Product Description
High-Output Dual-Station Spin Coater for Water/Oil Barrier Coating of Pulp Molded Tableware
Production Line Overview
This semi-automated, compact line is centered around the dual-station coater for efficient batch processing:
- Manual/Robotic Loading Station: Operators or robotic arm place pulp products onto rotating chucks
- Dual-Station Spin Coating Unit: Core assembly with two independent high-speed rotary chucks and precision dosing systems
- Integrated Drying Rack or Conveyor (Optional): Timed conveyor or rotating rack for drying/curing area transfer
- Control Cabinet with HMI: Centralized control panel for operating both stations and managing parameters
Product Description
Our Dual-Station Spin Coater is engineered for high-efficiency application of internal barrier coatings on pulp molded tableware. Two independently controlled workstations allow continuous operation - one station can be loaded/unloaded while the other actively coats, dramatically reducing idle time and maximizing output. Precision servo-controlled spinning and dosing ensure uniform, pinhole-free film application with exceptional material utilization and repeatability.

Frequently Asked Questions
Q1: What is the main advantage of a dual-station over two single-station machines?
A: A dual-station machine shares one control system, one frame, and often one operator, resulting in lower total investment, smaller footprint, and higher operational efficiency due to reduced waiting time between cycles.
Q2: How uniform is the coating on deep and complex shapes like bowls?
A: For complex 3D shapes, we offer customizable multi-axis tilt or orbital spin chucks (as an option) to ensure the coating liquid reaches all internal surfaces evenly. Standard chucks are best for shallower shapes like plates and trays.
Q3: How quickly can we change over between different products?
A: Changeover is rapid. The operator simply calls a different pre-saved recipe on the HMI and changes the physical chuck fixtures. With quick-release chucks, this can be done in minutes.
Q4: Can this machine apply coatings to the external surface as well?
A: The standard configuration is for internal coating. For external coating, a different chuck design and drip-collection system would be required, which can be discussed as a customization.
Q5: Do you provide samples coated with our own products?
A: Yes. We offer a sample coating service. You can send us your pulp products and target coating material, and we will run trials and provide a process report and coated samples for your evaluation.
