Product Description
Customizable Modular Spray Coating Line for Pulp Molding
This spray coating production line is engineered for applying uniform, high-performance barrier coatings—waterproof, oil-proof, and heat-resistant—to molded pulp tableware and packaging products. The system uses programmable robotic arms or automated spray guns to evenly apply water-based or solvent-based functional coatings onto the internal and external surfaces of pulp molded products.
Robotic spray systems deliver material transfer efficiency of ≥85%, drastically reducing material waste compared to manual spraying (30-40% efficiency). Customizable spray parameters include gun angle, distance, flow rate, and pattern width to accommodate different product geometries and coating viscosities. The system effectively eliminates pinholes, streaks, and inconsistent film thickness common in manual application.
With intelligent PLC control and recipe-driven operation, the equipment supports fully customizable drying profiles, spray path programs, and product fixture designs to accommodate different product geometries, coating formulations, and production throughputs.

Frequently Asked Questions
Q1: What is the typical production capacity of this spray coating line?
Production capacity ranges from 10-40 cycles per minute depending on configuration (product-dependent). By adding spray guns or increasing conveyor speed, throughput can be scaled to meet production targets. Capacity is fully customizable based on your target production volume and product geometry.
Q2: How does spray coating compare to other coating methods in terms of material efficiency?
Advanced high-transfer-efficiency spray technology achieves ≥85% material transfer efficiency—significantly higher than manual spraying (30-40%). For high-value barrier coatings, this can reduce material costs by up to 40%.
Q3: Can the line be integrated with my existing pulp molding press?
Absolutely. The infeed conveyor height, orientation, and synchronization signals (dry contacts, Ethernet/IP, Profinet) are fully customizable for seamless integration with your existing forming press. We can also integrate robotic pick-and-place for direct transfer from press to the spray coating unit.
