Frequently Asked Questions
Q1: What is the main advantage of spin coating over spray coating for pulp molds?
A: Spin coating provides far superior coating uniformity inside complex contours, uses material more efficiently (>90% transfer vs. ~50-70% for spray), and creates a pinhole-free film with less coating weight.
Q2: Can this line handle different sizes and shapes of products?
A: Yes, through customization. The line is designed for quick changeovers. Different product shapes require corresponding custom machined nesting tools, which we provide.
Q3: What is the lead time for such a line?
A: For a standard 24-station line, the lead time is approximately 90-120 days after order confirmation. Lead time for heavily customized configurations will be confirmed during the engineering review.
Q4: How do you ensure the coating adheres well to the pulp surface?
A: We offer an integrated pre-treatment station (plasma or flame) as an optional customization. This activates the pulp surface, dramatically improving coating wetting and adhesion for a robust final product.
Q5: Do you provide a trial or sample coating service?
A: Yes. We can arrange sample coating trials at our facility using your specific pulp products and coating materials to validate results before you purchase. Please contact us to discuss details.
