Precision 6-Position Rotary Coating System for Molded Pulp Food Packaging - Uniform Film Thickness Control

Precision 6-Position Rotary Coating System for Molded Pulp Food Packaging - Uniform Film Thickness Control

1. Composition of Production Line
This precision system is a central module in a quality-focused coating line. It comprises a precision-machined 6-position indexing turntable, individual product mandrels/spindles, digitally controlled spray application units, an enclosed process chamber for environment control, a high-efficiency exhaust, and a sophisticated control system with real-time monitoring.

2. Product Description
This precision rotary coating system is built for applications where coating uniformity and exact film thickness are critical (e.g., for high-barrier requirements). Each of the six stations features independent servo-controlled spinning axis, allowing for tailored acceleration, speed, and duration to ensure the coating flows perfectly over complex 3D shapes, eliminating pooling or thin edges.

3. Technical Parameters

4. Application
Ideal for high-end molded pulp food packaging that demands strict barrier properties, such as microwaveable trays, liquid-holding containers, and premium sustainable packaging.

5. Customization
The heart of our system is its customizability. We can engineer the mandrel design for your specific product geometry, integrate vision inspection systems, and create complex spin profiles to match your coating fluid dynamics.

6. Feature

• Ultra-Uniform Coating: Independent servo spindles and precise spray timing guarantee consistent results.

• Complex Shape Mastery: Engineered for complete coverage on deep-draw and multi-angled products.

• Process Repeatability: Digital control and recipe management ensure batch-to-batch consistency.

• Data Logging: Optional SPC data output for quality tracking and traceability.

7. Support and Services
We offer in-depth process development assistance, on-site calibration, and annual maintenance contracts. Technical documentation includes detailed PLC code and mechanical drawings.

8. Packing and Shipping
Critical components like spindles and controls are packed in anti-static and moisture-proof materials. The frame is steel-strapped and crated. We provide detailed packing lists for easy customs clearance.

9. FAQ

• Q: How do you handle coating inside narrow rimmed containers?

  • A: We customize the spray nozzle angle and utilize centrifugal force from precise spinning to draw coating into rims.

• Q: Can thickness be measured in-line?

  • A: Yes, we can integrate non-contact thickness gauges as an optional upgrade.

• Q: What is the maintenance requirement for the precision spindles?

  • A: They are designed for continuous operation with recommended preventative maintenance every 1,000 hours.
