Downstream system for low-output use
American Leistritz Extruder Corp. offers a new cast-film downstream system for use with its ZSE27 twin-screw extruder, for a laboratory or small-output environment.
A typical system includes a flexible lip flat film die, cast-film take-off unit, edge pinner and torque winder.
The system produces film samples of one-half mil to 10 mils thick, and as wide as 12 inches.
Leistritz of Somerville, N.J., said the downstream equipment can be used with any brand of single- or twin-screw extruder.

Fast Heat features electronics, runners
Fast Heat Inc.'s Electronics Division and Hot Runner Division introduced several new products.
From the Electronics Division:
New standard features for the Symphony 2000 Series hot-runner controller include the ability to do historical analysis trending, storing data for all 96 zones, and a decision support system that displays a quick report when a problem happens, describing the problem and giving possible solutions and remedies.
The Digi-Mold ID, which stores recipes for use in mold changes.
A Conductor EF module that plugs into standard hot-runner mainframes.
Two-zone conductor series control system, as an alternative to larger mainframes when only a few zones are needed.
Two new Maestro displays, with four digits and three digits.
From the Hot Runner Division:
Elite Series Bushing with multiple tip configurations for molders running large parts. It also is suited for high-temperature engineering-grade resins.
For molders running small parts, the company offers two new bushings: Precision Series and Micro Point Series. They allow center-to-center distances as close as 1.38 inches for the Precision Series and 0.75 inches for the Micro Point Series.
The Elmhurst, Ill., company also offers a new user-friendly Electronic Design Manual for mold design that operates on AutoCad software.
Fast Heat also is touting its new rapid delivery program, with two-or five-day shipments through Fast Track Program and 10-day delivery on specially designed electric heaters.

Spirex Corp. V-Mixer gets high shear rate
Spirex Corp. has developed a V-Mixer Screw to produce a higher shearing factor for more complete dispersion mixing.
A patent is pending. Spirex said V-Mixer differs from other screws because it is ground rather than milled and polished.
V-Mixer achieves intense chaotic mixing action by creating a high shear rate and a side-to-side movement of the flow, as well as an up and down movement. By controlling the depths of the channels from deep to shallow and creating a nearly continuous side-to-side flow, Spirex said, V-Mixer gives a streamlined, free-flowing mix with no dead spots.
Spirex is in Youngstown, Ohio.

Controller handles 24-zone hot runner
Eurotool Operations BV of Gravendeel, the Netherlands, is offering a version of its Hi-Q temperature controller for a 24-zone hot-runner system.
Digital readout for the controllers is clearly and compactly arranged in a single rack, according to the company.
A new boost function increases the temperature of the whole hot-runner system to above the preset nominal temperature for a preset period when production begins, a time when the injection mold and hot runner are not in thermal equilibrium. That ensures the plastic is completely melted.

Sterling emphasizes downsized products
Sterling Inc. is getting small, by offering several compact products.
Sterling has expanded its Vision series of temperature controllers with the Sterlco Model 4016M Vision Oil Temperature Control System. The smaller-footprint unit controls processing temperatures as high as 450° F. Pump sizes range from 1-2 horsepower. Flow rates are 10-24 grams per minute at 30-50 pounds per square inch.
Also new: Model 4411 Vision Compact Temperature Control System, which controls resin temperatures to 300° F.
The Micro Vision System, Model 442, is a compact temperature controller that handles temperatures to 300° F with 15 grams per minute at 20 psi.
New glass-fiber-reinforced cooling towers provide cooling capacity from 50-200 tons. They feature induced draft design with vertical air discharge.
Milwaukee-based Sterling also introduced a hand-held Sterltech STS Controller. It can store more than 100 sequences.
From Sterling's Ball & Jewell line of scrap recovery systems comes Vision BPV68 Series beside-the-press granulators, with a roll-out, reversible screen and dual-feed, tilt-back hopper available for both front feed or robot feed. The compact Vision VG1634 granulator has a 40-horsepower motor.

Wayne coextruders for close melt inlets
Wayne Machine & Die Co. is making Yellow Jacket coextruders for processors running coextrusion dies that have closely located melt inlet ports.
Each ``hive'' contains two or more Wayne extruders, designed to work together to coextrude wire, tube, sheet, blown and cast film, monofilament and fiber-optic sheathing. They share a control panel and base, but each is individually adjustable on the base.
Yellow Jacket Hive is available with extruders that have screw diameters from three-eighths inch to 6 inches. Sizes can be mixed according to needs of the product.
Wayne is based in Totowa, N.J.
