Product Description

This automatic internal coating spraying equipment is specifically designed for molded pulp industrial packaging (e.g., egg trays, fruit trays, electronic cushioning packaging). It uses programmable robotic arms to evenly apply water-based or solvent-based functional coatings (waterproof, oil-proof, anti-static) onto the inner surface of pulp molded products. The system ensures consistent film thickness, reduces overspray, and increases coating material utilization by up to 40%. Ideal for medium to large-scale production lines.

Technical Parameters

Application

• Molded pulp industrial packaging: electronic product trays, medical device packaging, industrial shock-absorbing liners

• Internal surface coating for water/oil/grease resistance

• Anti-static or anti-corrosion coating for special storage requirements

Customization

Every system is fully customizable: we can adjust robot arm reach, number of spray guns, conveyor width, coating material compatibility, control software interface, and integration with existing production lines. Custom jigs/fixtures for non-standard workpiece shapes are also available.
