There are various methods for molding composite materials, but generally, it is done through external pressure molding. The irregular cross-section tubes can be molded using our unique internal pressure molding method, allowing for the formation of CFRP tubes with various cross-sectional shapes, such as polygons, as shown in the photo. FRP can be considered the only material that allows for the design of variable thickness structures among structural materials. Therefore, it is necessary to integrate the structure as much as possible, avoid secondary bonding, and ensure a compact structural design. *For more details, please download the PDF or contact us.*

CFRP, due to its characteristics of being lightweight, high rigidity, and high vibration damping, is widely used in robotic arms exemplified by liquid crystal transport robot hands. In transport operations, high-precision position control and the damping time of vibrations during transport significantly affect productivity, making it an essential material as a component. ▼ Technology Introduction ◆ A lightweight, high-rigidity CFRP robot hand that reduces the amplitude halving time to "1/3" We have developed a structural component with high vibration damping properties without compromising the lightweight and high rigidity of the CFRP angular tube structure hand. *Comparison results with our existing structural components are included in the downloadable materials.
