Connecting filter medium to base body involves pressing filter medium onto base body and melting body with laser beam via filter medium so liquid plastic penetrates supporting material

摘要

The method involves pressing the filter medium (1) onto the base body (4) with a pressure arrangement and melting the base body using a laser beam (9) passing through the filter medium so that a shape-locking joint is made between the filter material and the base body by liquid plastic penetrating the supporting material (2). A flat transparent plate (7) is used as the pressing arrangement.
