Why Advanced Hot Runner Simulation?

Hot runner solutions have been utilized in various plastic injection molded products, such as bumpers, automotive instrument panels and LCD/TV panels. Hot runner molds bring advantages including material and energy cost savings and shorter cycle times, for the runners that are eliminated in the process. However, the applications of hot runner systems are comparatively more complex and commonly face the challenge of elaborate temperature control and the risk of thermal degradation of plastic materials. Moldex3D AHR provides simulation tools for designers and engineers to obtain mechanism and critical information in hot runner molding. Users are able to investigate the processes and detect potential defects, and further achieve design optimization. Moldex3D helps companies to develop products with high quality and low costs and win in a globally competitive market.
