Company introduces sheet take-off units
For in-line thermoforming, Processing Technologies Inc. has introduced a line of Compact sheet take-off equipment.
The take-off units are used with PTI's Trident series of coextrusion sheet equipment. The Compact unit conditions the sheet without completely cooling it, giving it enough strength to be transported to the thermoforming. Because of its small size, the system delivers sheet at an elevated temperature, increasing production and energy efficiency without sacrificing a quality surface finish, according to PTI in Aurora, Ill.
PTI is touting the quick-installation of the skid-mounted Trident extruder and the sheet take-off unit.
Other features include the new Uni-Rail Conveyor, with rails that have removable, reconfigurable idler supports.

Octagon displays new dual-lip air ring
Octagon Process Technology GmbH in Wurzburg, Germany, showed a new SmartLip dual-lip air ring, and a blown film control called ScenEx that can be easily customized.
With the SmartLip design, two air streams enable optimum cooling of the film, so the output can be increased by 30 percent over single-lip cooling rings.
Octagon said SmartLip is especially suited for making blown film by the short-neck method. The first air stream gently cools the film as it leaves the die, stabilizing the bubble. The second air stream strikes the bubble higher up, where the film is more stable.
Octagon also showed its ScenEx range of measurement and control systems for extrusion lines. ScenEx ensures uniform film properties by using lineal weight control with gravimetric dosing of additives and a width control. The company claims the technology increases output and reduces gauge tolerances.

Nissei Plastic unveils 2 all-electric presses
Nissei Plastic Industrial Co. Ltd. is introducing two all-electric, vertical-clamp injection presses, with series names TH and TD.
Features the lines have in common, according to Nissei, are:
* An alternating-current servomotor used for each function, so the presses save up to 80 percent energy compared with hydraulic machines, and run at 11 percent faster cycles.
* A swiveling injection unit, which makes it easy to clean the screw and heating cylinder.
* A very rigid die plate to minimize deformation.
Both machines use Nissei's NC9300T controller.
Nissei, of Nagano, Japan, said the presses come with a single-stage mold clamping system or a turntable.
The single-stage mold works well for hoop molding, such as the continuous molding of filters and relay terminals, because the upper mold moves up and down. The design also is suited to parts that require three-dimensional bending as a pre-treatment.
Another design, with two lower molds situated on a turntable, is aimed at insert molding.
Clamping forces range from 22- 88 tons for the TH series and 121-181 tons for the TD series.
Nissei America Inc is based in Anaheim, Calif.

SolveTech designs measuring profiler
The Precision Profiler from SolveTech Inc. is designed for off-line thickness measurement of blown and cast film.
The system uses the same proprietary capacitance technology SolveTech has used in its on-line gauges, but offers enhanced data management through its PR2000 software.
SolveTech is based in Claymont, Del.

SAS tooling clamp is injection molded
SAS Automation Ltd., which makes end-of-arm tooling for robots, has developed tooling clamps that are injection molded from long-glass-reinforced nylon with a small amount of titanium.
The clamp is used to mount a tooling component, such as a suction cup, to the frame of the tooling.
SAS has dubbed the product line Get a Grip NT.
The filled nylon part is light and strong. ``A major selling point for robots these days is their speed. The lighter the EOAT, the faster they can go without excessive wear,'' said John Westbeld, design manager for SAS in Xenia, Ohio.
SAS displayed the composite clamp at the K 2001 show in Germany. The firm has opened a sales office in Germany, in Karlsruhe.

Siemens touting low-cost controller
Siemens Energy & Automation Inc. is aiming its low-priced Siject controller at injection molding and blow molding machines.
Chris Vaniglia, plastics market development manager, said Siemens thinks the controller will catch on in the retrofit market. The company also is selling Siject units to machinery manufacturers.
Siject is based in Siemens' Simatic S7-200 programmable logic controller. Features include a ProTool operator face and Step 7 software which includes automatic sequencing, lubrication and purge cycle, digital outputs and a screw-cleansing program.
Siject also uses Siemens Step 7 software. Siemens' U.S. plastics controls operation is based in South Lebanon, Ohio.
