RJG mold identifier for use with eDart
RJG Inc. has released a mold identifier - model ID/LX1-S - that mounts to the mold so the tool can use the features of RJG's eDart System for mold identifying and job starts.
The unit can be mounted on either the moving or stationary mold half. It recognizes each mold as it is placed into an injection press. The mold identifier gets power and communications through a micro-connector that links it to the eDart.
If a mold does not have Lynx cavity-pressure sensor, the mold identifier allows eDart to ensure that the right mold is in place before a job runs. That offers a safeguard if an operator forgets to select the correct mold when starting a new job. The operator also does not have to select templates and setup data manually, said RJG of Traverse City, Mich.
Another new product from RJG is the Lynx delta pressure sensor, which can be mounted on the machine or the mold. The sensor measures the difference in coolant pressure between the mold inlet and outlet, giving information about the part cooling capability and consistency provided by the cooling system. Alarms can be set that allow problems to be detected in cooling lines, such as blockages or line failures.

China's PLC market expected to double
From 2003-08, China will double in size as a market for programmable logic controllers, which run automated factory equipment, according to a study from ARC Advisory Group
ARC of Dedham, Mass., said the Chinese market for PLCs will reach a compounded annual growth rate of 14.1 percent a year over the five-year period - even taking into account a decline in PLC prices. The market was about $370 million in 2003, ARC said.
Factories in China are using export revenues to invest in new technology. ARC said China's automation sector has grown by more than 20 percent a year.
ARC senior analyst Himanshu Shah said several factors are driving the Chinese PLC market. Power from the Three Gorges and Yellow River generation projects will ease energy constraints for further manufacturing growth. The outsourcing trend by multinational corporations setting up China production also fuels automation. And a surge in engineering education will support broader understanding of machine controls, while the booming machine tool market will continue to gobble up more PLCs, Shah said.
The report is called ``Programmable Logic Controller Outlook for China.''

WinTXU design tool uses TXS software
PolyTech has introduced WinTXU software for compounders and others that want to design a screw configuration for modular, co-rotating twin-screw extruders.
Extrusioneering International Inc. distributes PolyTech's WinTXU in North America. The design tool uses PolyTech's TXS simulation software's database of more than 70 commercial extruders. The user assembles a virtual extruder from a library of screw and barrel elements. The software lets the designer see the location of mixing elements with respect to the barrel openings.
PolyTech is in Branford, Conn. Extrustioneering of Randolph, N.J., is a distributor and consultant for twin-screw extrusion technologies.

Firms ally to provide front-end systems
Toronto-based Future Design Inc. has formed an alliance with Dual Spiral Systems Inc. of Hamilton, Ontario.
Future Design makes the Saturn air ring for blown film, and Dual Spiral builds dies and supplies barrier feed screws designed around a resin's melting behavior. The firms will provide blown film makers with complete front-end systems for monolayer and multilayer film. Dual Spiral Systems makes dies from 1-55 inches, and from one to 11 layers.

Guill says DualFlo can increase output
Guill Tool & Engineering Co. Inc. said its DualFlo tooling system increases tubing extrusion output by 40-50 percent vs. single-head systems.
DualFlo employs two identical heads joined by a specially designed metering valve to give an extruder dual output. The die can add multilayer or multistripe extrusion capability.
Guill Tool of West Warwick, R.I., designed the tool for tubing makers. Features include a fixed center or patent-pending FeatherTouch adjustment in the die holder. FeatherTouch is a cartridge-style ball assembly that does not need the retaining screws loosened for adjustments. The system seals to eliminate leaks between deflectors, and allows for easy self-alignment, the firm said. Dual Flo uses oil or water for integrated cooling.

MeltFlipper maker moves into larger HQ
Beaumont Technologies Inc., maker of the MeltFlipper melt rotation system, has moved to a larger headquarters in the same city.
The new headquarters is three times larger than BTI's previous site in Erie, Pa., said President John Beaumont. He credited growth and increased interest from custom and captive molders as the reason for the expansion.

Macchi devises way to recycle edge trim
Macchi SpA of Varese, Italy, has developed a way to recycle edge trim on blown film lines.
The stand-alone system, called Recotrim, moves the trim to a hopper, where it falls into a co-rotating twin-screw extruder. The scrap is melted and forced through a strand extrusion die. An adjustable-speed cutting system converts the strands into pellets, which are air-cooled using a vortex system, then transferred to a device for additional cooling.
The portable recycling unit can repelletize up to 90 pounds of material an hour. Macchi's North American headquarters is in Guelph, Ontario.

Kistler Instrument updates DataFlow
Kistler Instrument Corp. has updated its DataFlow process-analysis software. Type 2805A optimizes injection molding production quality, according to the Amherst, N.Y., company.
DataFlow improves the performance of cavity-pressure sensors and compensating sensor electronics. The software acquires data, creates statistical reports and visualizes the process.
Also from Kistler, for volume molding applications: miniature piezoelectric sensors using a simplified wiring hookup to speed installation and repair. Multiple cavities that require several sensors can be installed easily with single-wire cables, reducing mold costs, according to the company.
