With excellent chemical resistance, it protects rolls and products from harsh environments.
【Product Features】 Excellent chemical resistance for stable operation in harsh environments The entire roll is made of polyvinyl chloride (PVC), providing high resistance to chemical substances, including inorganic acids. This prevents corrosion and degradation, ensuring stable operation of production lines in harsh environments. Coating processing for existing metal rolls is also available It is possible to coat the metal rolls currently in use by customers with polyvinyl chloride (PVC). This allows for easy enhancement of chemical resistance and durability while utilizing existing equipment. Optimal surface precision polishing tailored to applications Depending on the products handled by customers and the conditions of the production line, precision polishing of the surface can also be performed. Leveraging years of expertise, we propose the optimal specifications to solve customers' challenges.

Company information
We are Osaka Senshoku Kikai Co., Ltd., the pioneer and first manufacturer to domestically produce "Expander Rolls" in Japan. We provide fundamental solutions to eliminate "wrinkles," "shrinkage," and "slippage" in Roll-to-Roll web handling processes for films, metal foils, and non-woven fabrics. [Our Core Strengths] ◆ Japan's Only "Precision Curved Grinding" Our unique technology enables precision grinding while the roll is in its curved state. This eliminates vibration even on high-speed lines for ultra-thin films, dramatically improving your production yield. ◆ Ultra-Low Torque "Drive-less Design" No motor required. Our rolls rotate smoothly driven solely by the web's conveying force, effectively preventing slip scratches on your products. ◆ "Special Materials" & "Retrofitting" Fully compatible with special materials such as "fluorine rubber" (FKM), which is essential for high-temperature and adhesive lines. We also have an extensive track record of replacing/retrofitting other manufacturers' flat-type rolls with our curved rolls. ◆ Repair & Refurbishment for All Brands We provide repair and restoration services for expander rolls from any manufacturer, both domestic and international. [Proven Track Record] Since our founding in 1951, our cutting-edge technology has been featured on major national TV news programs and exhibited at the Expo 2025 Osaka, Kansai. Beyond standard catalog specifications, we promise to offer the optimal proposals and solve your line's most difficult challenges. Please feel free to contact us.
