Contributing to One-Shot Molding and Improved Production Efficiency: Nittobo’s Commingled Glass Cloth
Combining the toughness of glass fiber and the moldability of resin in a single sheet. Nittobo’s "Commingled Cloth" enables one-shot molding of complex shapes and dramatic productivity improvements.
Nittobo’s "Commingled Glass Cloth" is an innovative composite material created by twisting and weaving high-strength "glass fibers" with thermoplastic "organic fibers (plastic fibers)" using proprietary technology. Its greatest feature lies in "one-shot molding," which allows products to be manufactured using only heat and pressure. Since the resin is already uniformly mixed with the fibers, the material exhibits exceptional mold-following capability and impregnation. This allows for the precise molding of deep-drawn shapes and complex contours—previously difficult to achieve—in a single process. Consequently, it strongly supports a dramatic shortening of manufacturing steps, cost reduction, and labor savings. Furthermore, by leveraging the properties of thermoplastic resin, post-molding reprocessing and recycling are made easy, contributing to a reduced environmental footprint. While lightweight, it possesses high reaction force and superior impact resistance that surpass aluminum, providing a new standard for manufacturing sites where both strength and productivity are required.
