EMS Powder Coating Equipment

Powder coating equipment is used to apply a thin layer of powder over a metal surface. This type of coating is applied by an electrostatic process and is a very popular method for finishing metal parts.

This type of equipment can be divided into two main categories: automatic and manual. Automatic booths are more popular because they provide better production rates, but they are also more expensive.

A powder booth is an enclosure in which the powder-coating process takes place. Powder-coating equipment includes an oven where the parts are heated to activate the powder, a gun that sprays or brushes on the powder, a conveyor belt that moves parts through the oven, and cartridge-type guns for applying thicker coatings with less overspray.

Powder coating is a technique that is used to provide a finish to metal parts. This technique has been in use for many years and it is still one of the most popular techniques today.

Powder coating equipment consists of booths, ovens, guns, machines, lines and conveyors. A booth can be either automatic or manual. An automatic booth is more expensive than a manual booth but it is also faster and more efficient.
