Sprue Recycling Conserves Resources

Thermoset Molding compounds crosslink irreversibly during processing. Both the material from the sprue runner system, the process start-up and scrap components are typically sent for thermal recycling as waste. The granulation and direct recycling of this material in the injection molding process increases resource efficiency due to material recycling, but has an influence on the mechanical properties of the components. In the present study, the necessary parameters are investigated.
