Engel supports composites upcycling research at TH Rosenheim

 The Engel Group (Schwertberg, Austria), a European injection molding technologies manufacturer, has provided the Rosenheim University of Applied Sciences (TH Rosenheim, Germany) with a state-of-the-art injection molding cell. This system, comprising an Engel insert 500V/130 vertical injection molding machine, an Engel infrared oven and an Engel easix KR-10 articulated arm robot, is being used in the university’s teaching and research involving the processing of thermoplastic, recyclable composites, as well as the application of natural fibers.

A key research focus at TH Rosenheim is on composite materials. Its project, “Wood-based Bioeconomy,” deals with the production and processing of new materials from cellulose fibers and polypropylene (PP). The materials developed have properties similar to organosheets and can be processed accordingly. Particularly noteworthy is the upcycling approach of the project “ZIM - ReProHybrid,” in which materials from decommissioned car bumpers are shredded and processed into new organosheets that can be back-injected via injection molding with other — also recycled — materials from bumpers.

“TH Rosenheim plays a significant role in R&D, especially in the development of sustainable injection molding solutions and new materials,” says Dr.-Ing. Johannes Kilian, head of process and application technology at the Engel Group. “The collaboration is of great importance to us, as the university is not only known for its research strength in the field of plastics processing but also for its practice-oriented education. Our injection molding cell allows for the integration of innovative technologies and digital solutions directly into teaching, as well as testing a wide range of applications for their recyclability.”

TH Rosenheim is actively engaged in research on sustainable materials, particularly in the area of natural fibers as reinforcement for thermoplastics. According to Prof. Dr.-Ing. Norbert Müller, dean of studies for the degree programs in plastics engineering and sustainable polymer technology, Engel’s technology will enable them to “conduct practical investigations and further explore the use of sustainable materials in technical applications and in construction. Construction is significant for TH Rosenheim, as it recently acquired the right to award doctorates in ‘Advanced Building Technologies.”  Müller says this is a crucial sector where further R&D are needed for the recycling of materials, and where recyclable material systems based on natural fiber-reinforced plastics offer great potential for innovation. 

Digitalization also plays a central role in TH Rosenheim’s research. Through the use of Engel’s iQ process observer, for example, the university is able to gather data that, through semantic processing, enables insights applicable to other uses. This represents a significant step toward machine learning and AI-supported applications in plastics processing.

“Digital process monitoring opens up new possibilities for making production processes more efficient and sustainable,” explains Müller. TH Rosenheim will continue to expand this area, as they believe the combination of digital technologies with practical projects offers high potential.

In addition to supporting teaching and third-party funded research, the Engel production cell is also used for direct R&D collaborations. Companies and institutions collaborating with TH Rosenheim can test technologies and trial new applications using this equipment.
