What is Lost Wax Investment Casting?
Lost Wax Investment Casting, also known as Precision Investment Casting, is a manufacturing process in which a wax pattern is coated with ceramic material to create a mold. After the ceramic shell hardens, the wax is melted and removed, leaving a cavity that is filled with molten metal.
This process produces highly accurate metal components with excellent surface finish, intricate geometries, and minimal machining requirements.
The investment casting process is ideal for manufacturing components with:
- Complex geometries
- Thin sections
- Fine details
- Tight dimensional tolerances
- Smooth surface finishes
- High mechanical strength
Why Choose Lost Wax Investment Casting?

Investment Casting Process
Every casting project follows a carefully controlled manufacturing process.
1. Design Review
Customer drawings and technical specifications are analyzed to determine manufacturability.
2. Tooling Development
High-precision tooling is manufactured for wax pattern production.
3. Wax Pattern Production
Wax patterns are produced using precision dies to ensure consistent dimensions.
4. Pattern Assembly
Multiple wax patterns are assembled onto a central runner system.
5. Ceramic Shell Building
The assembly is repeatedly coated with ceramic slurry and refractory sand to create a strong shell.
6. Dewaxing
The wax is removed using steam or heat, leaving a hollow ceramic mold.
7. Metal Pouring
Molten metal is poured into the ceramic shell under controlled conditions.
8. Shell Removal
After solidification, the ceramic shell is broken away to reveal the casting.
9. Finishing
Components undergo fettling, grinding, heat treatment, machining, and surface finishing.
10. Quality Inspection
Final inspection ensures every casting meets customer specifications before dispatch.
