PAPER

OSAKA FUJI Corporation also has superior technological capabilities and a proven track record in the paper manufacturing industry in the field of facility repair and refurbishment. We provide overlay welding services for equipment used in the front-end process, which handles the raw materials, and thermal spraying services for equipment used in the back-end process, which is referred to as the papermaking process. Some of the services we offer are introduced below.

Example applications of welding technology

Rotary kiln tire

Processing of an Kiln facility in a paper factory

Rotary kiln tire

Processing of the screw that transports ash after incineration
