New recycling system produces PET sheet
Erema North America Inc. has introduced a new recycling system for in-line production of PET sheet from ground bottle stock.
The machine eliminates the need for separately predrying the material.
The new design includes a powerful vacuum at the densifier that handles predrying and crystallization with minimal energy use.
The sheet line uses an Erema TVE extruder and the company's Laser Filter.
Although it is designed specifically for ground, washed PET bottle stock, the system can be used with polypropylene and polystyrene. The Topsfield, Mass., company also offers a machine to make fibers.

Milacron adds press, enhances extruders
Product introductions from Cincinnati Milacron Inc. include a 120-ton size for its Vista Sentry injection molding press and a Material Enhancement Delivery System on its CM92 twin-screw extruders.
Milacron has added a 120-ton press to its line of Sentry machines, which had come in clamping forces of 35, 55 and 85 tons. The press features tie bar spacing of 17.1 inches by 17.1 inches and a shot size from 2.27-11.8 ounces.
MEDS increases the material drop temperature and improves mixing before the material enters the extruder. Milacron claims the system can increase output by 25-30 percent.
The CM92 extruder is designed for firms that extrude PVC pipe, profiles, siding, sheet or pellets.
Milacron's Plastics Technologies Group is based in Batavia, Ohio.

Color system analyzes sheeting, siding, trim
Hunter Associates Laboratory Inc. has developed its on-line SpectraProbe XE Color Management System, which analyzes color across the width and length of a product.
HunterLab of Reston, Va., said the spectrophotometer is well-suited for measuring plastic sheeting and vinyl siding and trim.
A fixed-point system stays permanently positioned over small width products such as siding. For wide sheet, a dual-point and traversing system automatically retracts the sensor when triggered by run end, sheet or product breaks.

Three-roll stack aids small production runs
Davis-Standard Corp.'s Killion extruder business has developed a heavy-duty horizontal three-roll sheet stack for short production runs and research and development.
The roll stack is for calendering, cast film, embossing or sheet.
The top roll is interchangeable, so processors can use a chrome-plated calender roll for sheet, then change to a rubber roll for embossing or laminating, the Pawcatuck, Conn., company said.
The unit, KDS-H14, is suitable for PET sheet and polyolefin cast film. The rolls measure 16 inches wide by 12 inches in diameter.

Inclined hot runners save time, money
Eurotool Operations BV offers a new series of inclined hot-runner nozzles as standard equipment.
Eurotool said that, by inclining the hot-runner nozzle in the mold up to 30 percent, a mold designer can locate the cavity exactly in the center of the mold, but also use an eccentric gating system.
Examples where that type of gating would be needed include injection molded lenses, or parts that are hollow or open in the middle.
Before, it was necessary to use costly indirect gating, using a manifold system and straight hot-runner nozzle.
Screw-in nozzle tips can be changed quickly, allowing injection through a pin gate or through a tunnel or film gate in the parting surface.
Eurotool of Gravendeel, the Netherlands, is owned by Dynisco Inc. of Sharon, Mass.

New software stores injection mold data
Industrial Software Co. of Hilliard, Ohio, has created Mold Manager software for storing injection mold inventory and production data.
The software, which costs $1,499, creates a history for each mold showing dates of repair, production on the press and its location. Other features include reports that show mold repair costs, and calculation of part weight, pounds of material used and hourly production rates.
