Steel Belt Film Baking Tunnel Oven is a high-precision, continuous industrial heat treatment and drying system. It uses a high-strength stainless steel belt as the conveying carrier and is specially designed for continuous heating, drying, curing, and baking of cast film, coated films, and various thin-film materials.

Core Applications

New Energy Battery Industry

Used for the continuous drying and curing of lithium battery separators and electrode coating films.

Polymer Materials Industry

Used for the casting process and high-temperature baking of PI (polyimide) films, PET films, and optical films.

Electronics and Semiconductor Industry

Used for drying coated films on flexible printed circuit board (FPC) substrates and electronic paste films.

Chemical and Advanced Materials Industry

Used for solvent removal and thermal curing of various functional coatings and composite film materials.

Equipment Features

1. Extremely High Flatness

The stainless steel belt surface is as smooth as a mirror, preventing wrinkles, local deformation, or pinholes during thermal expansion and heating of the film material.

2. Highly Precise Temperature Control

The system usually adopts multi-zone independent microcomputer temperature control. The temperature accuracy can reach ±1°C or even higher precision.

3. High-Efficiency Continuous Production

With a long and narrow tunnel structure, the equipment supports fully automatic loading and unloading, enabling 24-hour continuous mass production on automated production lines.

4. High Cleanliness

The stainless steel belt itself does not generate particles or residue and is easy to clean, meeting the production requirements of Class 10.000 or Class 1.000 cleanrooms.

5. Energy Saving and Environmental Protection

The system integrates advanced hot air micro-circulation or infrared radiation heating technology and is equipped with efficient exhaust systems and heat recovery devices to reduce energy consumption and improve environmental performance.
