Wipf AG wins the SPE Award
The Gasbag is an elementary component of the newly developed active suspension system that provides unmatched ride comfort, excellent dynamic handling, and new offroad functions. The custom-designed multilayer laminate features very low nitrogen permeability, reliably segregates oil and gas spaces, and assures superb gas density paired with excellent mechanical and chemical stability in the attenuation system.
The high-tech pouch consists of a laminate with a thickness of about 200 microns, a layer of specially alloyed aluminium foil and several layers of various polyamide films. This unique combination of various films in the laminate with a matching sealable polyamide filling port achieves extremely high mechanical, thermal, and chemical stability.
The first-time use of a pure polyamide laminate consisting of five different layers with aluminium imposes new challenges on the manufacturing method and the process technology. The world’s first pouch facility with automated induction sealing technology optimally solves the special challenges of polyamide materials with reliable processes. The underlying technology defines new benchmarks and higher standards in the production and conversion of flexible laminates.
