Arburg Inc. of Newington, Conn., has introduced a new MB Series of lower-cost injection presses with open-loop controls and clamping forces of 28-220 tons, within its existing M Series. The machines differ mainly in their control technology. MB controls use a simpler, open-loop version of the Multronica closed-loop system used in the M Series.
Arburg also announced it has added a pivoting clamp as an option to its Allrounder C Series of injection molding machines.
The clamp, known as the U (universal) option, allows vertical positioning of the clamping unit, which is hydraulically raised from the standard horizontal position to the vertical plane.
The U option had been available only on Arburg M Series machines in clamping forces of 28-94 tons. Now it can be ordered for 33-, 44- and 55-ton 270C models with shot capacities of 2.08-5.57 ounces.
Bekum featuring in-mold labeling
Bekum America Corp. of Williamston, Mich., now offers in-mold film label applications for Bekum H-line blow molding machines.
The label inserter technology, with electric servo motor controls, assures accurate label placement with high efficiency for as many as 12 cavities, according to Bekum. The technology now is being used in more than 15 twin-station Bekum H machines in around-the-clock production.
Newbury Industries Inc. is re-introducing its H60-550 FS/HP high-speed injection press to the thin-wall closure market.
The 550-ton press, with a Toggle Ram clamp, is available with either a reciprocating or fixed-screw injection unit. The machine also has a two-stage injection unit and an integral accumulator system, according to the Newbury, Ohio, company.
Extrusion Dies Inc. has developed new quick-change lip inserts for flat dies that it claims can allow product changeovers 50 percent faster than the conventional method of replacing the entire lip assembly.
Named Advanced Lip Technology, the inserts are designed for use with EDI's Fast Gap automa-tic die-gap adjustment system.
EDI is in Chippewa Falls, Wis.
A line of oscillating models in Battenfeld Gloucester Engineering Co. Inc.'s Autoprofile air ring system minimizes gauge variation in blown film production, the Gloucester, Mass., company said. The air rings are designed to work with oscillating dies that some film processors prefer for gauge band randomization.
Battenfeld of America Inc. of West Warwick, R.I., is offering a hydraulic model of its modular CDC/CDK Series injection molding machine, equipped with Battenfeld's Unilog Tc40 closed-loop controller.
In April, Nissei Plastic Industrial Co. Ltd. will begin worldwide sales of its NS Series of tiny injection presses. Nissei started selling the machines, with clamping forces of 11, 22, 44 and 66 tons, in Japan last November and displayed them at NPE '94 in Chicago. Nissei also has established a subsidiary in Bangkok, Thailand, called Nissei Plastics (Thailand) Co. Ltd.
