Film Coating Tunnel Oven
Category：Tunnel Oven Production Line
Introduction
The Film Coating Tunnel Oven is an industrial-grade continuous heat treatment equipment specially designed for drying and curing coated films.It adopts a tunnel-type structure combined with a conveyor transmission system, allowing coated films to continuously pass through multiple heating zones. Through precise control of temperature and airflow speed, the equipment can rapidly cure, dry, or dehydrate surface coatings on films, making it a key processing system in film manufacturing and post-processing industries.
Applications
1. Film Coating Curing
Used for thermal drying and curing of surface coatings on:
Optical films
Photosensitive films
Other functional coated films
2. Polymer Film Drying
Widely used for curing inks and functional coatings on film substrates such as:
PET films
PI films
PVC films
3. Composite Material Heat Treatment
Suitable for:
Heat pressing and forming of multi-layer film composites
Adhesive curing after lamination processes
4. Electronic Insulation Material Baking
Applied for continuous dehydration and drying of coatings on flexible circuit board substrates and electronic insulation materials.
