Teknor Color touts TekTuff compounds
Teknor Color Co.'s new polyethylene compounds for rotational molding allow property enhancement or downgauging by as much as 15 percent, according to the Pawtucket, R.I., company.
TekTuff materials cost the same as cross-linkable PE and advanced metallocene PE but they are tougher and stiffer, according to Teknor. Their properties allow them to replace cross-linkable PE in applications such as watercraft and containers where high chemical resistance is not an important property. They are recyclable and eliminate the need for cross-linking agents.

Ferro heat stabilizer targets wire, cable
Ferro Corp.'s new nonlead heat stabilizers are geared to wire and cable extrusion.
The mixed-metal powders are based on calcium/zinc chemistry. Therm-Chek nonlead stabilizers are available in grades suited to difficult plenum applications, general-purpose jacketing, appliance cords and high-performance uses.
The firm's Polymer Additives Division in Independence, Ohio, said lead-based additives perform well and are low-cost, but some compounders are looking for low-toxicity alternatives.

KM, Mold & Hotrunner make 56-cavity molds
Krauss-Maffei Kunststofftechnik GmbH of Munich, Germany, and Mold & Hotrunner Technology AG of Hochheim am Main, Germany, have developed a 56-cavity mold for PET soft drink preforms.
KM upped the cavity count from 48 to 56, while still using the same space, by reducing the pitch and modifying the control system and preform-removal robot.
Krauss-Maffei installed the new Petform 56 with an unidentified customer in March.
The company's U.S. unit is based in Florence, Ky.

Syncroflow extrudes plastics and rubber
Syncroflow tooling from Guill Tool and Engineering Co. Inc. can extrude plastics and rubber simultaneously.
The plastic can be run on the inside or the outside later, since Syncroflow tooling is designed with a barrier that insulates and separates the extruded materials from each other. The extra layer facilitates the processing of two materials with widely differing processing temperatures.
Syncroflow is available in diameters from one-eighth of an inch to 6 inches.
By using a single die for both rubber and plastics, instead of a normal two-step process or in tandem, Syncroflow provides excellent adhesion of materials in their molten state, according to Bill Conley, sales manager for Guill Tool in West Warwick, R.I. Also, there is less chance of contaminants being trapped between the layers of plastics and rubber.

Keller HCW offering film skiving machine
Keller HCW GmbH of Ibbenburen, Germany, is marketing a special machine that makes plastic film by the skiving process - a knife slices off a billet of plastics.
The film is reeled onto a mandrel using a precision machine.
Keller has added more optional equipment, such as an automatic partition of the film lengthwise, which allows it to be reeled onto separate mandrels. The company also added separate controls for the skiving and reeling tensions.

System 21 contains multiple languages
System 21 film monitoring equipment from Eurotherm Gauging Systems Inc. can speak Chinese.
Eurotherm of Bellerica, Mass., launched the latest version of System 21 at Chinaplas '02, held June 25-29 in Shanghai, China. The equipment is for companies that produce film and sheet, and coated and converted products that use a continuous web. The system now boasts a multilingual operator panel that supports the Chinese language, among several other languages and dialects from an on-screen menu. Users can change between different languages in seconds.
System 21 is based on Windows 2000 Professional and Wonderware softwares.
Eurotherm also has introduced a Roll Quality Management System as an option, enabling the System 21 to integrate roll information and quality data.

Software minimizes resin left in film line
Plast-Control Inc. said its Advanced Control System for film extrusion management and gauge control has new ``material minimizing'' software, called MMS.
MMS continually monitors and controls the amount of resin actually in the entire extrusion line, including the extruder, dosing and vacuum-loading systems. When enough resin is in the system to complete a job, MMS automatically shuts off the supply, so that a bare minimum of resin remains.
The feature significantly reduces material waste and cuts changeover times. Matt Bangert, general manager of Plast-Control, said the Newburyport, Mass., company developed MMS to meet demands for short runs and rapid transitions. Through the Plast-Control Central software networking system, the company can link all ACS systems in a plant via the Ethernet, to communicate all production data to management.

Comet hopper loader offers remote pump
Comet Automation Systems Inc. has introduced a hopper loader with a remote, three-phase pump, priced starting at $1,000.
The stainless-steel S-Series vacuum receiver can convey 1,650 pounds of material an hour. The receiver is remote from the pump, for a split design that ensures quick cleanup time and easy maintenance and function setting, the firm said.
The operator panel can be mounted on a receiver, as standard, or installed on Comet's M-Pump vacuum unit.
The S-Series hopper loader also is available with a glass material chamber, with a proximity sensor.
The M-Pump vacuum unit can connect to as many as three S-Series receivers.
The Dayton, Ohio, auxiliary equipment supplier will debut the S-Series at Plastics Encounter Indianapolis, scheduled for Sept. 17-19.

Schenck AccuRate picks up feeder line
Schenck AccuRate Inc. has picked up the SolidsFlow product line of feeders used by plastics compounders for feeding dry-chopped glass fibers.
The units use a one-piece vibratory feed-tray, specifically designed for glass. The design enables the natural matting effect of the fibrous material to seal itself within the feed tray - preventing flow and spillage when the drive is turned off.
Other features include no material arching or hang-ups in the hopper, minimized clumping, no need for flow-aid devices and no moving parts.
The flow rate can reach 3,000 cubic feet per hour.
The company is based in Whitewater, Wis.
