Economizer offering two new granulators
The Economizer USA unit of ACS Group is offering a line of small, soundproof granulators called the ESC Series, and a new ESP line of granulators for pipe and profiles.
The machines are under the EconoGrind name.
ESC has 20-inch rotor diameters, available in widths of 20, 28 or 50 inches. ACS said that range of rotor sizes is ideal for general-purpose granulating. The small machine can be transported with a forklift.
Knife adjustment is performed outside the unit before installation, by using a fixture that comes with the granulator.
Another EconoGrind granulator, the ESP, has a nearly level feed hopper so long pieces can be fed easily.
The machine controls the feed rate, which reduces the risk of blocking.
Economizer is based in South Attleboro, Mass.

Battenfeld package upgrades bag maker
Eastern Packaging Co. Inc. upgraded some older equipment at its Lawrence, Mass., plant by adding a 31/2-inch blown film Contracool extruder and a 10-inch die package from Battenfeld Gloucester Engineering Co. Inc.
The bag maker said it boosted output by 40 percent in its low density polyethylene film production, improved quality, and now can run 100 percent linear LDPE for the first time.
The company also is using Battenfeld Gloucester's new UltraCool air ring, designed to be more user friendly, with more repeatable settings.
Eastern Packaging's 120,000-square-foot factory houses eight blown film lines, a number of converting machines, bag machines and printing presses.
The company generates more than $6 million in sales from PE, cellophane and polypropylene bags.
Eben Andrew, senior blown film product manager for the Gloucester, Mass.-based machinery maker, has helped all three generations of Eastern Packaging, according to Eastern President Erik Curtis.

Monitor can measure individual film layers
Facts Inc., which makes extrusion control systems in Cuyahoga Falls, Ohio, introduced a real-time, in-process, film-thickness monitor and analysis system at the PlasTec West show in January in Anaheim, Calif.
Processors accurately can measure the thicknesses of individual film layers and make adjustments during production.
The thickness analyzer features Equispec technology from Equitec International Inc. of New Ellenton, S.C. It simultaneously monitors the thickness of multiple layers of thin films, on the same substrate, at multiple points across the web.
Facts also rolled out a real-time system to monitor and analyze color in extruded plastics. Using the Equispec Color Analyzer, the probe is designed for a number of applications, including vinyl, floor and wall coverings, decorative laminates and reinforced fibers and textiles.

Sprue-actuated valve made for hot runners
Plastic Engineering & Technical Services Inc. said its pressure-actuated shut-off valve reaches zero vestige with a single drop, without a valve-gate cylinder, for easy use and less maintenance.
The shut-off valve eliminates the need for secondary pieces or equipment, resulting in reduced assembly time. Interchangeable springs maximize shut-off pressure, to benefit mold makers and injection molders making material changes.
Plastic Engineering & Technical Services of Auburn Hills, Mich., also has introduced angled drops, to improve the performance of hot-runner systems. According to the company, the drop design reduces shear and cavity pressure. The design can run parts on a press with 1,000 or 1,500 tons of clamping force, compared with a standard, 3,000-ton machine.

Berstorff process hardens barrel bores
Berstorff GmbH has developed a new heat-treatment process for the rectangular barrel housings of its ZE UTX twin-screw compounding extruders.
The result is a much harder surface on the barrel bores.
An inductor moving along the center axis of the bore induces electrical eddy currents in the part to be hardened - which, because of the electrical resistance in the metal, causes the metal to heat up.
Then the metal is cooled.
Bertstorff's U.S. unit is in Florence, Ky.
