Product Description
Smart 24-Station Spin Coating Line for Water/Oil Barrier Coating of Pulp Molded Tableware
This fully automated, inline production system is engineered for high-volume, precision application of internal barrier coatings on pulp-molded tableware such as plates, bowls, trays, and food containers.
Production Line Composition
- Automated Infeed Conveyor: Syncs with upstream molding press to automatically load unfinished pulp products
- 24-Station Rotary Indexing Table: Core assembly with precisely machined nests for consistent part holding and indexing
- Pre-Coating Treatment Zone (Optional): Integrated plasma or flame treater station to enhance coating adhesion
- Precision Dosing & Spin Coating Units: 24 independent sets of servo-controlled dosing pumps and high-speed spindles
- Integrated Drying/Curing Tunnel: Conveyorized tunnel with staged heating (IR/hot air) for solvent evaporation and film curing
- Centralized Control Cabinet & HMI: PLC, drives, and touchscreen interface for complete parameter control and monitoring
- Outfeed & Quality Inspection Conveyor

Frequently Asked Questions
Q1: What is the main advantage of spin coating over spray coating for pulp molds?
A: Spin coating provides far superior coating uniformity inside complex contours, uses material more efficiently (>90% transfer vs. ~50-70% for spray), and creates a pinhole-free film with less coating weight.
Q2: Can this line handle different sizes and shapes of products?
A: Yes, through customization. The line is designed for quick changeovers. Different product shapes require corresponding custom machined nesting tools, which we provide.
Q3: What is the lead time for such a line?
A: For a standard 24-station line, the lead time is approximately 90-120 days after order confirmation. Lead time for heavily customized configurations will be confirmed during the engineering review.
Q4: How do you ensure the coating adheres well to the pulp surface?
A: We offer an integrated pre-treatment station (plasma or flame) as an optional customization. This activates the pulp surface, dramatically improving coating wetting and adhesion for a robust final product.
Q5: Do you provide a trial or sample coating service?
A: Yes. We can arrange sample coating trials at our facility using your specific pulp products and coating materials to validate results before you purchase. Please contact us to discuss details.
