The pattern is then used to create a mold, which is typically made of ceramic or plaster.
Molten wax is injected into the mold, and then cooled to form a wax replica of the desired part.
Multiple wax replicas are then assembled onto a wax sprue, forming a tree-like structure called a wax pattern.
The wax pattern is then coated with a ceramic shell, typically using a dipping process.
The ceramic shell is then heated, causing the wax to melt and run out of the mold, leaving a hollow cavity in the shape of the desired part.
Molten metal is poured into the ceramic shell, filling the cavity and taking on the shape of the desired part.
The cast part is then removed from the ceramic shell, and any excess material is removed using cutting or grinding tools. The part may also be polished or coated to achieve the desired surface finish.
