    • Measure and visually inspect products for surface and dimension defects to ensure conformance to specifications, using precision measuring instruments.
    • Observe continuous operation of automatic machines to ensure that products meet specifications and to detect jams or malfunctions, making adjustments as necessary.
    • Set up, operate, or tend metal or plastic molding, casting, or coremaking machines to mold or cast metal or thermoplastic parts or products.
    • Turn valves and dials of machines to regulate pressure, temperature, and speed and feed rates, and to set cycle times.
    • 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.
    • Connect water hoses to cooling systems of dies, using hand tools.
    • Cool products after processing to prevent distortion.
    • Remove parts, such as dies, from machines after production runs are finished.
    • Operate hoists to position dies or patterns on foundry floors.
    • Install dies onto machines or presses and coat dies with parting agents, according to work order specifications.
    • Unload finished products from conveyor belts, pack them in containers, and place containers in warehouses.
    • Perform maintenance work such as cleaning and oiling machines.
    • Remove finished or cured products from dies or molds, using hand tools, air hoses, and other equipment, stamping identifying information on products when necessary.
    • Obtain and move specified patterns to work stations, manually or using hoists, and secure patterns to machines, using wrenches.
    • Select and install blades, tools, or other attachments for each operation.
    • Repair or replace damaged molds, pipes, belts, chains, or other equipment, using hand tools, hand-powered presses, or jib cranes.
    • Inventory and record quantities of materials and finished products, requisitioning additional supplies as necessary.
    • Select coolants and lubricants, and start their flow.
    • Adjust equipment and workpiece holding fixtures, such as mold frames, tubs, and cutting tables, to ensure proper functioning.
    • Maintain inventories of materials.
    • Position and secure workpieces on machines, and start feeding mechanisms.
    • Trim excess material from parts, using knives, and grind scrap plastic into powder for reuse.
    • Smooth and clean inner surfaces of molds, using brushes, scrapers, air hoses, or grinding wheels, and fill imperfections with refractory material.
    • Mix and measure compounds, or weigh premixed compounds, and dump them into machine tubs, cavities, or molds.
    • Spray, smoke, or coat molds with compounds to lubricate or insulate molds, using acetylene torches or sprayers.
    • Preheat tools, dies, plastic materials, or patterns, using blowtorches or other equipment.
    • Pour or load metal or sand into melting pots, furnaces, molds, or hoppers, using shovels, ladles, or machines.
    • Clamp metal and plywood strips around dies or patterns to form molds.
    • Pull level and toggle latches to fill molds, to regulate tension on sheeting, and to release mold covers.
    • Skim or pour dross, slag, or impurities from molten metal, using ladles, rakes, hoes, spatulas, or spoons.
    • Shape molds to specified contours, using sand, and trowels and related tools.
    • Assemble shell halves, patterns, and foundry flasks, and reinforce core boxes, using glue, clamps, wire, bolts, rams, or machines.
