Product Description

This powder coating line is specially designed to provide surface treatment to aluminium profile.

I. Description:

Powder coating is the application of paint in the form of tiny dry particles. Unlike traditional wet spray painting methods, we simply use a clean and efficient electrostatic powder coating process. The parts to be painted are given an electrostatic charge that is opposite to the charge given the powder. As the paint powder is sprayed onto these charged parts, the powder particles are naturally drawn towards this opposite charge. This process yields parts that are uniformly coated with a minimum expenditure of powder, which translates to a superior coating for less money than traditional wet spray methods. After the powder is initially applied, the parts are baked at specific temperatures in curing oven. Inside the oven, the plastic powder instantly turns from its solid powdered phase to liquid phase and finally cures into a solid phase. At the end of the process, there will be a durable plastic coating layer that is bonded directly to the metal.

Design description:
9.1. According to the shape of aluminium profile, we design the pretreatment to be economical immersion tank type with 6 stage processings.
9.2. After chemical cleaning, the pre-treated workpieces will be conveyed to drying furnace for water removal on their surface. The drying furnace is designed being tank type to match with immersion pretreatment tanks, and with a top-door design for easy access of pre-treated workpieces.
9.3. After drying, the workpieces are ready for powder particle adhesion. Please manually feed them on auto powder painting line. For a better painting result, the spray booth, waster powder recycling system, reciprocator adopts advanced equipments in China through our careful selection. And the spraying guns, both auto and manual are imported from foreign famous company for a longer service life. Then these workpieces will be sent to gas-fired furnace tunnel to let powder melt into a smooth coating.
