1) Consumer products  are made with many metal and plastic parts . Metal and plastic machine workers set up  the machines that produce the parts and operate them during production. Hundreds of thousands of machine workers in the manufacturing industry  work in different phases of production: following blueprints , they set up the machinery  to produce the correct product. Machine setters prepare the machines before production and perform test runs of the initial batches , making repairs  or adjustments  as needed to ensure quality control . Then, operators  take over  and may have to load  the machine with metal or plastic materials or adjust machine controls  during production. They periodically inspect the parts and conduct  minor maintenance At completion , they remove  and test finished products, then document  production numbers.

2) Metal and plastic machine operators  may specialize in a particular type of machine, for example: Computer-controlled machine tool operators  operate robots to perform functions  on workpieces Computer numerically controlled machine tool programmers  —called CNC workers— develop computer programs  to control automated processes . They require more training  than other machine workers. Extruding and drawing machine workers  push out  thermoplastic or metal materials in the form of tubes, rods , or hoses Cutting punching  and press machine workers  run machines to saw bend , or straighten  materials. Molding coremaking   , and casting  machine workersrun machines to form metal or thermoplastic parts  or products. 

3) Multiple machine tool  setters, operators and tenders  set up or operate more than one type of cutting or forming machine tool or robot. Manufacturing facilities typically employ machine workers full time, usually in shifts  that include evenings, weekends and frequent overtime . With automation , multiple machines may be controlled at the same time, so workers train on  different machines and gain a variety of skills . Because these workers operate powerful high-speed  machines, most usually wear protective equipment , such as safety glasses earplugs , and steel-toed boots Respirators  are common for those in the plastics industry who work near materials that emit dangerous fumes  or dust . Employers prefer to hire  candidates with high school education, then train  machine operators on the job .
