How to Become One
How to Become a Metal or Plastic Machine Worker Metal and plastic machine workers must be able to stand for long periods and perform repetitive work. Metal and plastic workers typically need a high school diploma to enter the occupation and receive 1 year of on-the-job
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.

Job Outlook
Job Outlook Overall employment of metal and plastic machine workers is projected to grow 7 percent from 2025 to 2035, decline. About 78,100 openings for metal and plastic machine workers are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different 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. Additionally, the use of software to create digital and 3D-print prototypes may reduce the need for some of these workers, including patternmakers and model makers. 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.

What They Do
What Metal and Plastic Machine Workers Do
Metal and plastic machine workers set up and operate equipment that cuts, shapes, and forms metal and plastic materials or pieces.
Duties
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
Metal and plastic machine workers operate equipment that creates the parts for consumer products. 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 being either a machine setter or a machine operator and tender.
Machine setters, or setup workers, prepare the machines before production, do test runs, and, if necessary, adjust and make minor repairs to the machinery before and during operation. Computer numerically controlled (CNC) setters upload computer control programs.
After installing the tools into a machine, setup workers often produce the initial batch of goods, inspect the products, and turn over the machine to an operator.
Machine operators and tenders monitor the machinery during production.
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 machine speeds during production. They must periodically inspect the parts that a machine produces to ensure everything works properly, repairing equipment as needed. For example, the parts a machine produces may show defects if the cutting tool inside a machine becomes dull or damaged after extended use. When that happens, it is common for an operator to remove the worn tool and replace it with a new one produced by tool and die makers. Operators may fix minor problems themselves but may have an industrial machinery mechanic fix more serious problems.
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 machines, others are trained to set up or operate a variety of them. Automation often allows machine operators to control multiple machines at the same time.
In addition, 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 range of skills.
The following are examples of types of metal and plastic machine workers:
Computer numerically controlled tool operators operate CNC equipment or robots to perform functions on metal or plastic workpieces.
Computer numerically controlled tool programmers develop computer programs to control the machining or processing of metal or plastic parts by automatic machine tools, equipment, or systems.
