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 or in-situ drying) is an important part of the process development.
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 15-25 working days. Adding a custom-designed fixture typically adds 10-15 days for design, manufacturing, and testing.
Q8: What is the warranty period?
A: The standard warranty is 12 months on parts and labor. Consumable items (syringes, tubing, filters) are not covered. Extended warranty options are available upon request.
Q9: Do you provide training for operators?
A: Yes. We provide video-based training materials and live online training sessions. On-site training is also available at an additional cost.
Q10: Can this machine be used for external coating as well?
A: While the machine is optimized for internal coating, it can also coat external surfaces by using a fixture that holds the product from the inside. Please discuss your specific requirements with our engineers for a customized solution.
