From materials to polymer applications

The iRAP institute addresses scientific and technical challenges in the field of plastics processing. With advanced expertise in materials, application development and product lifecycle assessment, iRAP is able to deliver efficient solutions to specific industry demands.

Research focus areas

The iRAP institute has advanced expertise in four strategic research areas.

  • Design and development of injected plastic and ceramic products and their molds
  • Rheological and mechanical simulation
  • Prototyping on injection machines
  • CIM sintering and debinding
  • Injection of polymer bonded magnets
  • Development of high value compounds
  • Piloting and scaling up of extrusion and compounding processes
  • Characterization and testing of materials in the laboratory
  • Cradle-2-Cradle concepts and implementation
  • Surface functionalization with atmospheric plasma
  • Coatings
  • Nanomechanical analysis
  • Surface texturing and tribology in the field of plastics processing
  • Design and development of products for lightweight structures
  • Industrialization and recycling of composites based on continuous fibers
  • Mechanical simulation
  • Prototyping

iRAP provides a range of R&D services in the field of plastics processing.


Industry partners who choose to work with iRAP can benefit from project co-funding by the Swiss Confederation (through Innosuisse, the Swiss Innovation Agency), the Cantons (as part of its New Regional Policy, “NPR”), and the European Union R&D Framework Program. iRAP also offers collaboration in the form of services (mandate).

Depending on the nature of the project, iRAP has the capacity to combined knowledge and expertise from the other HEIA-FR institutes and competence centers. In particular with PICC (bioplastics and circular economy), ChemTech (polymer chemistry), iPrint (digital printing) or iCoSys (data analytics). That enables iRAP to offer complete and pragmatic industrial solutions.


The iRAP institute relies on state-of-the-art equipment to carry out its advanced research and development.
