Injection moulding compounding

New processing approaches such as direct inline-compounding can be used to process highly-filled and/or long fiber-reinforced thermoplastics in the injection-moulding process. This technology allows the production of complex structures to be coupled with a high degree of automatisation in a one-step process. Injection-moulding compounders (IMC) are characterized by the inclusion of a twin-screw extruder with a high plasticizing performance into the injection concept. The injection-moulding compounder allows feeding of endless fiber-rovings into the melt near the end of the twin-screw extruder. This approach leads to longer fibers in the final part, allowing for better mechanical properties compared to the commercial long fiber compounds available in the market in form of granulates. In addition, “Hybrid Materials”, containing long fiber composites in combination with other micro/nano fillers can be manufactured, targeting special applications. Tailoring the process using chemical blowing agents allows foaming of such complex compounds in order to further open up newer applications fields such as lightweight materials, isolation, and etc.
