13. High frequency welding
High Frequency (HF) is a popular manufacturing method for watertight construction.
The process uses coated (TPU) fabrics by heating up the material on the inside using high-frequency electromagnetic energy to fuse the two materials together (the materials must be coated with TPU); suitable materials are nylons, polyesters, with an increasing use of recycled materials.
OSM has developed highly complex hybrid solutions to bond molded plastics to TPU coated fabrics and all requisite machines and tooling for assembly.
