Manufacturing plays a key role in our national economy. The label "Made in America" has come to stand for quality goods, made reliably and efficiently. So each person on the production line has to do their job well. Molding, coremaking, and casting machine setter, as well as operators and tenders for metal and plastic, are each trained to do a specific job.

The setters get the machines ready for operation. They are trained to adjust and set up specific equipment. The tenders operate the machines during production. These are skills that can be learned on the job. They require good hand-eye coordination, the ability to read and follow instructions, and, often, physical strength.

The work can be repetitive, requiring lifting and bending. The workplace can be noisy and distracting. Safety equipment such as earplugs may be required. Global competition, as well as advances in automation will make it more difficult to find this kind of work in the years ahead.

However, while job opportunities may become limited, the high expectations for quality will remain the same. Because even if what you're making is just a small piece of a larger item, the ultimate product is only going to be as reliable as its individual parts.

Set up, operate, or tend metal or plastic molding, casting, or coremaking machines to mold or cast metal or thermoplastic parts or products.

Connect water hoses to cooling systems of dies, using hand tools.

Perform maintenance work such as cleaning and oiling machines.

Remove parts, such as dies, from machines after production runs are finished.

Read specifications, blueprints, and work orders to determine setups, temperatures, and time settings required to mold, form, or cast plastic materials, as well as to plan production sequences.

Observe meters and gauges to verify and record temperatures, pressures, and press-cycle times.

Observe continuous operation of automatic machines to ensure that products meet specifications and to detect jams or malfunctions, making adjustments as necessary.

Turn valves and dials of machines to regulate pressure, temperature, and speed and feed rates, and to set cycle times.

Measure and visually inspect products for surface and dimension defects to ensure conformance to specifications, using precision measuring instruments.

Controlling Machines and Processes Using either control mechanisms or direct physical activity to operate machines or processes (not including computers or vehicles).
Handling and Moving Objects Using hands and arms in handling, installing, positioning, and moving materials, and manipulating things.
Inspecting Equipment, Structures, or Material Inspecting equipment, structures, or materials to identify the cause of errors or other problems or defects.
