Wax Injection
Wax injection is the process of creating a replica of the final product using molten wax. The wax is heated to a semi-liquid state and injected into the die under controlled pressure and temperature. Once cooled and solidified, the wax pattern is removed carefully from the die. This wax pattern accurately represents the final casting in shape and dimensions.
Precision at this stage is essential because any defects in the wax pattern will transfer to the final product. Both automatic and manual injection machines are used depending on production requirements. The process ensures uniformity, smooth surface finish, and dimensional accuracy for further stages.
