With the DuroSet process, KraussMaffei helps you to produce high-quality, dimensionally stable components from free-flowing molding compounds. Injection molding machines are used that have a plasticizing system with mechanical back-twist lock. This ensures constant shot weights and high reproducibility.
In contrast to thermoplastics, thermosets cannot be re-melted. Thermosets react irreversibly when heat is applied in a hot mold. Adapted machines and processes are required to process these reactive molding compounds. Even the condition of the raw materials differs significantly from the granulates commonly used for thermoplastics.
The processing parameters also differ greatly from the usual values for thermoplastics. For example, the tools are usually electrically heated to 150 - 200 °C, while the plasticized parts are tempered or cooled with water or heat transfer oil.
