Frequently Asked Questions
What is the main advantage of spin coating compared to traditional spray coating for molded pulp?
Spin coating uses centrifugal force to create an extremely uniform, thin film that perfectly conforms to complex interior shapes. It ensures seamless coverage in corners where traditional spray might miss, resulting in superior barrier properties with more precise control over coating weight.
Can this line handle different product shapes (e.g., both square trays and round bowls)?
Yes. The key is the customizable fixture design. We create dedicated fixtures for each product shape. Changeover between products involves swapping the fixtures and loading a different recipe from the PLC, which can be done in minutes.
What types of coatings can be applied with this machine?
The system is compatible with a wide range of functional coatings, including water-based acrylics, PFAS-free oil-barrier coatings, bio-polymer films, and anti-static agents. The fluid path components can be customized to handle specific material viscosities and chemistries.
How is the coating thickness controlled?
Thickness is controlled by several programmable parameters: the rotational speed (RPM) of the spin, the acceleration rate, the volume of coating dispensed, and the viscosity of the material. All these parameters are stored in the PLC for perfect repeatability.
What is the typical lead time for a customized production line?
Lead time depends on the complexity of the customization. After finalizing the design based on your product samples, manufacturing typically takes between 30 to 50 working days, followed by sea freight shipping.
