the ceramic shell is broken away, revealing the cast part. This step requires careful handling to preserve the integrity of the finished component.
Finishing
The cast part undergoes various secondary processes such as polishing, drilling, tapping, grinding, and milling to achieve the desired finish and specifications.
