Research and activity

Manufacturing is increasingly important for further development and to ensure further welfare of the Norwegian society. The crisis in the oil and gas industry is a contributing factor for this. The trend of moving production to low-cost countries is about to turn. Technological development with more available automation with lower investment and more flexible solutions is one of the reasons for this.

Production is becoming increasingly complex with, among other things, sustainability, digitization, hybrid structures and multi-materials as well as new materials and processes, such as bio-materials and additive production. Norway as a production country has good prospects with research-based innovation, high level of knowledge and access to sustainable energy.

Hovedprosjekt MultiMat stipendiat 

The industrial partners in MultiMat are manufacturing products based on combinations of plastic materials, composites and metals with a high degree of precision and strict requirements for a global market of demanding customers. Continuous innovation in both products and processes is needed to stay competitive, and the right choice of materials is a key factor. Product solutions are increasingly combinations of different materials where each material's best properties are utilized to achieve high performance combined with low weight and cost. The implications include challenges in joining and assembly processes, both in quality and efficiency.

The overall idea in the project is to develop new products and production processes based on a combination of different materials, with integrated and automated injection moulding, joining and assembly. The project will enable the realization of new and innovative products with new material combinations that cannot be realized in today's processes. The project will also achieve increased manufacturing productivity and effectiveness by developing automated, integrated and flexible technological solutions. These solutions will reduce the number of process steps, and secure the required quality, the cost-effectiveness and the quick response to changing customer demands.

The additive manufacturing (AM) market (machines, materials, manufacturing services) has grown considerably for many years. A large number of AM processes and materials are available, and new or improved processes and materials are introduced every year.

However, there are still several challenges for AM technologies as industrial manufacturing processes. In terms of part performance, the main challenges are material properties (including their anisotropy caused by the layerwise fabrication), surface finish, and part-to-part consistency (properties, dimensions). In some cases, the (effective) material properties of AM parts can be quite different from those known for traditional manufacturing processes.

The need for better knowledge of material properties and their consistency is widely recognized within the AM industry. The overall objective of the MKRAM project is to build knowledge on the effective mechanical properties resulting from AM processes. The MKRAM project focuses on two selected AM processes, powder bed fusion for metals and polymers. Furthermore the focus is on the following material groups: Nickel alloys, maraging steels and polyamides.

Lean Management

A growing number of companies have global ownership, and are included in global value chains and networks across the world. It is no longer sufficient to look at these questions only within a national framework. In Lean Management, we will lift the theme beyond the national level, and study the practice of lean in a broader context. The themes will be the kind of leadership that is required to be competitive within lean, the manner in which businesses working across value chains, and how lean is practiced in other Nordic countries.

The additive manufacturing (AM) market increases rapidly, and AM enters new industrial sectors. The overall idea of the project is to use rather inexpensive mould inserts made by AM (mostly non-metal AM) for injection moulding of plastic parts with properties similar to those of parts moulded with conventional steel moulds.

The objective is to develop methods for the manufacturing and use of inexpensive AM mould inserts for injection moulding, so that the industry can reduce costs and time in the product development phase, and also use such mould inserts in the regular production of small series.

The project is based on recent developments in improved AM materials and AM processes. In the project we have tested various AM technologies and mould/insert constructions, for real parts to be injection moulded, and we have also performed studies in order to gain fundamental knowledge about the performance and possibilities of such mould inserts in injection moulding processes. We have completed several case studies with demanding injection moulded components from the participating companies

Intelligent Bolted Joints

Bolt connections are commonly used structural fasteners in many type of industries including mechanical, aerospace and civil engineering. Bolts are fastened to maintain specific preloads during service to ensure the safety and reliability of structures. However, in many structures (e.g., wind turbines, oil & gas installations), maintaining the primary preload might be difficult due to external impacts (such as wind force) resulting in high vibrations followed by reduced tension which loosens the bolt connections. Periodic maintenance of the multipoint bolts is thus crucial for proper operations and avoidances of structural failure. However, measuring the condition of every single in-service bolt is often very costly and almost impossible in most applications due to the large number of bolts involved. Developing an effective (technological and economical) bolted joint monitoring system is thus an important engineering significance.

In this project, we aim to develop wireless enabled intelligent bolted joints for automatic monitoring. The monitoring can be used for preventing accidents (warning if a bolt is broken or loosened) and improved maintenance cycles where re-loading only the bolted joint that needs it. The novel aspect of this project is to present and develop the paradigm of self-powering, radio integrated, load-sensing intelligent bolted joints for large scale monitoring of critical structures. This is an important research topic as current methods are highly time-consuming and expensive involving regular manual operations for checking and maintaining the bolt preloads.

Additive manufacturing (AM) technologies are gaining increased attention from both scientific and industrial sectors, since it offers high degree of freedom that can theoretically produce parts having any possible geometry with extremely complex shapes layer-by-laser. The two most widely used AM processes are the selective laser melting (SLM) and electron beam melting (EBM), both belonging to the powder bed fusion category. Biomaterials (such as pure-Ti and Ti6Al4V) has been extensively processed by both SLM and EBM technologies. These materials have high specific strength, low modulus, good fatigue strength and good osteoconductivity. Even though these materials are considered to have low modulus, it is still much higher than the modulus of the human bone. Hence, these materials can be fabricated in the form of structures instead of the bulk form to reduce their modulus and to match with that of the human bone. These AM processes are good candidates for manufacturing structures and hence are extensively used in the field of bio-based industries in the form of scaffolds. The biggest advantage of fabricating biomaterials using the SLM/EBM process is that both microstructure and surface roughness can be varied to a reasonable extent, which is expected to affect both mechanical properties and cell growth characteristics. Moreover, the research on cell growth studies, especially osteoconductivity and achieving maximum osteopromotivity of such samples are still at their primitive stage and evoke opportunities to pioneering the research in this field. Therefore, the research in this field is necessary for knowledge creation, dissemination and innovation at both scientific and industry levels. The estimated business potential of bone grafting industry is around $850 million and it is rapidly increasing because of technological advancements in the area of 3D printing, which will boost several industrial opportunities in the Innlandet area.
