Diamond screws fit on other extruders
Diamond America Corp. of Tallmadge, Ohio, introduced a line of single-screw extruders that are compatible with screws from other extruder makers.
President Tom Allen said many Diamond America customers are running one extruder brand.
``To change to a different brand of extruder would mean that they would have to stock a spare screw for each brand,'' he said.
The first extruder in the series is a model TL250 with a screw diameter of 2½ inches and a length-to-diameter ratio of 2411 However, the screw-compatible extruder is available in all sizes. The machine can be equipped with either alternating-current or direct-current drive and motor.

Bruckner producing cast PP film lines
Bruckner Formtec, a subsidiary of Bruckner Maschinenbau GmbH of Siegsdorf, Germany, known for its film stretching lines, now provides equipment for making cast polypropylene film.
Cast PP has evolved from a niche market to broader applications such as packaging, personal hygiene, synthetic paper and barrier film for pharmaceuticals and food, Bruckner said. The film has excellent optical and mechanical properties and competitive pricing, according to Bruckner,
The company's cast PP lines cover a film width from 3.5 yards through 7 feet. Output reaches up to 4,400 pounds per hour.
The cast film lines use Bruckner's PLC controller. The company's U.S. operation, Bruckner Inc., is in Greenville, S.C.

Munson's SCC cutter controls particle size
Utica, N.Y.-based Munson Machinery Co. Inc. said its SCC-30 screen classifying cutter cuts hard, soft and fibrous materials into controlled particle sizes, with minimal fines, at high throughput rates.
The cutter features a patented rotor design with dozens of cutter blades attached to a helical array of staggered holders, dubbed ``interconnected parallelograms'' that shear oversized materials against twin-bed knives.
The cutter has a 30-inch wide throat. It can be fitted with 60 parallelograms with 120 cutter inserts.
``Unlike conventional granulators containing a small number of angled rotor blades that slice materials into strips in scissorlike fashion, the SCC cutter is configured with cutter blades along the entire shaft, with no gaps between blades, making total contact with the product,'' said Charlie Divine, Munson's marketing manager. That means the SCC cuts material uniformly with little to no heat generation, he said.

Guill Tool touting its coextrusion dies
Guill Tool & Engineering Co. Inc. of West Warwick, R.I., said its Series 220 coextrusion die makes advanced profiles and seals of thermoset and thermoplastics for aerospace, automotive and construction products.
The tooling can extrude product sizes of half an inch to 21/2 inches. It offers simultaneous directed material for a single product or multiple families of products that have identical material requirements and must be extruded in different end-use sizes.
The extruded material prevents degradation and stagnation of material in the die. Material flow can be directed to various areas of the substrate.

Epco Machinery LLC introduces bushings
Epco Machinery LLC now makes split movable-platen bushings with weld rings, a way to replace bushings without removing the tie bonds.
The bushings are made of 660 bronze metal, instead of molded fiber. Epco drills, taps and assembles the weld rings.
Worn bushings can cause machine problems like sagging, lubrication problems, leaking of the clamp ram packing and platens out of parallel alignment,
Epco, of Fremont, Ohio, also can perform replacement work of knock-out plate bushings.

Cumberland adds to granulators' features
Cumberland Engineering has added adjustable rotor knives and replaceable knife seats on the rotor for its 3200 and X series granulators.
The company in South Attleboro, Mass., said adjustable knives eliminate throughput loss from cutting circle reduction because of knife wear and resharpening. The change allowed Cumberland to make enhancements: close the rotor knife tip-to-screen tolerance, for film and thin sheet applications, and increase throughput on applications involving pre-shredding of material.

Modern Process unveils Gran-U-Lizer
Chicago-based Modern Process Equipment Corp. said its Model 88 Gran-U-Lizer virtually eliminates fines and provides uniform particle size.
The machine's continuous, ``roller-style'' grinding method improves yields, reduces waste and can eliminate downstream classification systems.

Control-Rite to make Epcon equipment
Epcon Gas Systems Inc. announced that Control-Rite Inc. of Sterling Heights, Mich., will manufacture the new Epcon Advanced III equipment for gas-assisted injection molding.
Epcon, of Rochester Hills, Mich., said the Advanced III has the first multifunction controller that can direct an injection press with gas-assisted molding or in jobs that do not require gas-assist. The controller can run two machines at the same time. Features include gas-assist pressure profiling control of up to four outlets, a 12-gate sequencer and a 16-zone temperature controller.
``Should a molder lose a gas-assist job or have the volumes reduced, they'll no longer be stuck with that investment sitting idle,'' said Epcon President Jon Erikson.
