Painting and Coating Machine Operators
Published:2009/7/23 Browse Views:6124
Painting and coating machine operators control the machinery and equipment that applies these paints and coatings to a wide range of manufactured products. These workers use several basic methods to apply paints and coatings to manufactured articles. For example, dippers immerse racks or baskets of articles in vats of paint, liquid plastic, or other solutions using a power hoist. Tumbling barrel painters deposit articles of porous materials in a barrel of paint, varnish, or other coating, which is then rotated to insure thorough coverage.
Commonly, paints and coatings are applied by spraying the article with a solution. Spray-machine operators use spray guns to coat metal, wood, ceramic, fabric, paper, and food products with paint and other coating solutions. Following a formula, operators fill the equipment's tanks with a mixture of paints or chemicals, adding prescribed amounts or proportions. They screw nozzles onto the spray guns and adjust them to obtain the proper dispersion of the spray, and hold or position the guns to direct the spray onto the article. The pressure of the spray is regulated by adjusting valves. Operators check the flow and viscosity of the paint or solution and visually inspect the quality of the coating. They may also regulate the temperature and air circulation in drying ovens.
