Industrial Wide-Format Roll Coater for Metal & Panel Coating
This customizable roll coater is a continuous coating system designed for uniform application of liquid adhesives, paints, functional coatings, and hot melts onto flat or flexible substrates. Available in industrial wide-format, laboratory R&D, and hot melt configurations. The system is fully customizable in roller configuration (2-roll / 3-roll / reverse roll), coating width, drying modules, and automation level. Ideal for metal coil coating, packaging films, textiles, foam lamination, engineered panels, and functional material production. Roller gaps, speed ratios, and nip pressures are precisely controlled to achieve coating thickness from 1 µm to several hundred microns with exceptional uniformity.

Frequently Asked Questions
Q1: What is the difference between a 2-roll and a 3-roll coater?
A: A 2-roll coater transfers coating directly from the applicator roll to the substrate, suitable for thicker coatings. A 3-roll coater adds a metering roll for precise coating thickness control and is better for thin, uniform layers. The configuration is customizable based on your application.
