Maplan heater cuts electric needs, costs
A seemingly minor change to the screw oil heating element on American Maplan Corp.'s profile extrusion lines reduced the amount of electrical power needed by 20 percent, to 7.6 watts from 9.5 watts.
In addition to reduced energy consumption, the improvement can increase heater life by 50-60 percent, with less machine maintenance, said Kurt Waldhauer, vice president of sales at the McPherson, Kan., company.
Waldhauer said Maplan officials noted brisk spare-parts orders for the heating element, and they figured the frequent orders indicated a relatively high part failure. Maplan and the heating-element supplier agreed that the lower wattage could give just as good a performance.
Available on new extruders and as a retrofit, the new heater is identical in appearance to the old model and it connects to the machine in the same way.

D-M-E lifters create deeper undercuts
Milacron Inc.'s D-M-E Co. said its VectorForm system of pre-engineered lifters doubles the undercut, giving angles up to 30 degrees and more.
An innovation of Takao Injection Mold Engineering, the lifter system offers design flexibility, since designers can incorporate undercuts that are twice as deep as previously possible, D-M-E said. Mold designers can cut their ejector stroke in half while maintaining existing undercut geometries.
VectorForm uses a slide base concept to greatly extend the lifter angle. The lifter rod is actuated from a sliding base instead of a static base in the ejector place.
A modular design allows ganging of multiple lifter systems to accommodate very large lifter cores, something D-M-E said was not possible with pre-engineered lifter systems.
Also new from D-M-E is its Multi-Parting Line system, which doubles the number of cavities on standard single-face molds. Applications include automotive, housewares, caps and closures, cutlery and electrical/electronic.
D-M-E is based in Madison Heights, Mich.

Smaller footprint on Indestep rotary press
Indestep International Ltd. of Middlesex, England, said its patented rotary injection units are a significant improvement over conventional nonrotary designs, providing a smaller footprint and savings in overall costs for the machine and tooling.
The Indestep molding press is based on an integral hot-runner system. That system allows injection of plastic straight into the mold cavities without the need for sprues.
The result is a measurable savings when compared with conventional machines that rely on multicavity hot-runner molds to make small and midsize parts.
Standard parts of the mold form part of the machine itself.
The Indestep machines are available in clamping forces of 50-100 tons.

Winder option means less shaft handling
Davis-Standard Corp., based in Pawcatuck, Conn., is offering an option on all its turret winders for film and extrusion coating that reduces shaft handling and related injuries associated with winders.
The option is available for less than $50,000 on Davis-Standard winders.
The new design features two arms for lowering and unloading full rolls into a cart.
One arm pivots away from the winder for removing the roll while the second arm holds the shaft in place, eliminating unnecessary lifting and simplifying unloading.
Davis-Standard said the integrated system consumes much less floor space than a separate shaft puller and cart.

Battenfeld presses offering Lubrimelt
Battenfeld GmbH of Meinerzhagen, Germany, is offering the Lubrimelt plasticizing unit on its TM and HM injection presses, to ensure reliable processing of self-lubricating plastics.
The unit is equipped with several grooves, distributed around the cylinder in the feeding zone, to ensure controlled transportation of material between the granulate and cylinder wall, even in the case of a low-friction coeffient, the firm said.
Also, the machine builds up high pressure in the feeding zone, so metering adjustments are possible in the melting zone even when wall slippage occurs because of insufficient shear speeds. The length-to-diameter ratio ensures the screw will melt materials completely.
Battenfeld of America Inc. is based in West Warwick, R.I.

Cannon technology marries TRW mold
Two sister companies under Italy's Cannon Group - Sandretto Industrie SpA and Windsor Kunststofftechnologie GmbH - have teamed with TRW Engineered Fasteners & Components to create a three-component molding cell.
The molding cell includes a two-component injection press from Sandretto's Series Nine Multi line, and a Windsor PlugXPress multicomponent retrofit unit.
In a single manufacturing step, a TRW mold is producing air grilles for the automotive industry with several individual components, fixed together but movable to each other. There is no need for secondary assembly. Cycle time is 40 seconds.
The PlugXPress unit is placed horizontally, in an L-shape, to the Sandretto press, which has a clamping force of 242 tons. The mold indexes 120 degrees for each shot.
Cannon is headquartered in Trezzano, Italy.
The U.S. unit for injection presses and PlugXPress is Sandretto USA Inc., headquartered in Cranberry Township, near Mars, Pa.

EGS Gauging shows two product lines
EGS Gauging Inc. launched two product lines: the E, for checking sheet extrusion and vinyl calendering lines, and Solution 21, for film and sheet manufacturers.
E combines scanner/sensor technology, advanced electronics and Wonderware software. The operator interface has been simplified so that operators easily can navigate a few intuitive displays.
Solution 21 uses a gauge that can be mounted on any of EGS' industrial scanning frames. Wonderware/Windows-based software runs the system.
EGS, headquartered in Bellerica, Mass., said Solution 21 is the ideal platform for extruded sheet lines, where large investments in gauging and control are not feasible.
Also new from EGS is a redesigned operator console and an improved scanning frame.
