This product is an assembled unit consisting of four parts, all molded from the same composite resin formulation. It is commercially available under the name “CARBLACK Adjustable Wrench.”

At Shinshu Yoshino Electric, we have developed a proprietary composite molding technology known as the Direct Fiber Feeding Injection Molding Method. By modifying the injection molding machine, continuous fibers are fed directly into the process, enabling the production of high-performance CFRTP components.
