Schreiner ProTech has expanded the application of its laser-based manufacturing process to include automotive thorax airbags. Previously only applicable to side inflatable curtain airbag wraps, the new and customizable Miniature Thorax Airbag Wraps technology can now be used for airbags that protect the thorax and pelvis of vehicle occupants. Airbags are covered by special wraps that must meet exacting safety specifications. The production of these covers has historically involved time-consuming processes such as the manual sewing of material to create sleeve-type wraps or costly plastic injection molding. Made of a nonwoven fabric, Schreiner’s Miniature Thorax Airbag Wraps are printed, laser-welded, and cut to size through a high-speed, one-step process that eliminates the need for complex sewing of the fabric parts, thus improving assembly process efficiency. Multilingual warnings can be conveniently and accurately positioned on the compact fabric part, enabling airbag manufacturers to flexibly tailor their products to fit customer needs no matter where they are located. Schreiner’s Miniature Thorax Airbag Wraps are 10 times smaller than their side airbag counterparts but leverage the same manufacturing process and materials.
