Energy efficiency and sustainability through lightweight construction
A consortium of industry and research partners along the entire value chain of duromer plastics, including the Fraunhofer Institute for Chemical Technology ICT and the Karlsruhe Institute of Technology (KIT), has launched the project “Lite2Duro - Lightweight construction through resource- and CO2-efficient balanced injection molding of duromer molding compounds”.4 Oct 2021
They are researching ways to increase sustainability and energy efficiency in the processing of duromer plastics. They are also investigating three important process-related obstacles, further developing simulation methods and demonstrating solutions in industrial applications.
The first step is developing an active cavity balancing system that enables process-reliable, economical and resource-saving production of multiple, identical precision components from duromer molding compounds at the same time. The second step is to development an injection molding machine capable of increasing the processable plastic volume per cycle, which results in more economical and energy-efficient large-scale production overall. The third step is to create a recycling strategy for the sprue manifold that is based on granulating the hardened plastic and returning it directly to the injection molding process as a reinforcing material.
