24-Station Rotary Coating Line for Internal Coating of Pulp Molding | High-Volume Automated Production System

24-Station Rotary Coating Line for Internal Coating of Pulp Molding | High-Volume Automated Production System

Product Description:
This fully automated 24-station rotary coating production line is engineered for the high-efficiency internal application of functional barrier coatings, primers, or decorative finishes to three-dimensional pulp molded products. Utilizing a precision rotary indexing system, it ensures each product receives identical, controlled coating coverage and thickness in a continuous, synchronized process. The system is highly customizable to accommodate a wide range of product sizes and shapes, making it ideal for large-scale manufacturing of items like food containers, industrial packaging, and tableware.

Composition of Production Line:

• Automated Infeed Conveyor & Product Orienter

• Customizable 24-Station Rotary Indexing Table with Precision Turntable

• Individual Coating Head per Station (Dipping, Spraying, or Precision Dispensing)

• Centralized Coating Material Supply & Recirculation System

• Integrated Drip/Drain Station

• In-process Drying/Curing Modules between Stations (Optional IR/UV/Hot Air)

• Quality Inspection Station (Optional Vision System)

• Automated Outfeed & Sorting Conveyor

• Centralized PLC Control Panel with Industrial HMI

Technical Parameters:

Application:
Designed for high-volume internal coating of pulp molded products such as:

• Food service items (plates, bowls, clamshells, cups)

• Egg cartons and fruit trays

• Industrial protective packaging

• Premium gift packaging

Customization:
The entire line is built to order with extensive customization options. These include the number of stations, the specific coating mechanism per station (to handle different product geometries), the integration and type of drying systems between steps, material handling fixtures, and full integration with upstream (forming) and downstream (packaging) equipment.

Feature:

• High Throughput & Consistency: 24-station parallel processing ensures identical coating quality for every piece at high speed.

• Reduced Material Waste: Precise, controlled application minimizes overspray and coating usage.

• Flexible Production: Quick-change fixtures and PLC recipes allow for running different product types with minimal downtime.

• Closed-Loop Control: Optional viscosity and level sensors maintain coating material consistency.

• Rugged Construction: Built for 24/7 operation in humid industrial environments.

Support and Services:
We provide turnkey support including factory acceptance testing (FAT), on-site installation & commissioning, comprehensive operator & maintenance training, process optimization, annual service contracts, and a global spare parts network.

Packing and Shipping:
The line is disassembled into major modular components (frame, table, control cabinet, etc.). Each module is securely packed in weatherproof, shock-absorbing wooden crates suitable for ocean freight. Shipping terms are negotiable (FOB, CIF, DDP).

FAQ:

• Q: Can this line handle different sizes of pulp molded products simultaneously?

  • A: Not simultaneously. However, through customizable quick-change fixtures and saved PLC recipes, the line can be rapidly converted between different product families in a batch production mode.

• Q: How is coating uniformity ensured across all 24 stations?

  • A: Each station is equipped with its own individually calibrated coating head and fluid control system, all supplied from a common, agitation-equipped reservoir to ensure material consistency. The rotary indexing mechanism ensures identical dwell and process time at each station.

• Q: What about curing? Is it part of the line?

  • A: Curing can be integrated. We can design the line with intermediate drying stations (e.g., between coating steps) and a final curing tunnel as part of the customized layout, creating a complete “coated-and-dried” output.

• Q: How is maintenance handled for so many coating heads?

  • A: The design emphasizes modularity and easy access. Heads can be individually serviced or replaced without stopping the entire line. We provide detailed maintenance manuals and training.

• Q: What is the typical project timeline from order to commissioning?

  • A: For a customized 24-station line, the timeline typically ranges from 20 to 30 weeks, covering detailed engineering, manufacturing, factory testing, shipping, and on-site installation. A precise schedule is provided upon project finalization.
