Design  description for LPG cylinder powder painting line
1. According to the shape of LPG tank, we design the pretreatment to be economical  immersion tank type with 6 stage processings.
2. After chemical cleaning, he 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.
