Box-Fed Vs. Hopper-Fed Powder Guns
Many shops that do contract work rely on box-fed manual coating guns. A box-fed gun pulls powder directly from the box that the powder was packaged in by the powder coatings supplier. The box is typically placed on the base of the cart that holds the gun controls. This allows for quick color changes and simple, intuitive operation. The powder is typically fluidized through vibration or air injection. One downside is that the powder media is exposed to the shop environment, so it is easier for the powder to become contaminated or otherwise degraded. A hopper-fed gun conveys the powder from a stainless steel hopper which can be removed from the cart to be refilled or cleaned. Fluidization of the powder is achieved by the use of an integral fluid bed (generally speaking this the preferred method of fluidization vs. vibratory box feed). This coating system is ideal for manual coating in a production environment. We have both box and hopper-fed versions in stock at all times!
