NitroJection launches satellite control unit
Gas-assisted injection molding equipment supplier NitroJection Corp. of Middlefield, Ohio, has introduced a new, low-cost satellite control unit, for companies that need multiple controllers at several presses.
The NitroJection Satellite Unit comes with one, two or four outlets to feed nitrogen gas into the machine nozzle or gas pins in the molds. The unit controls the timing and pressure profiles of the gas injection. An Allen-Bradley SLC 503 runs the NSU.

Leading Edge offers nozzle, molding tip
Leading Edge Products Inc. of Sterling Heights, Mich., has developed two new products for gas-assisted injection molding.
A self-actuating nozzle has only one moving part. A stainless-steel spring device activates the shut-off. The nozzle has no hydraulics or pneumatics. Leading Edge said the nozzle, which screws into standard barrel thread, can be used for gas-assist or conventional molding.
The company's self-aligning injection molding tip assembly has three parts that screw easily into the end of any nozzle. The assembly aligns the sprue bushing and nozzle tip and compensates for as much as 0.04 inch misalignment in all directions.

Granulators recycle large PE, PVC pipe
Neue Herbold GmbH has a new line of big granulators, the SR series, for recycling vinyl and polyethylene pipe up to 20 feet in length and 3 feet in diameter, and with walls as thick as 3 inches.
Smaller sizes of scrap pipe can be stacked on top, or placed inside larger pipes for higher output.
Until now, pipe makers had to saw large-diameter pipe manually, or pre-size pipe using a low-speed shredder, according to Neue Herbold, based in Sinsheim, Germany.
SR granulators have a horizontal feed channel, which contains the pipe and meters the infeed into the rotor. The design eliminates the need for building a pit or an elevated platform to feed pipe through a side chute. The solid drum rotor has four to 10 blades that cut against two or three stationary knives. A single-drive motor runs the rotor.
Neue Herbold's U.S. unit is New Herbold Inc. of Sutton, Mass.

Barron introduces pelletizing extruders
Barron Inc. of Atlanta has added a line of Plasmac pelletizing extruders to its film-scrap reclaim and fluff conveying systems.
The Plasmac converts thin-wall thermoplastics, such as film, flake and nonwoven materials, into pellets. A short screw means material has a short heat history.
Barron is offering two types of Plasmac extruders: the Compact series for reclaiming in-line trim and the Integra for off-line, loose scrap. Maximum outputs range from 55-1,540 pounds. Screw diameters range from 2-4.8 inches.
Tel. (404) 325-7340, fax (404) 321-3870.
PolyDrive users pick from four languages
Gebruder Haake GmbH of Karlsruhe, Germany, has developed the PolyDrive, with models that work as extruders or mixers.
The machines can be used for quality control and to make sample batches.
An operator display shows processing conditions in a choice of four languages.
