Introduction

This laboratory roll-to-roll coating machine is designed for continuous coating trials, material evaluation, and coating process development. Compared with the oven-free version, this model incorporates a 1 m drying oven, allowing users to test coating materials that require thermal drying after application.

The machine can be configured with a doctor blade coating head, a micro-gravure coating head, or both, depending on the coating material and process requirements. This flexible configuration makes it suitable for evaluating different coating methods and drying conditions on continuous web substrates.

Key Features

- Integrated 1 m Drying Oven: Supports coating trials involving adhesives and other materials that require thermal drying.

- Flexible Coating Head Configuration: Choose doctor blade coating, micro-gravure coating, or a combination of both according to process requirements.

- Roll-to-Roll Web Handling:Supports continuous coating trials on flexible web substrates.

- Customizable Process Configuration Coating head selection and machine configuration can be tailored to the material properties and intended application.

Product Details

1 m Drying Oven

The integrated 1 m drying oven provides a heated drying section after coating, making the machine suitable for trials involving adhesives and other formulations that require thermal drying. Drying temperature and process conditions should be selected according to the material properties and the required coating performance.

Flexible Coating Head Options

The machine can be configured with a doctor blade coating head for flexible coating-gap adjustment, a micro-gravure coating head for applications suited to gravure-based metering, or both coating heads to support comparative process trials. The final configuration depends on the required coating thickness, material viscosity, substrate, and coating method.

Roll-to-Roll Coating System

The roll-to-roll design enables continuous web transport through the coating section and drying oven. It supports repeatable laboratory trials and helps users evaluate coating performance under controlled process conditions.

Application-Oriented Configuration

The coating head arrangement, drying conditions, and other machine details can be selected according to the customer's formulation, substrate, and experimental objectives. This allows the equipment to be configured for different coating development tasks.

Applications

This laboratory coating machine is suitable for research and development involving:

- Adhesive coating trials

- Water-based and solvent-based coating formulations, subject to material compatibility and drying requirements

- Coating process development and optimization

- Comparative evaluation of doctor blade and micro-gravure coating

- Continuous coating tests on flexible web substrates

Customization

The coating head configuration and relevant process parameters can be customized according to the coating material, substrate, target coating thickness, and drying requirements.

For a suitable configuration, please provide details of your coating material, viscosity, substrate type, target coating thickness, operating speed, and required drying conditions.
