Uniform Heating

Our unique heaters were developed exclusively for this equipment. The structure of its furnace can stabilize far-infrared heaters as well as atmosphere temperature, which enable precise temperature profiles.

Measures for curls and wrinkles during conveyance

Equipment design solves the problems such as curls and rinks of products caused by heat.

Maintenance improvement for heating space

The top of the furnace opens widely for easy feeding of film prior to operation and periodical maintenance.
