CoreTech system receives U.S. patent for three-parameter fiber orientation model

CoreTech System Co., Ltd. (Moldex3D), a provider of 3D CAE simulation for the injection molding industry, was granted a patent from the U.S. Patent and Trademark Office for the company's technology that reportedly brings high-accuracy prediction to the orientation distribution of injection molded fiber-reinforced thermoplastics and can be applied to a wide range of injection molding needs.

This new patent describes a new fiber orientation model, anisotropic rotary diffusion model combined with retarding principal rate (iARD-RPR), that can accurately detect and describe the changes well in fiber orientation, both short and long fibers included. The company says the fiber model provides significant enhancements to previous models and enables superior prediction accuracy to largely eliminate shrinkage and warpage problems induced by the effect of anisotropy of fiber orientation....
