Extol Inc.'s InfraWeld uses infrared energy to weld plastic components to the surface of an automotive headliner — an alternative to using hot-melt adhesive in retaining head-impact-criteria components, wiring harnesses and other items on the B surface of headliners.
To prevent marking on the highly aesthetic A surface, the InfraWeld relies on tightly controlled positive air pressure to achieve the force required to executive strong, consistent spot-welds instead of a “punch” or other device to compress and bond the semimolten surfaces.
Extol of Zeeland, Mich., said it makes welding equipment, custom machinery and automated assembly equipment, and also does system integration.
Extol's partners in the headliner assembly method are Trim¼Quest LLC of Grand Rapids, Mich., which makes overhead systems and poly¼urethane headliners, and Oakwood Group of Dearborn, Mich., which developed Safety Plastic sheet with thermoformed, cone-shaped depressions for auto applications.
