Product Description

Our Single-Station Spin Coating Equipment is a precision-engineered system specifically designed for applying uniform functional coatings to the internal surfaces of pulp molded meal containers, such as bowls, plates, trays, lunch boxes, and cups. It is the ideal solution for research & development, prototyping, small-batch production, and coating formula optimization.

The machine utilizes advanced spin-coating technology: a pulp molded product is securely held on a custom-engineered fixture or vacuum chuck within the coating chamber . A precision dispense system applies a controlled amount of coating (water-based, bio-polymer, or barrier coating) onto the product's internal surface. The fixture then rotates at programmable speeds, and the centrifugal force generated spreads the coating evenly across all complex interior geometries, including deep corners and sidewalls, creating a seamless, pinhole-free barrier .

This process ensures:

• Complete Coverage: Even on intricate 3D shapes with recesses and undercuts.

• Precise Control: Coating weight and thickness can be accurately controlled (typically 1-50 microns).

• Minimal Waste: Excess coating is spun off and can be collected and recycled, significantly reducing material consumption .

The system is designed for bench-top or floor-standing installation and is fully customizable to handle various product shapes, sizes, and coating materials.

FAQ

Q1: Can this single-station spin coater handle irregularly shaped pulp molded products like deep bowls or complex trays?
A: 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?
A: 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?
A: The fluid path is designed for easy cleaning. The dispense system uses disposable or easily cleanable components (such as syringes and tubing), 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?
A: 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 (sometimes via an optional vapor hood) is an important part of the process development conducted on the machine .

Q5: Can I export process data for documentation and analysis?
A: Yes. Most models include a USB port or Ethernet connection to export run recipes and actual performance data (speed vs. time) for comprehensive R&D documentation and analysis .

Q6: How do I create a fixture for my unique pulp molded shape?
A: We can design and manufacture fixtures based on your 3D CAD model or physical sample. Simply send us your product specifications, and our engineering team will develop a customized holding solution. Alternatively, the standard vacuum chuck can often be adapted with soft pads or custom inserts .

Q7: What is the typical lead time for a system with a custom fixture?
A: Lead time for a standard system is typically 30-45 days. Adding a custom-designed fixture typically adds 2-4 weeks for design, manufacturing, and testing .
