Product Description
High-Precision Intermittent Scraper Coating Line for Lithium-Ion Battery – Customizable Scraping Zone Accuracy & Multi-Zone Drying
This customizable knife coating production line is a continuous or intermittent coating system that uses a precisely controlled doctor blade to apply uniform layers of liquid coatings onto flexible or rigid substrates. Available in roll-to-roll continuous production, laboratory R&D, and high-precision intermittent configurations.
The system is fully customizable in coating width, drying length, coating method (comma blade / doctor blade / rod coating), and automation level. The coating thickness is controlled by the precise gap between the blade and the substrate or backing roll, enabling wet film thicknesses from 5 µm to several hundred microns with exceptional uniformity (up to ±1-2 µm accuracy).
Working principle: The coating material is supplied to the substrate surface, and the doctor blade (comma blade or scraper) meters the excess coating to leave a precisely controlled wet film thickness. The coated substrate then passes through drying ovens where solvents are evaporated or resins are cured. This method is widely used in lithium-ion battery electrode manufacturing, adhesive tape production, and functional film coating.

Frequently Asked Questions
Q1: What is the difference between a comma coater and a doctor blade coater?
A: A comma coater uses a reverse-rotating comma-shaped blade against a backing roll, providing more precise and uniform coating for medium-to-high viscosity materials. A doctor blade coater uses a stationary blade directly against the substrate or roll, simpler in design and suitable for lower viscosity coatings. Both methods are customizable based on your material viscosity and accuracy requirements.
