Akron Extruders can build, ship in 3 weeks
Akron Extruders Inc. is picking up the pace: The Canal Fulton, Ohio, company announced it will build and ship four of its models in three weeks or less.
Each machine is built to order. Included in the offer are the M-PAK 150 and PAK 200, 250 and 350 extruders. The machines range in screw-diameter size from 11/2-31/2 inches. The barrels' length-to-diameter ratio is 24-to-1. Akron Extruders offers them with either resistance aluminum band or cast finned heaters.
Akron Extruders President David Kattan said market forces drove the change. ``This three-week option will allow processors to better schedule purchases of equipment to correspond to their production requirements,'' Kattan said. ``We are seeing a growing trend in the industry to postpone capital equipment purchases until there is production in-house to support the purchase.''

Bell Labs to license new welding method
Lucent Technologies' Bell Laboratories unit wants to license a new welding technique it uses to assemble ABS telephone handsets.
Lucent has hired Competitive Technologies in Fairfield, Conn., to market the technology to other companies.
Wil Jacques, Competitive's vice president of marketing, thinks the technology could apply to other plastic products, from toys to automotive interiors.
The process starts with insert molding. A tapered pin is molded into one of the parts, and a mating boss is molded into the other. The parts are positioned in fixtures and forced together at very high speeds. Frictional heat melts the plastic on the mating surfaces, welding the two parts together.
The welding method uses no ultrasonics, no vibration and no adhesives.
Bell Labs received U.S. patent No. 4,997,500 in 1991.
