Design description of half automatic aluminium profile powder coating line
1. According to the shape of aluminium profile, we design the pretreatment to be economical immersion tank type with 6 stage processings.
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.
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.
