New ink dispensers help laser Weld Clear parts. (Keeping Up With Auxiliaries).Laser welding of translucent parts is now feasible, thanks to a new laser-absorbent ink and specialized ink-dispensing systems from two suppliers working in partnership with the ink developer. ClearWeld, a process developed by Gentex Corp. in Carbondale Carbondale. 1 City (1990 pop. 27,033), Jackson co., S Ill.; inc. 1869. It is a railroad division point and the retail center of a coal-mining and farming area. Southern Illinois Univ. is a major employer. Memorial Day was inaugurated (1868) in Carbondale by Gen. John Logan. Giant City State Park and a wildlife refuge are nearby. 2 City (1990 pop. 10,664), Lackawanna co., NE Pa., on the Lackawanna River; inc. 1851., Pa., requires precise deposition of inks formulated to absorb near-infrared (NIR NIR - National Identity Register (UK) NIR - National Internet Registry NIR - National Inventory Report NIR - Near Infrared NIR - Near-Infrared Reflectance NIR - Net Interest Revenue NIR - Net International Reserves NIR - Net Irrigation Requirement NIR - Network Information Retrieval NIR - Nine Inch Richards (Nine Inch Nails parody band) NIR - No Individual Requirement NIR - Non-Immediate Allergic-Type Reactions NIR - Non-Ionizing Radiation) laser light. Previously, laser welding required one part to be infrared-absorbing, limiting it to only black or dark-colored parts. With ClearWeld, the laser passes through the clear plastic, but stops at the joint, where it is absorbed by the ink and generates enough heat to create a weld. The ink-dispensing equipment suppliers are Nordson Corp. of Duluth, Ga., and Xennia of Royston, Hertfordshire Hertfordshire (här`fərdshĭr, härt`–), county (1991 pop. 951,500), 631 sq mi (1,634 sq km), E central England. The county seat is Hertford, but Watford, Hemel Hempstead, Stevenage, and St. Albans are more important urban centers. The terrain is level except for an extension of the Chiltern Hills in the northwest., U.K. They have developed, respectively, a liquid spraying system and an ink-jet printer for accurate application of Gentex's inks. "They open the way for implementing our technology," declares LP Frieder III, marketing manager at Gentex. Nordson's Product Assembly Group offers a ClearWeld package consisting of a spray apparatus, tips, and syringes. Nordson also supplies robots and 3D motion-control tables required for precise product placement, ink dispensing, and laser manipulation in low- to medium-volume operations. For high-volume welding, Nordson offers customized tabletop work cells. Meanwhile, Xennia's XPS 9000 industrial inkjet system is specially designed to dispense Gentex's NIR-absorbing inks. An integrated IR lamp ensures efficient ink drying after deposition. Nordson: (800) 683-2314, www.nordson.com / productassembly; Xennia: +44 1763 24 6600, www.Xennia.com |
