Abstract: A preferred transmission filter (10) includes a first flange (18) transparent to a laser beam (58) and includes a second flange (20) opaque to the laser beam (58) and meltable upon exposure thereto. The flanges (18, 20) are in registered, abutting relationship with a laser weld bead (62) at the juncture (44) between the flanges (18, 20) to provide a fluid seal circumscribing the filter (10). The preferred filter manufacturing apparatus (12) includes a laser (54) coupled to a robot arm (50) controlled by a programmable logic controller (52). The controller (52) operates the robot arm (50) in order to direct the laser beam (58) through the first flange (18) onto the second flange (20) and along the juncture (44) to form the laser weld bead (62).

Abstract: The invention is directed to a process for the laser welding of two filter half-trays made of plastic and used in automatic transmission oil filters, wherein two filter half-trays are placed one on top of the other and welded along their common edge using laser light, one filter half-tray consisting of laser light-permeable plastic and the other filter half-tray of laser light-impermeable plastic, and the laser beam is passed through the laser light-permeable filter half-tray along the position of contact with the other filter half-tray, striking the laser light-impermeable filter half-tray, and co-fusing of the two filter half-trays within the welding zone is achieved by light absorption of the laser light-impermeable plastic material.

Abstract: A plastic component including a plastic body having a first body portion and an integral tubular portion defining a tubular extension and a lip seal on the tubular body, the plastic body being formed in situ on the lip seal. The method of making the plastic component including providing a first mold cavity having a portion for defining the body of the component and a communicating second cavity for defining the tubular extension, positioning an annular lip seal in the cavity defining the tubular extension, and injecting molten plastic resin in the first cavity and the second cavity to define the plastic component with the lip seal positioned on the tubular extension.
