Lost Wax Investment Casting Process
In lost wax investment casting, a sacrificial detailed wax pattern of the desired finished part is created and mounted onto a wax "tree", which includes the metal delivery system (gates and risers). The tree is alternately dipped into a ceramic slurry and sprinkled with stucco material, and is allowed to dry. This process is repeated until a thick shell is created over the wax pattern. The wax pattern is melted out leaving a cavity in the shape of the pattern. The cavity is filled with molten metal. After solidification, the shell is broken away, the gating material removed, and the finished part remains.
Advantages of Investment Casting
 
How are Investment Castings Made?
Developing investment castings involves creating an original wax model, coating the image with plaster and building of successive layers until a strong shell envelopes the model. After melting out the wax, molten metal will be poured into the mold, creating a perfect duplicate of the original wax pattern. Compared to machining apart, investment casting can economically offer undercuts, high definition, complex detail and a smooth surface finish.
Most often, investment casting is the only way a part can be economically manufactured.
