The newest technique to produce beautiful finishing is powder coating. It is a process of applying a coating without the need to use solvents. This is similar to applying dry paint on the surface. Instead of paint, however, pigmented powder created from aluminum, medium density fiberboards, fusion-bonded epoxy and acrylics are used to produce polymer granules. They are mixed with powder ingredients and pigments to produce the desired color.All of these ingredients are placed in an extruder, rolled flat and then cooled off. It is then broken down into many pieces and milled to produce the powder. The powder is usually applied using a gun with electronic charge. The object is then heated to melt the powder making the finish stick on the surface. It produces a hard, tough and abrasion resistant skin for the object. This is a preferred finishing for metallic objects because it can produce a very smart looking result and can be applied in a wide range of thickness.There are various equipment used in powder coating. One is the gun used to spray the electronically charged powder on to the surface of the object. One type of gun is called the corona charging gun. Electronic power is used to produce a charge on the powder. This gun can be used either internally or externally. Another type of powder coating gun is the tribo charging gun. This gun produces friction between the powder and the gun barrel. It uses friction instead of electricity to produce the electric charge for the powder. A bell charging gun flings the powder from the perimeter of the bell producing the electrical charge on the powder. Whichever gun you use, the end result is the same. To compare and contrast between guns, check out specialized sites on the Web about power coating.Powder Coating provides detailed information on Powder Coating, Powder Coating Equipment, Powder Coating Ovens, Powder Coating Systems and more. Powder Coating is affiliated with Hand Car Wash.
