Main Process Of Investment Casting

1. Pattern Creation:

A wax pattern (or plastic pattern) is made, typically using injection molding. This pattern is an exact replica of the desired part.

2. Assembly:

Multiple wax patterns can be attached to a central wax sprue to form a "tree," which allows for the production of multiple parts simultaneously.

3. Ceramic Shell Formation:

The wax assembly is dipped into a slurry of ceramic material, coated with fine sand, and allowed to dry. This process is repeated several times to build a thick, durable ceramic shell.

4. Wax Removal:

The ceramic-coated assembly is heated to melt and remove the wax, leaving a hollow mold cavity. This step is where the term "lost-wax casting" originates.

5. Metal Pouring:

Molten metal is poured into the preheated ceramic mold, filling the cavity where the wax pattern once was.

6. Cooling and Solidification:

The metal cools and solidifies inside the mold.

7. Shell Removal:

The ceramic shell is broken away to reveal the cast metal parts.

8. Finishing:

The cast parts are cut from the sprue, cleaned, and may undergo additional processes such as machining, polishing, or heat treatment.
