Automated Spray Coating System for Molded Pulp | Precision Internal Coating

1. Composition of Production Line
A complete system includes: an automated conveyor, 6-axis robotic arm with high-precision spray gun, vision positioning system, paint circulation and supply system, and a PLC control cabinet.

2. Product Description
This automated spray coating system is engineered for applying uniform water-based barrier coatings to the interior of complex-shaped molded pulp products. It ensures consistent film thickness and complete coverage, even in deep-draw containers, maximizing material efficiency and product quality.

3. Technical Parameters

4. Application
Ideal for applying moisture and grease barriers to food packaging like bowls, clamshells, and trays with complex geometries.

5. Customization
We offer fully customizable end-effectors and spray paths to match your specific product contours. The paint circulation system can be tailored for different coating viscosities.

6. Feature

• Robotic precision for 100% consistent coverage.

• Up to 40% material savings compared to manual spraying.

• Vision-guided positioning compensates for pulp product dimensional variation.

• Closed-loop paint system maintains coating viscosity and quality.

7. Support and Services
We provide installation & commissioning, robotic path programming training, and a 12-month warranty. 24/7 technical support is available.

8. Packing and Shipping
The system is disassembled into modules, packed in weather-proof wooden cases with custom foam inserts for safe transit.

9. FAQ

• Q: How does it handle different product sizes?

• A: The system can store multiple spray paths. Changeover is quick through recipe selection on the HMI. Customizable quick-change fixtures are available.

• Q: What is the transfer efficiency?

• A: Our advanced spray technology achieves over 85% transfer efficiency, reducing material waste and overspray.
