  • 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.
