1. Composition of the Production Line

This compact, all-in-one R&D unit integrates the core functions of a production line into a single benchtop station:

• Integrated Vacuum Chuck: A powerful, variable-speed vacuum chuck securely holds pulp molded samples (plates, bowls, trays) during the coating process.

• Precision Dispense System: A servo-driven syringe or pump system for accurate coating material deposition.

• High-Speed Spin Motor: The core spindle motor enabling precise rotational speed control for film formation.

• Optional Drying/Curing Module: A compact IR or thermal module attached to the station for inline drying/curing.

• Central Control Panel: Touchscreen HMI (Human-Machine Interface) for programming and controlling all parameters.

2. Product Description

Our Benchtop Lab Spin Coater is an essential R&D tool designed specifically for developing and optimizing internal barrier coating processes for pulp molded food packaging. It enables researchers and process engineers to accurately simulate production spin-coating conditions on a small scale. Users can test various coating materials (PE, PLA, bio-polymers, PFAS-free solutions), determine optimal spin speeds, dosage, and viscosity parameters, and produce high-quality, coated samples for functional testing (leakage, grease resistance) before committing to full-scale production tooling.

3. Technical Parameters

4. Application

• Coating Recipe Development: Testing and optimizing new aqueous dispersions, bio-based coatings, or PFAS-free formulas.

• Process Parameter Validation: Determining critical parameters (speed, dose, viscosity) for new pulp substrate shapes.

• Small-Batch Prototype Production: Creating functional coated samples for client approval, shelf-life testing, or certification.

• Feasibility Studies: Evaluating coating performance on experimental or recycled pulp materials.

5. Customization

This R&D coater is designed for flexibility and can be customized to match your specific research needs:

• Chuck Size & Design: The vacuum chuck can be customized to fit unique or proprietary pulp mold shapes securely.

• Dispense System: The coating application system (needle type, multi-point dispensing) can be customized for specific material behaviors.

• Software & Control: Recipe programming and data logging parameters can be customized.

• Safety Enclosure: An optional transparent safety enclosure with extraction port can be added.

6. Key Features

• R&D Focused: Delivers production-like results on a lab scale, reducing development costs and time.

• Precision Control: Accurate control over spin speed (RPM), acceleration, and dwell time for reproducible results.

• User-Friendly: Intuitive touchscreen interface for saving and recalling coating recipes.

• Compact & Robust: Saves valuable lab space while being durable enough for daily use.

• Data Export: Enables recording and export of process parameters for analysis and reporting.

7. Support and Services

• Installation & Training: On-site or remote setup and comprehensive operational training.

• Technical Support: Dedicated phone and email support for troubleshooting and process consultation.

• Preventive Maintenance: Optional annual service contracts to ensure optimal performance.

• Spare Parts: Readily available inventory of key consumable parts (seals, tubing, etc.).

8. Packing and Shipping

• Packing: Securely packed in a heavy-duty foam-lined wooden crate for maximum protection.

• Shipping: Shipped via international air or sea freight. All necessary documentation (manual, certificate, invoice) is included. Lead time is typically 4-6 weeks after order confirmation.

9. FAQ

• Q1: What is the typical coating thickness uniformity achievable with this machine?

  • A: With proper parameter optimization, thickness uniformity of better than ±5% across a single sample can be achieved. Results depend on sample geometry, coating viscosity, and spin parameters.

• Q2: Can I use this machine to test both water-based and solvent-based coatings?

  • A: Yes, the standard materials are compatible. For solvent-based coatings, we strongly recommend the customized safety enclosure with extraction port for operator safety.

• Q3: How quickly can I change between different sample shapes?

  • A: Changeover is rapid. It primarily involves changing the vacuum chuck. We provide quick-release mechanisms, and additional customized chucks can be ordered for frequent sample types.

• Q4: Do you offer a trial or demonstration using our own pulp samples?

  • A: Yes, we offer a sample testing service. You can send us your pulp samples and target coating material, and we will run tests and provide a report on the processability and results.

• Q5: What is the minimum batch size this machine is suitable for?

  • A: It is perfectly suited for batches from a single sample up to several hundred pieces, making it ideal for R&D and pilot-scale production.
