Plastics News senior reporter Bill Bregar gathered these plastics machinery items at the K 2010 show, held Oct. 27 to Nov. 3 in Dusseldorf, Germany.
Gravi-Dryer tracks resin consumption
After three years of development, Danish auxiliary equipment maker Labotek A/S introduced the Gravi-Dryer, a gravimetric drying system hopper.
The dryer's accuracy is plus or minus 0.5 percent, giving full control and tracking history of material consumption for each drying hopper. It ramps the airflow up and down according to the actual consumption, so you use only the energy required to dry the material you are using, said sales manager Thomas Ringheim.
Gravi-Dryer stores the consumption of each material, and of each processing machine, and the information can be easily retrieved, Labotek said.
Any material that is lost in weight, gets replenished right away, Ringheim said. The filling of a drying hopper during the ramp up method eliminates the risk of over-drying the material.
The filling of each Gravi-Dryer is fully automated, and adjusted according to material usage, with no need for any manual operation.
Ringheim said plastics processors are serious about lowering energy costs.
The trends are definitely moving in the direction when you have to measure what was sent to the system compared to what you consume, he said at K 2010.
Labotek is based in Frederikssund, Denmark. Its U.S. agent is V-Tech Engineering Inc. of Bluffton, Ind.

Uniloy Milacron/B&W sells electric unit at K
Uniloy Milacron Germany GmbH/B&W Blowmoulding Systems sold an all-electric UMS 12E.D blow molding machine, displayed at K-show, to HTP Hochwertige Pharmatechnik GmbH & Co. KG in Neuhas, Germany.
The sale marked the seventh UMS press the firm sold in 2010 and the third all-electric blow molder of that size, for applications from cosmetic to pesticide bottles in 4- liter coextrusion.
Power consumption, measured at K, averaged 25 kilowatts, on an hourly output of 2,130 parts vs. 42 kw needed for the same products running on a hydraulic version of the UMS.
The all-electric version uses the same clamping system as the hydraulic machine. The only changes are replacing all hydraulic cylinders by electric drives, according to the machinery company in Berlin.
The machines are made in Uniloy's plant in Policka, Czech Republic. Sales and service are done at the German headquarters.
Uniloy Milacron Germany is a unit of Milacron LLC.

Minibox chiller touts free-cooling option
Italy-based Green Box srl introduced the Minibox, a compact stand-alone water-cooled water chiller that sits beside the processing machine and boasts two integral temperature control units.
The Minibox chills and heats water in the temperature range of 20-200° F.
During cold months, it uses free cooling, to produce chilled water without operating the chiller, saving energy.
The unit's scroll compressors use R 410A refrigerant gas.
Water cooling provides extremely low noise levels, according to the company. The water pump, condenser and evaporator and heat exchanger for free-cooling are made out of stainless steel.
Having two temperature control units allow for one-zone only and/or two-zone heating and cooling, and/or integrated free-cooling, said Jose Garcia-Hernandez, operations director for the company's U.S. unit, Green Box America Inc. of Bensenville, Ill.
For cooling, Minibox can switch back and forth between using compressors in the chiller, or from adiabatic cooling through one of Green Box's closed-loop, rooftop cooling units using adiabatic cooling.

Rheo-Pro available for stack-mold use
Georgetown, Ontario-based Mold Hotrunner Solutions Inc. introduced a new application for its Rheo-Pro hot-runner systems: stack molds.
The Rheo-Pro iVG is an internally actuated valve gate with no external cylinder and no seals. All components are inside the unit.
Mold Hotrunner Solutions President Harald Schmidt said that, up to now, the company's Rheo-Pro has been in used in single-faced molds, but this is the first use in stack molds. The Rheo-Pro iVG nozzle is compact, using a back-to-back configuration, so the mold can be thin, he said.
It opens a new option for compact molds and complements all-electric machines, Schmidt said

AGR, Italian firm make software deal
AGR International Inc. announced a supply agreement with PET Engineering srl, the Italian firm that designs PET containers.
PET Engineering, based in San Vendemiano, Italy, will provide AGR's closed-loop blow molding control software, Process Pilot, as part of its container lightweighting services.
Process Pilot works with AGR's PETWall Profiler system, to monitor bottle material distribution in real time and adjust settings on the blow molding machine automatically. That makes it possible to maintain a very tight process window.
AGR International is based in Butler, Pa.
Separately, AGR said its 2010 acquisition of West Analytical Laboratories in Maumee, Ohio, brings a fully equipped, OSI 17025-accredited lab and experienced staff for glass and plastic containers. These tests include identification of contaminants, glue content of PVC and non-volatile residue content and identification.

Sensi-Sure grippers save part surfaces
End-of-arm tooling maker SAS Automation LLC showed the new Sensi-Sure grippers, featuring jaw closing adjustment, to protect parts from getting marred and end the binding of parts and sprues.
You set an adjustable screw for the desired jaw-closing position for your specific parts. An integrated jaw screw allows replacement of the jaws.
The sensing range covers a much larger area than previous models, according to SAS.
SAS also introduced Uni-Grip and Uni-Clamp gripper tooling. Uni-Grip is a universal system that allows for a precise gripper tool to be built with greater assembly flexibility, thanks to a channel-nut-free cross connectors and gripper mounting clamps that fasten with a new expanding channel-nut mount, rather than a standard channel nut.
Uni-Clamp can be mounted into the extruded nut channels on different brands and sizes of frame molding, so you can use frames currently in-house.
Also new is a GFD 1/4 Mini vacuum manifold, that fits right next to the cup, to keep vacuum directly on the cup. It has an integrated vacuum generator.
SAS is based in Xenia, Ohio.

Unicor UC320 targets medium-sized pipes
Unicor GmbH introduced an economical corrugator for medium-sized pipes, the UC 320.
The 320 replaces the UC 250, of which Unicor sold more than 100 machines around the world.
The UC 320 blends expertise from Unicor of Hassfurt, Germany, and the corrugator business of FrÃ¤nkische Rohrwerke GmbH & Co. KG. Unicor bought the corrugator part of FrÃ¤nkische in 2009.
Managing Director Klaus Kaufmann said the UC 320 is aimed mainly at the cable ducting and drain-pipe markets, for pipe up to 320-millmeters in diameter.
Benefits include 40 percent higher production speed, easy operation and quick tooling change, he said.
