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.

We have been running this 24‑station spin coating production line for some time for our molded pulp product mass production. The whole line works stably in continuous‑shift operation. With 24 working stations, it greatly lifts our production throughput. The spin‑coating process delivers consistent coating thickness on pulp trays and bowls, even for complex curved surfaces. The PLC touch‑screen system stores multiple process recipes. Our operators can switch between different products quickly without complicated re‑setting. The integrated conveyor, spin‑coating units and drying tunnel work in good synchronization. Material waste is much lower compared with manual spraying. Daily maintenance is straightforward. We only need regular cleaning of the coating stations. The machine meets our mass‑production expectations, and we are satisfied with its overall performance.
