Metal or Plastic Machine Worker

Metal and plastic machine workers set up and operate equipment that cuts, shapes, and forms metal and plastic materials or pieces.

Metal and plastic machine workers typically do the following:

• Set up and adjust machines according to blueprints
• Monitor machines status to ensure proper functioning
• Insert material into machines, either manually or using material handling equipment
• Operate shaping and forming equipment, such as metal or plastic molding, casting, or coremaking machines
• Operate stock removal metalworking machines, such as lathes or mills
• Adjust machine settings for temperature, cycle times, and speed and feed rates
• Remove finished products and document output in a database
• Measure, test, and inspect finished workpieces according to blueprints
• Observe and adjust or replace dull or damaged cutting tools

Injuries and Illnesses

These workers often operate powerful, high-speed machines that can be dangerous and must observe safety rules. Operators usually wear protective equipment, such as safety glasses, earplugs, and steel-toed boots, to guard against flying particles of metal or plastic, machine noise, and heavy objects, respectively.

Other required safety equipment varies by work setting and machine. For example, respirators are common for those in the plastics industry who work near materials that emit dangerous fumes or dust.

Welding, soldering, and brazing machine setters, operators, and tenders have one of the highest rates of injuries and illnesses of all occupations.

Work Schedules

Most metal and plastic machine workers are employed full time. Some work more than 40 hours per week. Because many manufacturers run their machinery for extended periods, evening and weekend work is also common.

Metal and plastic workers typically need a high school diploma to enter the occupation and receive 1 year of on-the-job training. Computer numerically controlled (CNC) tool programmers typically need postsecondary education.

Education

Although metal and plastic machine workers typically need a high school diploma, CNC tool programmers usually need coursework beyond high school. Some community colleges and other schools offer courses and certificate programs in operating metal and plastics machines including CNC programming.

For metal and plastic machine workers, high school classes in computer programming, math, and vocational technology may be useful.

Training

Machine operator trainees usually begin by watching and helping experienced workers on the job. Under supervision, they may supply materials, start and stop the machines, or remove finished products. Then, they advance to operators’ more difficult tasks, such as adjusting feeds and speeds, replacing tools, and measuring finished products for conformance. Eventually, some operators develop the skills and experience to set up machines.

The complexity of the equipment usually determines the time required to become an operator. Some operators and tenders are trained on basic machine operations and functions in a few months. Others, such as CNC tool operators, may need training for up to 1 year.

Because of the prevalence of computerized machines in manufacturing, training on computer-aided design (CAD), computer-aided manufacturing (CAM), and CNC equipment may be helpful.

Licenses, Certifications, and Registrations

Certification can show competence and can be helpful for advancement. The National Institute for Metalworking Skills  (NIMS) offers certification in numerous metalworking specializations.

Advancement

With skill and experience, workers may advance to positions that offer higher pay and more responsibility. It is common for machine operators to move into setup or machinery maintenance positions. Setup workers may become industrial machinery mechanics and maintenance workers, machinists, or tool and die makers.

Experienced workers with good communication and analytical skills may advance to supervisory positions.

Metal and plastic machine workers typically have an interest in the Building, Thinking and Organizing interest areas, according to the Holland Code framework. The Building interest area indicates a focus on working with tools and machines, and making or fixing practical things. The Thinking interest area indicates a focus on researching, investigating, and increasing the understanding of natural laws. The Organizing interest area indicates a focus on working with information and processes to keep things arranged in orderly systems.

If you are not sure whether you have a Building or Thinking or Organizing interest which might fit with a career as a metal and plastic machine worker, you can take a career test to measure your interests.

Metal and plastic machine workers should also possess the following specific qualities:

Computer skills. Employers who have modern technology systems require that metal and plastic machine workers be able to use programmable devices, computers, and robots on the factory floor.

Dexterity. Precise hand movements are necessary in order to produce workpieces that meet exact specifications. Those who work in metal and plastic machined goods manufacturing must have good manual dexterity in order to make the necessary shapes, cuts, and edges that designs require.

Mechanical skills. Although modern technology has brought a lot of computer-based systems to this occupation, workers still 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. Although most material handling is done using automated systems, some metal and plastic machine workers must be strong enough to guide and load heavy and bulky parts and materials into machines.

The median annual wage for metal and plastic machine workers was $38,040 in May 2021. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less.

Most metal and plastic machine workers are employed full time. Some work more than 40 hours per week. Because many manufacturers run their machinery for extended periods, evening and weekend work also is common.

Overall employment of metal and plastic machine workers is projected to decline 5 percent from 2021 to 2031.

Despite declining employment, about 101,700 openings for metal and plastic machine workers are projected each year, on average, over the decade. All of those openings are expected to result from the need to replace workers who transfer to other occupations or exit the labor force, such as to retire. 

Employment

Projected employment of metal and plastic machine workers varies by occupation (see table).

One of the most important factors influencing employment of these workers is the use of laborsaving machinery. Many firms are continuing to expand the use of technologies, such as computer numerically controlled (CNC) tools and robots, to improve quality and lower production costs. The use of CNC equipment requires CNC tool programmers instead of machine setters, operators, and tenders. Therefore, demand for most manual tool operators and tenders is likely to be reduced, while demand for CNC tool programmers is expected to be strong.

Employment of metal and plastic machine workers also is affected by the demand for the parts they produce. Both plastic and metal manufacturing industries face foreign competition that limits the orders for parts produced in this country. Changes in the cost of operations in the United States and abroad may encourage some manufacturers to bring back production that was previously sent offshore. However, new facilities in the United States will likely incorporate more automation technologies, requiring less labor overall.
