As a leading innovator in industrial surface finishing, CoatTech (www.spraying-booth.com) is proud to showcase our latest high-efficiency Automatic Spray Pre-Treatment Tunnel, designed to elevate the standard of surface preparation for global manufacturers.
Achieving flawless paint and powder coating adhesion requires meticulous surface preparation. Our newly demonstrated pre-treatment washing booth delivers 360-degree precision cleaning, engineered specifically for seamless integration with continuous automated coating lines and heavy-duty Power and Free Conveyor systems.
Engineered for Maximum Efficiency and Durability
The core of this system lies in its robust construction and eco-conscious engineering. Utilizing premium SUS304 and SUS316 stainless steel, the tunnel is built to withstand harsh chemical environments, including rigorous degreasing, phosphating, and silane treatments. The strategic layout of quick-release adjustable ball nozzles ensures total chemical contact, eliminating blind spots on even the most complex workpieces.
Furthermore, our cascading multi-stage chemical tanks with double-layer stainless steel filtration drastically reduce water consumption and chemical waste, ensuring sustainable, cost-effective operation.
Key Operational Highlights
1.Vapor Containment: Integrated centrifugal exhaust fans at both the entrance and exit silhouettes prevent chemical vapor leakage, maintaining a safe and clean factory environment.
2.Operator Safety: Heavy-duty FRP (Fiberglass Reinforced Plastic) floor gratings provide secure, anti-slip access for routine maintenance and nozzle inspection.
3.Customizable Process Stages: Fully adaptable from 3 to 7+ process stages based on specific chemical supplier requirements and production speeds.
