Frequently Asked Questions
What is the typical production capacity of this inline spray coating line?
Production capacity depends on product size, conveyor speed, and number of spray stations. Typical capacity ranges from 500 to 5,000 pieces per hour. For example, a 600 mm wide line running at 8 m/min can coat approximately 2,000–3,000 small to medium-sized industrial trays per hour. Capacity is fully customizable by adjusting line length and speed.
Can this line coat both the inside and outside of molded fiber products?
This model is optimized for internal surface coating. For products requiring both internal and external coating, we recommend a two-pass configuration (internal coat, flip, external coat) or consider our double-sided spray line (Product 3).
How does the temperature and humidity controlled spray booth improve coating quality?
Water-based and bio-polymer coatings are highly sensitive to temperature and humidity. If the environment is too dry, the coating dries too quickly and may crack. If too humid, the coating may not cure properly. The controlled booth maintains optimal conditions (18–28°C, 45–65% RH), ensuring consistent film formation, adhesion, and barrier performance regardless of factory conditions.
What types of coatings can be used on industrial pulp packaging?
The line is compatible with water-based barrier coatings (acrylic, polyurethane), bio-polymer dispersions (PLA, PHA, PBAT), solvent-based coatings, and UV-curable coatings. For food-contact applications, we recommend PFAS-free, FDA-compliant formulations. For heavy-duty industrial applications requiring high abrasion resistance, polyurethane or epoxy coatings are recommended.
What is the typical VOC emission level of this system?
With water-based coatings, VOC emissions are typically below 50 mg/m³. The integrated paint mist capture system removes >98% of particulates, and emission concentrations are maintained below 15 mg/m³. For solvent-based coatings, we offer activated carbon filtration to meet local environmental regulations.
