Two types are lined up: SW-CFRP rolls and SW-GFRP rolls.
Our unique pipe manufacturing technology, known as the SW (Sheet Winding) method (a molding technique that layers prepreg sheets and heats and cures them), produces composite materials with various characteristics as mentioned above. - SW-CFRP rolls are made of carbon fiber, making them lightweight, low inertia, and suitable for ultra-high-speed rotation. With a high longitudinal elastic modulus, they exhibit minimal deflection and can achieve greater rigidity than metal rolls, allowing for smaller diameter rolls and contributing to space-saving designs. - SW-GFRP rolls are made of fiberglass and are suitable for rolls that require relatively low rigidity or for insulation applications that leverage the properties of FRP. Additionally, they can be manufactured at a lower cost, allowing us to propose rolls tailored to your needs by effectively combining them with CFRP. 【Features】 [SW-CFRP Rolls] ○ Lightweight and low inertia, suitable for ultra-high-speed rotation ○ High longitudinal elastic modulus results in minimal deflection and increased rigidity compared to metal rolls ○ Enables smaller diameter rolls, contributing to space-saving designs ● For more details, please contact us or download the catalog.

basic information
【Lineup】 [SW-GFRP Roll] ○ Lightweight → Weight is about 1/4.5 that of metal → Reduces the workload during maintenance and replacement, enhancing the safety of workers → Improves the durability of related components such as bearings and motors ○ Low Inertia → Significantly reduces the moment of inertia, improving the responsiveness to transported items and the precision of rotational motion control, thereby enhancing product quality and yield → Achieves cost reduction through reduced driving energy ○ Self-weight Deflection → Self-weight deflection is equivalent to that of metal rolls due to lightweight design ○ Thermal Properties → Coefficient of linear expansion is 65-70% of that of metal, maintaining relatively high dimensional stability even in hot air environments around 100°C ○ Chemical Properties → Weak against strong acids and moderate to strong alkalis, but resistant to alcohols, acidic salts, sulfur dioxide gas, acetic acid, phosphoric acid, sulfuric acid, etc., and does not corrode like metal ○ Electrical Properties → High electrical insulation, with no issues even in AC 20KV - 5 minute tests ● For more details, please contact us or download the catalog.
