Design description of half automatic aluminium profile powdercoating line
1. According to the shape of aluminium profile, we designthe pretreatment to be economical immersion tank type with 6 stageprocessings.
2. After chemical cleaning, the pre-treated workpieces will beconveyed to drying furnace for water removal on their surface. The dryingfurnace 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. Pleasemanually feed them on auto powder painting line. For a better painting result,the spray booth, waster powder recycling system, reciprocator adopts advancedequipments in China through our careful selection. And the spraying guns, bothauto and manual are imported from foreign famous company for a longer servicelife. Then these workpieces will be sent to gas-fired furnace tunnel to letpowder melt into a smooth coating.
