It took many years of experimenting before the first shrink joint was sent to Danish Technological Institute, and it was quite a struggle to get the first VA approval. H.L. Muffer ApS, therefore, contacted BIC Nord, which was a Danish counsellor company that helped with the proper counselling, in terms of several theoretical questions and problems. With their help, H.L. Muffer ApS succeeded in getting the first VA approval on April 25th 2000.
