The R&D department supports internal projects and external customers focusing on:

  • Renewable energy
  • Robot technique
  • Wafer tecnology
  • FEM analysis
  • Thermology
  • Acoustics
  • Flow analysis
  • Structure
  • Algorithm development

Tronrud’s R&D department has expertise within mathematical modelling and algorithm development. Advanced FEM (Finite Element Method) tools are utilized, in order to form a theoretical support for the more practical parts of the company's projects, as well as to solve pure R&D tasks for its customers.

The company’s experience is that building up an adequate theoretical foundation before getting too deep into a new project can be of vital importance, in order to solve a problem within the budget and the time frame, as well as to achieve an optimal technical solution.


The process of developing a machine, often starts with an idea before it ends on the drawing board. Tronrud Engineering is putting the ideas into practice.

All design is carried out using state-of-the-art CAD-systems. Tronrud Engineering has worked with 3D-CAD since the early 1990s and today the company uses Siemens PLM Software (NX and Teamcenter). The company also uses CAD to design electrical systems when these are a part of its projects.



An optimal combination of CNC controlled machinery and highly skilled personnel are the key strength of this department. The machinery equipment is on the cutting edge of today’s technology. Directly transfer from CAD to CAM ensures a high quality and short lead time of complex geometry.

The welding department uses common welding techniques like TIG, MIG and MAG, with certified welders. This department also has a workshop for sheet metal production.

The assembly department, with its highly skilled workers, ensures that the building and testing of machines are at a world-class level.


Water jet cutting is a trimming method for plate materials where one cut with water under extremely high pressure mixed with an abrasive material. With a water jet it is possible to cut most materials. Cutting carried out by a water jet makes very fine surfaces and requires little after treatment.
