1.Brief introduction
Vertical Pretreatment Washer-Spray pretreatment
This system for online cleaning of consists of a tunnel mounted on tanks, components piping pump and nozzles etc. The design is based on conveyor speed, article profile & pretreatment timing. The spray tunnel is designed on a completely weld less system. This eliminates chances of leakage. Special arrangements ensure leakless locking between the zones.
The heating system is designed to give the best heat transfer and consume minimum of the tank volume. The oil skimmer is incorporated as a standard part of every system to keep the cost of refilling low by getting the most out of the chemicals.
2.Production Procedure:
1. Spraying pretreatment → 2. Drying oven → 3. Uploading → 4. Workpieces into spray booth→ 5. After spraying the workpieces will go into the curing oven(20~25min, 180~200ºC)→ 6. Go out of the oven, and natural cooling→ 7. Unloading workpieces
