Metal and plastic machine workers set up and operate machines that cut, shape, and form metal and plastic materials or pieces.Duties
Metal and plastic machine workers typically do the following:
Consumer products are made with many metal and plastic parts. These parts are produced by machines that are operated by metal and plastic machine workers. In general, these workers are separated into two groups: those who set up machines for operation and those who operate machines during production, however, many workers perform both tasks.
Although many workers both set up and operate machines, some specialize in one of the following job types:
Machine setters, or setup workers, prepare the machines before production, perform test runs, and, if necessary, adjust and make minor repairs to the machinery before and during operation.
If, for example, the cutting tool inside a machine becomes dull after extended use, it is common for a setter to remove the tool, use a grinder or file to sharpen it, and reinstall it into the machine. New tools are produced by tool and die makers.
After installing the tools into a machine, setup workers often produce the initial batch of goods, inspect the products, and turn the machine over to an operator.
Machine operators and tenders monitor the machinery during operation.
After a setter prepares a machine for production, an operator observes the machine and the products it makes. Operators may have to load the machine with materials for production or adjust the machine’s speeds during production. They must periodically inspect the parts a machine produces. If they detect a minor problem, operators may fix it themselves. If the repair is more serious, they may have an industrial machinery mechanic fix it.
Setters, operators, and tenders are usually identified by the type of machine they work with. Job duties generally vary with the size of the manufacturer and the type of machine being operated. Although some workers specialize in one or two types of machinery, many are trained to set up or operate a variety of machines. Machine operators are often able to control multiple machines at the same time because of increased automation.
In addition, new production techniques, such as team-oriented “lean” manufacturing, require machine operators to rotate between different machines. Rotating assignments results in more varied work but also requires workers to have a wide range of skills.
Computer-controlled machine tool operators operate computer-controlled machines or robots to perform functions on metal or plastic workpieces.
Computer numerically controlled machine tool programmers develop computer programs to control the machining or processing of metal or plastic parts by automatic machine tools, equipment, or systems.
Extruding and drawing machine setters, operators, and tenders set up or operate machines to extrude (pull out) thermoplastic or metal materials in the form of tubes, rods, hoses, wire, bars, or structural shapes.
Forging machine setters, operators, and tenders set up or operate machines that shape or form metal or plastic parts.
Rolling machine setters, operators, and tenders set up or operate machines to roll steel or plastic or to flatten, temper, or reduce the thickness of materials.
Cutting, punching, and press machine setters, operators, and tenders set up or operate machines to saw, cut, shear, notch, bend, or straighten metal or plastic materials.
Drilling and boring machine tool setters, operators, and tenders set up or operate drilling machines to drill, bore, mill, or countersink metal or plastic workpieces.
Grinding, lapping, polishing, and buffing machine tool setters, operators, and tenders set up or operate grinding and related tools that remove excess material from surfaces, sharpen edges or corners, or buff or polish metal or plastic workpieces.
Lathe and turning machine tool setters, operators, and tenders set up or operate lathe and turning machines to turn, bore, thread, or form metal or plastic materials, such as wire or rod.
Milling and planing machine setters, operators, and tenders set up or operate milling or planing machines to shape, groove, or profile metal or plastic workpieces.
Metal-refining furnace operators and tenders operate or tend furnaces, such as gas, oil, coal, electric-arc or electric induction, open-hearth, and oxygen furnaces. These furnaces may be used to melt and refine metal before casting or to produce specified types of steel.
Pourers and casters operate hand-controlled mechanisms to pour and regulate the flow of molten metal into molds to produce castings or ingots.
Model makers set up and operate machines, such as milling and engraving machines to make working models of metal or plastic objects.
Patternmakers lay out, machine, fit, and assemble castings and parts to metal or plastic foundry patterns and core molds.
Foundry mold and coremakers make or form wax or sand cores or molds used in the production of metal castings in foundries.
Molding, coremaking, and casting machine setters, operators, and tenders set up or operate metal or plastic molding, casting, or coremaking machines to mold or cast metal or thermoplastic parts or products.
Multiple machine tool setters, operators, and tenders set up or operate more than one type of cutting or forming machine tool or robot.
Welding, soldering, and brazing machine setters, operators, and tenders (including workers who operate laser cutters or laser-beam machines) set up or operate welding, soldering, or brazing machines or robots that weld, braze, solder, or heat treat metal products, components, or assemblies.
Heat treating equipment setters, operators, and tenders set up or operate heating equipment, such as heat treating furnaces, flame-hardening machines, induction machines, soaking pits, or vacuum equipment, to temper, harden, anneal, or heat-treat metal or plastic objects.
Plating and coating machine setters, operators, and tenders set up or operate plating or coating machines to coat metal or plastic products with zinc, copper, nickel, or some other metal to protect or decorate surfaces (includes electrolytic processes).
A few months of on-the-job training is enough for most workers to learn basic machine operations, but 1 year or more is required to become proficient. Computer-controlled machine workers may need more training.Education
Employers prefer metal and plastic machine workers who have a high school diploma. Prospective workers can improve their employment opportunities by completing high school courses in computer programming and vocational technology, and by gaining a working knowledge of the properties of metals and plastics. Having a sturdy math background, including taking courses in algebra, geometry, trigonometry, and basic statistics, is also useful.
Some community colleges and other schools offer courses and certificate programs in operating metal and plastics machines.Training
Machine operator trainees usually begin by watching and helping experienced workers on the job. Under supervision, they may start by supplying materials, starting and stopping the machines, or by removing finished products. Then they advance to more difficult tasks that operators perform, such as adjusting feed speeds, changing cutting tools, and inspecting a finished product for defects. Eventually, some develop the skills and experience to set up machines and help newer operators.
The complexity of the equipment usually determines the time required to become an operator. Some operators and tenders learn basic machine operations and functions in a few months, but other workers, such as computer-controlled machine tool operators, may need a year or more to become proficient.
Some employers prefer to hire workers who either have completed or are enrolled in a training program.
As the manufacturing process continues to utilize more computerized machinery, knowledge of computer-aided design (CAD), computer-aided manufacturing (CAM), and computer numerically controlled (CNC) machines can be helpful.Licenses, Certifications, and Registrations
Certification can show competence and professionalism and can be helpful for advancement. The National Institute for Metalworking Skills (NIMS) offers certification in numerous metalworking specializations.Advancement
Advancement usually includes higher pay and more responsibilities. With experience and expertise, workers can become trainees for more advanced positions. It is common for machine operators to move into setup or machinery maintenance positions. Setup workers may become industrial machinery mechanics and maintenance workers, or machinists or tool and die makers.
Experienced workers with good communication and analytical skills may move into supervisory positions.Important Qualities
Computer skills. Metal and plastic machine workers must often be able to use programmable devices, computers, and robots on the factory floor.
