6. Design description:
6.1 A ccording to the size of aluminum profiles,we design the pretreatment to be immersion tank type .
6.2 Then the pretreated workpieces will be conveyed to drying oven for water removal on their surface. The drying furnace is of
tank shapewith a top-door design foreasy access of pre-treated workpieces.
6.3 After drying, the workpieces are ready for powder particle adhesion. Please manually feed them on auto powder coating 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.
