Roll-to-Roll Continuous Doctor Blade Coating Line – Flexible Electronics & Optical Film Mass Production
Product Overview
Our doctor blade coating line enables continuous or batch coating of slurries, pastes, inks, and sol-gel materials onto glass, metal foil, polymer film, or paper. It features high thickness uniformity (< ±2%), low material waste, and stable gap control. Ideal for R&D labs, pilot lines, and full-scale production.
Customizable options include: coating head type (doctor blade / slot die / comma), wet thickness range, drying zone length, substrate handling (sheet-fed or roll-to-roll), and environmental enclosure (dust-free / humidity control / inert atmosphere).

Frequently Asked Questions
Q1: Can this line handle both rigid glass and flexible PET film?
Yes. We offer customizable substrate fixtures: vacuum chuck for glass, pin-lift for rigid panels, or roller nip for film.
Q2: What is the minimum coating quantity for a lab-scale line?
With a small slot die, you can coat with just 5-10 ml of slurry. Die reservoir volume is customizable down to 2 ml.
Q3: Is the drying oven configurable for inert gas (N₂) environment?
Absolutely. Oven gas purging and oxygen monitoring are customizable options for moisture/air-sensitive materials.
