Metal and Plastic Machine Workers
1. OVERVIEW
Metal and plastic machine workers set up, operate, and monitor equipment that shapes metal and plastic into parts used across countless industries. They may specialize in CNC (computer numerically controlled) machines, molding machines, casting equipment, or heat-treating tools. Workers can be found in automotive, aerospace, plastic fabrication, and general manufacturing facilities.
