Compact Benchtop Spin Coating Machine with Programmable Speed, Data Logging, and Customizable for Small-Batch Pulp Molding
Product Description
This precision-engineered single-station spin coating system is specifically designed for applying uniform functional coatings—including waterproof, oil-proof, and heat-resistant barrier coatings—to the internal surfaces of molded pulp products such as meal containers, bowls, plates, trays, and cups.
The machine utilizes advanced spin-coating technology where a molded pulp product is securely held on a custom-engineered fixture within the coating chamber. A precision dispense system applies controlled amounts of coating material, then the fixture rotates at programmable speeds (100-10,000 RPM), using centrifugal force to spread the coating evenly across all complex interior geometries.
Unlike spray coating methods, spin coating delivers complete coverage on intricate 3D shapes while achieving coating transfer efficiency greater than 90%, significantly reducing material waste for high-value barrier materials.

Frequently Asked Questions
Q1:Can this single-station spin coater handle irregularly shaped pulp molded products like deep bowls or complex trays?
Yes, absolutely. This is its primary function. The key is a customized vacuum fixture designed specifically to hold your unique 3D mold geometry securely during high-speed rotation. The spin coating process effectively coats all internal contours, including deep corners and sidewalls.
Q2:What is the typical coating thickness range achievable?
Coating thickness depends on several factors including material viscosity, spin speed, and solids content. Typically, the system can achieve uniform films from 1 to 50 microns. Process development using this machine will determine the exact parameters required for your target thickness.
Q3:How do I clean the system between different coating materials?
The fluid path is designed for easy cleaning. The dispense system uses disposable or easily cleanable components, and the fixture/chuck surface is wipe-clean. Detailed cleaning procedures are outlined in the user manual.
Q4:Is the machine suitable for water-based bio-polymer coatings?
Absolutely. The system is compatible with a wide range of coatings including water-based, solvent-based, and bio-polymer formulations. For water-based coatings, controlling drying speed is an important part of the process development.
