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

Tasks

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

Interests

  • Realistic - Realistic occupations frequently involve work activities that include practical, hands-on problems and solutions. They often deal with plants, animals, and real-world materials like wood, tools, and machinery. Many of the occupations require working outside, and do not involve a lot of paperwork or working closely with others.
  • Investigative - Investigative occupations frequently involve working with ideas, and require an extensive amount of thinking. These occupations can involve searching for facts and figuring out problems mentally.
  • Conventional - Conventional occupations frequently involve following set procedures and routines. These occupations can include working with data and details more than with ideas. Usually there is a clear line of authority to follow.

Education, Training, Experience

  • Education - These occupations usually require a high school diploma.
  • Training - Employees in these occupations need anywhere from a few months to one year of working with experienced employees. A recognized apprenticeship program may be associated with these occupations.
  • Experience - Some previous work-related skill, knowledge, or experience is usually needed. For example, a teller would benefit from experience working directly with the public.

Knowledge

  • Production and Processing - Knowledge of raw materials, production processes, quality control, costs, and other techniques for maximizing the effective manufacture and distribution of goods.
  • Mechanical - Knowledge of machines and tools, including their designs, uses, repair, and maintenance.

Skills

  • Operation Monitoring - Watching gauges, dials, or other indicators to make sure a machine is working properly.
  • Operation and Control - Controlling operations of equipment or systems.
