When plastic injection molded parts are pulled off the mold, the surface of the product is charged with static electricity. This static electricity from the part draws dust particles from the air to stick onto the surface of the product.During a painting process, such dust may cause painting defects. The dust may show up on the finished coat and the surface may not be evenly painted (or coated).To avoid such defects, Vessel’s BBZ-E nozzle-type ion gun can be used to neutralize and eliminate static electricity, and to effectively clean the surface of the part before the general painting or coating process.Unlike the Vessel BBZ-E ion gun, the traditional static eliminating system would consist of an air gun to discharge ionized air for neutralization, a large transformer to generate high voltage, and a high-voltage cable to connect these components. However, there are some issues with this type of setup. For instance, a large bulky external transformer takes up valuable space and cannot be installed at various work sites. Also, since the cable is constantly bending, it’s prone to break or disconnect which may cause an electric shock.Other Surface Cleaning Examples
