Industry & Occupation
Classification
Summary
A profession that shapes casting molds such as sand molds using refractory materials and patterns, responsible for the foundational process of metal casting manufacturing.
Description
Molders (casting manufacturing) are specialists who shape casting molds (sand molds and cores) necessary for metal casting production. They assemble sand mold boxes from wood patterns or resin patterns, pack and ram sand mixed with refractory materials into the mold boxes, insert cores, and complete the casting molds. After use in the casting process, they perform mold breaking and cleaning for reuse, as well as dimensional measurements and defect inspections. The work involves high-temperature and dusty environments, handling heavy objects, and quality depends on skill level, making the inheritance of experience from skilled workers essential.
Future Outlook
Demand for castings in automobiles and industrial machinery will remain stable, but progress in labor reduction and automation will require high specialized skills and efficiency improvements. Skill inheritance due to aging is a challenge, and demand for skilled technicians is expected to continue.
