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.

Dexterity. Metal and plastic machine workers who work in metal and plastic machined goods manufacturing use precise hand movements to make the necessary shapes, cuts, and edges that designs require.

Mechanical skills. Metal and plastic machine workers set up and operate machinery. They must be comfortable working with machines and have a good understanding of how the machines and all their parts work.

Physical stamina. Metal and plastic machine workers must be able to stand for long periods and perform repetitive work.

Physical strength. Metal and plastic machine workers must be strong enough to guide and load heavy and bulky parts and materials into machines.
