In the 1960s, the idea was born to replace the previously used wire helical carrier with a metal carrier. The metal stamping technique was therefore used to achieve this result. The carrier then had a certain flexibility which was necessary for the installation and cornering.
As early as 1962, LWB developed and manufactured an automatic table stamping machine and the associated tools to produce metal carrier. The department of stamped carriers for the rubber profiles was created.
Over the years, this business evolved significantly and has become increasingly important for the sealing and fastening functions of rubber extrusions. The large growth in this area and the associated increased space requirement made repeated relocations of the production necessary. At its present location in Altdorf near Landshut, STG is in position to cope with the increased volumes with its machinery.
The next important step was the development of lanced carriers. Lanced carriers allow for increased number of meters with the same material without sacrificing quality, can be produced much faster and more efficient and allow higher degrees of freedom in the installation of finished profiles in the vehicle. Again, the close cooperation with LWB machinery paid off for STG: The sister company took over the development of the lance machines. The entire know-how in this area therefore remained under one roof. Short development times, fast communication and complete independence from third parties are still a major strength of STG versus it’s competition.
