Set up, operate, or tend plating or coating machines to coat metal or plastic products with chromium, zinc, copper, cadmium, nickel, or other metal to protect or decorate surfaces. Includes electrolytic processes.
1) Adjust controls to set temperatures of coating substances and speeds of machines and equipment.
2) Adjust dials to regulate flow of current and voltage supplied to terminals in order to control plating processes.
3) Attach nozzles, position guns, connect hoses, and thread wire in order to set up metal-spraying machines.
4) Determine sizes and compositions of objects to be plated, and amounts of electrical current and time required.
5) Examine completed objects to determine thicknesses of metal deposits, or measure thicknesses by using instruments such as micrometers.
6) Immerse objects to be coated or plated into cleaning solutions, or spray objects with conductive solutions to prepare them for plating.
7) Position and feed materials into processing machines, by hand or by using automated equipment.
8) Immerse workpieces in coating solutions or liquid metal or plastic for specified times.

9) Inspect coated or plated areas for defects such as air bubbles or uneven coverage.
10) Measure and set stops, rolls, brushes, and guides on automatic feeders and conveying equipment or coating machines, using micrometers, rules, and hand tools.
11) Measure, mark, and mask areas to be excluded from plating.
12) Mix and test solutions, and turn valves to fill tanks with solutions.
13) Monitor and measure thicknesses of electroplating on component parts in order to verify conformance to specifications, using micrometers.
14) Observe gauges to ensure that machines are operating properly; make adjustments or stop machines when problems occur.
15) Place plated or coated materials on racks and transfer them to ovens to dry for specified periods of time.
16) Position objects to be plated in frames, or suspend them from positive or negative terminals of power supplies.
17) Read production schedules to determine setups of equipment and machines.
18) Remove excess materials or impurities from objects, using air hoses or grinding machines.
19) Remove objects from solutions at periodic intervals and observe objects to verify conformance to specifications.
20) Rinse coated objects in cleansing liquids; then dry them with cloths, centrifugal driers, or by tumbling in sawdust-filled barrels.
21) Set up, operate, or tend plating or coating machines to coat metal or plastic products with chromium, zinc, copper, cadmium, nickel, or other metal to protect or decorate surfaces.
22) Spray coating in specified patterns according to instructions.
23) Suspend objects such as parts or molds from cathode rods (negative terminals), and immerse objects in plating solutions.
24) Suspend sticks or pieces of plating metal from anodes (positive terminals) and immerse metal in plating solutions.
25) Charge furnaces.
26) Clean and maintain equipment, using water hoses and scrapers.
27) Clean workpieces, using wire brushes.
28) Cut metal or other materials, using shears or band saws.
29) Install gears and holding devices on conveyor equipment.
30) Maintain production records.
31) Measure or weigh materials, using rulers, calculators, and scales.
32) Operate hoists to place workpieces onto machine feed carriages or spindles.
33) Operate sandblasting equipment to roughen and clean surfaces of workpieces.
34) Perform equipment maintenance such as cleaning tanks and lubricating moving parts of conveyors.
35) Plate small objects such as nuts or bolts, using motor-driven barrels.
36) Position containers to receive parts, and load or unload materials in containers, using dollies or handtrucks.
37) Preheat workpieces in ovens.
38) Replace worn parts and adjust equipment components, using hand tools.
39) Test machinery to ensure that it is operating properly.
