Mechanical crimping allows to combine dissimilar materials with the purpose to achieve a thermal, acoustic, magnetic or electrical decoupling. Montanstahl preferably uses a special glass fiber reinforced polyamide (GRP) as web material and solid metals like common mild steel and stainless steel for the flanges. Special alloys like bronze, copper and brass can be used as well for the flanges.
The process requires a precision U shaped adapter, which can be made from steel or stainless steel, which gets fused on the flanges. The fixing of the GRP web is achieved by a continuous mechanical crimping process, which squeezes the steel against the web. The result is a strong frictional joint. The thickness and the width of the flanges can be defined according to the technical requirement.
