Teknikassistans have the skills required to apply anti-corrosive treatment, sealing, adhesive and dampening material in a correct and efficient manner, regardless of type of vehicle. Based on a thorough analysis, we develop a suggestion for a suitable application process. There are a number of factors that affect the choice of treatment technique. The size and complexity of the surfaces to be treated are critical factors. Cars that should be anti-corrosion protected often have complex cavities whereas trains have large cavities. The production pace is also affecting the choice of treatment technique. Does the client produce 60 units/hour (common in car factories), or perhaps only a few units per day? Choosing the right treatment method require knowledge and experience of the different materials that are to be applied. We often work in close collaboration with the material supplier.


We use three main types of treatment techniques:

• Airmix (high pressure air mix): The material has a pressure of 30-150 bar and is mixed with compressed air (6 bar) in a mixing chamber. The mix is led to the nozzle where holes and slots distribute the mixture in different directions. This method is commonly used when applying anti-corrosion protection to cavities.

• Airless: Material pressure of 30-250 bar. The material is led through a carbide nozzle mounted on the tool and the spray gun. There are a number of different suppliers of nozzles that we use. The difficulty lies in choosing the right nozzle in combination with adjusting the right material pressure and using the correct spray gun.

• Extruding: Material pressure of 10-200 bar. The material is pressured sufficiently to slowly flow out of the nozzle. The nozzle usually touches the detail to be treated. To get the desired shape of the material we develop the nozzle ourselves.
