Before you ever spray any components, parts, or equipment, the best powder coat gun system should be selected. The best scenario is to have a system that will require only minimum manual touch-up. Simple shapes, flat panels or tubes can be effectively coated with corona charging guns. For coating of complex shapes that include areas where some penetration is required, a corona charging gun with FARADAY WAVE technology would be recommended.

If you have ever coated parts with inside corners or complex geometries, then you have more than likely experienced the Faraday cage effect. The Faraday cage acts as an invisible electrical screen that prevents charged powder particles from reaching the internal corners and recesses of various parts. If the powder particles cannot penetrate these areas, then the part will not be completely coated, which can often result in premature corrosion.
Automatic spraying systems involve the use of high quantities of powder and must be controlled to ensure efficiency of its use. Therefore instrumentation is important when producing consistent quality. Wear is also another major factor that should be considered. Large quantities of powder can stress the powder gun parts. The wider the range of useful accessories, the more flexible will be the range of work that can be undertaken. A wide range of accessories are available from Powder Buy the Pound. These help to ensure that the initial investment has a greater return.
