Powder Coating Equipment
Powder coating is one of the fastest growing sectors in the industrial finishing market. The technology and the innovations in the powder products and curing ovens, has lead to more companies investing in equipment for in-house production. Powder enjoys a tremendous advantage over liquid products. There are no special permit regulations for powder coating. The powder coating finish is more durable. The disadvantage is that powder coating requires a curing oven.
Similar to electrostatic paint system, the powder is negatively charged as it enters the gun, parts are grounded to attract the powder, providing good wrap around characteristics and excellent transfer efficiency.
Manual Powder Coating Systems are available in two versions: box feed and hopper feed unit.
Box feed units are common in applications that require numerous color changes. Simply flush color from the pump and media hose with the built in cleaning features, change out the boxes and you are ready to apply the new color. Box feed carts are equipped with an adjustable vibrating table and fluidized tube to keep the powder free flowing.
Hopper feed units are used for higher production and/or applications that do not have color changes. The hopper itself is fluidized to prevent powder from packing and maintain free-flowing properties. Hopper feed systems can be mounted on a cart or stationary for higher production flow-through systems. Hopper feed units can also be incorporated with a powder recovery/reclaim system.
Powder Coating Guns are available in manual and automatic versions. Manual guns are lightweight and have integrated controls to allow the operator to change powder flow rates and to adjust the electrostatic charge, based on the parts to be coated. No need to stop production and leave the booth to make adjustment at the main control box. Some guns can be pre-programmed to deliver exact voltage and powder flow combination to maximize performance. Automatic guns and powder bells can deliver the most consistent and highest quality finishes.
The control box on portable units will be mounted on the cart and for stationary application it can be wall-mounted.
