Systèmes de prétraitement
Pretreatment is the foundation of coating adhesion and appearance stability. We match immersion, spray, or basket-hanging pretreatment solutions according to workpiece structure, dead corners, hollow sections, surface oil contamination, and automation requirements.
Préadaptation par immersion
Caractéristiques :
- Le prétraitement par immersion réalise le processus en immergeant complètement la pièce dans le bac de traitement.
- Avantages :Low energy consumption, with certain advantages for products with many dead corners or hollow pipe structures.
Prétraitement par pulvérisation
Caractéristiques :
- Spray pretreatment is convenient and efficient, and can support automated operation.
- Avantages :It can support fully automated line operation, save labor, reduce treatment liquid consumption, maintain stable quality, and avoid secondary pollution.
Basket-Hanging Pretreatment
Caractéristiques :
- Basket-hanging pretreatment is designed for complex and diverse workpieces. It can handle workpieces that automatic spray pretreatment cannot process, offering a wide application range.
- Avantages :It can clean large, irregular, and hollow products and is suitable for a wide range of industries.
Powder Booth & Powder Recovery System
The powder booth and powder recovery system directly affect powder utilization, workshop cleanliness, and color change efficiency. Ketu Machinery can configure cyclone recovery, cartridge filter recovery, or fast color change booth solutions according to the number of colors, color change frequency, powder type, and production rhythm.

Features of the Water Curtain Spray Booth:
- The water curtain spray booth directs overspray paint particles into the water tank or onto the water curtain surface. Odor and small amounts of unabsorbed paint mist generated during spraying pass through multiple water curtain layers for filtration, then are discharged by the exhaust fan to environmental treatment equipment. This helps purify the spraying work environment, protect operator health, and improve the surface smoothness of painted workpieces.
Avantages :
- The water curtain spray booth is easy to operate, stable, and safe to use. It is widely used in paint spraying workshops across many industries.
