Compact Single-Station Spin Coating Experimental System for Pulp
Molding – Customizable Coating Parameters & Coating Recovery
Product Description
This single-station spin coating experimental machine is
specifically designed for the pulp molding industry, ideal for
laboratory R&D, small-batch sample testing, and process
optimization. Using high-speed centrifugal spin coating technology,
it applies uniform functional coatings—waterproof, oil-proof, and
biodegradable barrier coatings—onto molded pulp samples such as
plates, bowls, trays, and custom-shaped containers.
Precision Spin Coating: The system achieves uniform coating coverage on complex 3D sample
geometries, including corners, sidewalls, and curved surfaces, with
coating thickness uniformity of ±5%.
Coating Recovery System: Equipped with a coating recovery system, excess coating can be
reused, achieving high utilization (≥90%) and reducing
waste—effectively lowering R&D costs.
Compact & Flexible: The compact design makes it ideal for laboratory environments. The
system supports quick changeover between different samples and
coating formulations, enabling rapid prototyping and process
optimization.
Simple Operation: User-friendly HMI with recipe storage allows easy parameter
adjustment and repeatable results—suitable for both experienced
researchers and operators new to spin coating.
