Dip Coating
The process of dip coating involves the dunking of an object into a tank holding coating material, removing the object, and then giving it time to dry. This process can be divided into three steps. First, at an unvarying speed, the object is submerged into the coating material. Next, while remaining stationary, the object is left in the coating material. And last, at an unvarying speed, the object is removed from the material. The thickness is determined by how quickly or slowly the object is removed.
Dip coating creates products that are corrosion resistant. Dip coating can cover many sized parts and is found in multiple colors and textures. It is used for medical equipment, fitness equipment, tool handles, wire forms, electrical connectors, cushion covers, corrosive areas, handles and many more.
Two types of dip coating include cold dip coating and hot dip coating. Cold dip coating is used mostly for thin coatings of plastisol. In this process, the object is dipped in plastisol without preheating, and then placed in a heated chamber. Hot dip coating is the process in which an object is heated, dipped in plastisol and then placed in a heated chamber where fusion takes place.
