High-Speed 24-Station Rotary Spin Coating Line for Pulp Molding Food Tray Waterproofing

High-Speed 24-Station Rotary Spin Coating Line for Pulp Molding Food Tray Waterproofing

• Composition of Production Line:
  This integrated system comprises an automatic loading carousel, 24-station rotary indexing table with individual product holders, integrated spin coating units (stationary spray gun + rotating workpiece), double-stage IR pre-drying tunnels, main hot air drying area, cooling zone, and automatic unloading conveyor.

• Product Description:
  Our high-capacity 24-station rotary spin coating line is engineered for mass production of waterproof and oil-proof food containers, such as clamshells, plates, and bowls. The spin coating technology ensures a uniform, thin internal coating on complex 3D shapes, achieving complete coverage with minimal material usage. The multi-stage drying system ensures thorough curing without deformation of the pulp substrate.

• Technical Parameters:

• Application:
  Applying water-resistant (PFAS-free) or oil-resistant coatings to disposable food service products like takeaway containers, paper bowls, and snack trays.

• Customization:
  This line can be customized with different spray gun types for specific coatings, oven length and heating power based on your cure requirements, and fixture designs to hold your specific products securely.

• Feature:

  • High Uniformity: Spin coating ensures consistent film thickness inside complex 3D shapes.

  • High Efficiency: 24-station continuous operation maximizes throughput.

  • Material Saving: Precision application reduces coating waste by over 30% compared to traditional spray.

  • Gentle Drying: Multi-stage process prevents bubbling or warping of delicate pulp products.

• Support and Services:
  Turnkey installation, process parameter setup for your specific coating, comprehensive operator training, and a one-year warranty on parts.

• Packing and Shipping:
  The line is shipped in major modules (coating section, oven, conveyor) pre-assembled on frames. All parts are crated and seaworthy for international shipping.

• FAQ:
  Q: How does spin coating provide better coverage than traditional spraying for deep-draw containers?
  A: The combination of a precisely timed spray and the rapid rotation of the product uses centrifugal force to spread the coating thinly and evenly across the entire interior surface, including steep walls and corners, eliminating pooling and ensuring complete coverage.
