Industry & Occupation
Classification
Summary
A technical job that uses fine wax models to perform high-precision metal casting.
Description
Lost-wax workers create patterns using wax, apply refractory materials to manufacture molds, remove the wax through firing, pour in molten metal for casting, and finish the final product by removing burrs and polishing the castings. This technique is used in a wide range of fields, including precision parts, jewelry, and automotive components. Temperature control throughout the entire process and understanding of material properties are required.
Future Outlook
Demand for precision casting remains stable, with continued needs in jewelry and precision parts fields. On the other hand, the introduction of new technologies such as 3D printing requires integration with traditional techniques and acquisition of advanced skills.
