Automatic Reciprocating Spray Coating Machine with Customizable Spray Guns for

This advanced automatic reciprocating spray coating machine is specifically engineered for the pulp molding industry. It utilizes high-precision reciprocating spray guns to apply uniform functional coatings—waterproof, oil-proof, and biodegradable barrier coatings—onto molded pulp products such as tableware, food containers, and industrial packaging. The system combines automatic loading, precision reciprocating spray coating, and integrated drying in a single continuous production flow.

• Precision Reciprocating Spray Coating: High-precision spray guns mounted on a reciprocating mechanism move back and forth across the product surface, ensuring uniform coating coverage on complex 3D geometries, including corners, sidewalls, and curved surfaces. The system achieves coating thickness uniformity of ±5%.
• High Transfer Efficiency: Advanced spray gun technology with optimized atomization achieves transfer efficiency of up to 85%, significantly reducing coating material consumption.
• Integrated Drying: The production line includes an integrated IR or UV-LED drying tunnel, enabling immediate curing and downstream handling without additional transfer steps.
• Clean & Eco-Friendly: An enclosed spray booth with exhaust and filtration system captures overspray and solvent vapors, ensuring a clean working environment.

• Molded Pulp Tableware: Spray coating waterproof and oil-proof barriers on plates, bowls, trays, clamshell boxes, and cup carriers — uniform coverage on complex 3D geometries.
• Industrial Pulp Packaging: Spray coating protective and anti-static coatings on egg trays, fruit trays, electronic cushioning pads, and industrial corner protectors.
• Agricultural Products: Spray coating biodegradable barrier coatings on seedling pots, horticultural trays, and planting containers.
• Premium Molded Products: Spray coating aesthetic and functional coatings on medical device trays, cosmetic packaging inserts, and custom-shaped containers.
• High-Volume Production Lines: Continuous reciprocating spray coating for large-scale manufacturing where production flexibility and coating quality are critical.
