Technical centre­ Additive­ manufacturing

The technical centre for additive manufacturing offers access to the latest 3D printing technology and innovative manufacturing processes. With a large number of established 3D printers, including FFF, SLS and the Arburg Freeformer, we cover a wide range of additive manufacturing processes.

The focus is on the technologies and processes we have developed in-house, in particular our hybrid production systems, which enable the processing of standard granulate and the production of large-volume moulded parts and prototypes. We are not only involved in system development, but also in the development of materials as well as slicing and production strategies that lead to solutions such as non-planar path planning or screw extrusion-based additive manufacturing.

This is complemented by state-of-the-art peripherals and sensors, such as thermal imaging cameras, to monitor and improve the quality and precision of each printing process. This unique infrastructure creates a variety of methods for public and joint research and development projects!

Technical centre for extrusion

In the technical centre for extrusion, we offer comprehensive solutions for the analysis and optimisation of modern processes. This includes process and processing analyses for new materials, recyclates and the production of prototypes and samples. Various mould technologies and mixing elements can be tested under practical conditions. We cover extrusion processes such as flat film, blown film and profile extrusion as well as foam extrusion. We also offer forming processes such as extrusion blow moulding, stretch blow moulding and thermoforming.

Injection moulding technology centre in the Plastics­ Innovation­ Center 4.0

The state-of-the-art injection moulding technology centre in the Plastics Innovation Center (PIC 4.0) at IKV offers excellent facilities for public and bilateral research and development. With 10 injection moulding machines with a clamping force of 30 to 240 tonnes, a wide range of applications is available. The additional 60 injection moulding tools available allow the production of simple and standardised test specimens through to application-oriented demonstrators.

In addition to the injection moulding machines, state-of-the-art technology is also available, including dryers, hot runner systems and temperature control units. The digitalised systems and customised production cells enable maximum precision and efficiency, which are supplemented by various control systems. In addition, various processes such as injection compression moulding, thermoplastic foam injection moulding, metal-plastic composite technologies and optics offer a wide range of possible applications.

This broad spectrum of technologies and equipment makes our technical centre an ideal partner for public and bilateral research and development projects.

Technical centre ­Compounding ­& Recycling

In our technical centre for compounding and recycling, we offer a wide range of options for the production of individual compounds and the regranulation of flakes and post-consumer materials. Depending on the material and requirements for the desired pellets, we use twin-screw or planetary roller extruders and various dosing technologies. We use processing and process analyses to optimise materials and remove volatile components, such as odour-forming components, by means of degassing and innovative drying technologies. The finished cold cut compounds or regranulates can then be further processed into samples or test specimens in the extrusion technology centre or PIC 4.0 or examined in detail in the centre for plastics analysis and testing.

Technical centre ­ rubber ­technology

In the technical centre for rubber processing, we offer a wide range of options for producing customised rubber compounds and optimising various mixing phases in the rubber internal mixer. By recording compound-dependent fingerprints, such as temperature, torque and power, we optimise the mixing time and filler addition. The compounds produced can then be further processed in a heating press or in the technical centre for extrusion and rubber processing. In addition, analyses and measurements such as viscosity, Shore hardness or surface topography provide detailed insights, for example into filler distribution in the material, and thus contribute to quality assurance.

In addition to thermoplastic-based processes, a particular focus is on rubber processing using extrusion and injection moulding. Here, for example, vulcanisation processes, tool developments and the production of foamed elastomer components are developed and optimised.

Technical centre for fibre-reinforced plastics

The fibre-reinforced plastic pilot plant (FRP pilot plant) at IKV is a state-of-the-art research area for innovative lightweight construction concepts. With industry-relevant plant technology, it enables the processing and analysis of a wide range of FRP technologies, including the resin injection process (RTM), pultrusion, autoclave and pressing processes, prepreg processing and automated fibre laying processes. New material combinations, production processes and simulation techniques are developed in close cooperation with industrial partners. The focus is on sustainable materials, automated production and the functionalisation of components. Students and scientists have the opportunity to research current issues in FRP technology under realistic conditions. The technical centre thus makes a significant contribution to the further development of sustainable and efficient lightweight structures.

Technical centre for polyurethanes

In the field of polyurethane technology, the technical centre offers an excellently equipped research environment for the development of innovative polyurethane applications. With industrial processing machines – including high- and low-pressure dosing systems (2K and 3K) and mould carriers with clamping forces of 20 to 400 t – it enables the practical production and analysis of a wide range of components. The focus is on determining process-related material data and inline quality assurance. The technical centre also supports industrial partners in the optimisation of processes and materials and offers students practical training. Through close co-operation with industry and interdisciplinary research, it creates optimal conditions for application-oriented innovations and the further development of polyurethane technology.

Plasma and surface technology technical centre

Plasma and surface technology at IKV focuses on low-pressure processes, as they offer many advantages for coating plastics compared to atmospheric pressure processes. The technical centre houses coating systems for flat products, hollow bodies, tubular bodies and web material. These systems have been designed, constructed and set up at IKV, which gives us a high level of expertise in system technology and control.

Changing the surface properties of plastic products is always a development process, as the product itself influences the layer deposition. In order to be able to carry out this development quickly and validly, the systems have suitable sensor technology with which the processes can be monitored and controlled. In conjunction with the analysis options in the Centre for Plastics Analysis and Testing, the coating properties and the functionalities achieved can also be tested.

The equipment at the Plasma and Surface Technology Centre therefore provides all the necessary degrees of freedom to equip any plastic products with new surface functionalities: gas and migration barriers, hydrophilicity and hydrophobicity as well as scratch resistance are currently the most common requirements that we develop in research projects or with industrial customers.

Test laboratories

The Centre for Plastics Analysis and Testing (KAP) is equipped with comprehensive and modern facilities for testing the mechanical, physical, chemical and morphological properties of plastics. Thanks to many years of expertise in materials and processing technology, solutions for challenges in plastics technology are provided quickly and efficiently.

An interdisciplinary team of physicists, chemists, engineers, technicians and materials testers makes it possible to work on a wide range of problems in both breadth and depth.
