Laser welding of membranes in the textile industry

Wiper motor housing

Membranes are permeable by certain substances. In engineering, they are used in all kinds of ways. In wiper motor housings, they enable pressure equalization. The membrane can be permeated by air but not by liquids. The challenge when joining membranes is to avoid affecting the fine pores in the active zone and to prevent damage to the membranes, which are usually very thin. The contour technique is used for this application because the heat effect during the joining process is minimal, thereby avoiding damage to the membrane.
