• 24-Station Rotary Indexing Table: Precision-engineered core assembly with machined nests for consistent part holding and indexing

• Precision Dosing & Spin Coating Units: Servo-controlled dosing pumps and high-speed spindles for accurate coating application

• Integrated Drying/Curing Tunnel: Conveyorized multi-zone tunnel with IR and forced hot air for solvent evaporation and film curing

• Centralized PLC Control Cabinet & HMI: Touchscreen interface for complete parameter control and production monitoring

• Automatic Unloading & Stacking Unit: Organized collection and stacking of finished coated products

Product Description

This 24-Station Rotary Spin Coating Line is engineered for high-volume, precision application of internal barrier coatings on molded pulp industrial packaging such as electronics protective inserts, automotive component trays, industrial pallets, and heavy-duty packaging containers. Utilizing advanced rotary spin-coating technology, the line securely holds each piece on custom-engineered fixtures and rotates it at controlled speeds while precision nozzles dispense coating, ensuring uniform coverage across all complex interior geometries including deep corners, recesses, and sidewalls. The line integrates dosing, spinning, and curing into one continuous, automated process, significantly enhancing production efficiency, coating quality consistency, and material yield.
