This report covers a product development project conducted as Bachelor of Science thesis forthe Innovation & design engineer program at Karlstad University.The assignment was supplied by MMB Consulting, Kristinehamn. The purpose of this projectwas to find an alternative way of shaping wire-net insulation mats. This insulation product isused for fire and thermal insulation of technical installations. The insulation consists of stoneor glass wool with a sewn on steel wire netting on the out facing side. This netting has thepurpose to enable fastening to e.g. ventilation ducts and to provide bounding of joints. Thiswire netting makes regular methods for fitting stone or glass wool non applicable. Theexisting method for shaping wire-net insulation has flaws due to not being designed for thisapplication. These flaws include poor ergonomics, efficiency and low result quality.The objectives with this project is to find a new method that makes fitting of wire-netinsulation more efficient and safer for the user regarding personal safety and ergonomics.The work has been conducted according to the methods of the industrial product developmentprocess and the design methodology.The project resulted in a motor driven tool for shaping wire-net insulation that according to atheoretical foundation has proven to be more user adapted through being designed for goodergonomics and by offering a simpler handling. This solution is also considered to be moreefficient and to give better results than the present solution. Some correlation betweenreductions in energy losses from technical installations and the new method is detectable.
