New Schenck feeder is compact, flexible
Schenck Process GmbH, which makes feeders for the compounding industry, rolled out its ProFlex C, designed with flexible troughs to fit into a wide range of spaces in a factory.
The auger and paddle are driven separately, which optimizes material flow, the company said.
The augers remain off-center, allowing up to eight feeders to be installed. The setup of both the drive and augers can be adjusted during installation.
The containers are easy to clean and access for service work.
Schenck Process is based in Darmstadt, Germany.

Latest mixers suited for larger extruders
StaMixCo Technology AG of Dinhard, Switzerland, introduced a larger SMB-R extrusion static mixer melt blender, with models designed for extrusion flow channels with nominal diameters of 6, 7, 8 and 10 inches.
The company said the new sizes are well-suited for large extruders with very high output and for the production of foamed products.
The mixers are made of stainless steel. StaMixCo has eliminated the stagnating zones at the wall where the mixer bars enter the surrounding support ring.
StaMixCo also introduced its GXF disposable static mixer - now made of injection molded polypropylene and glass-filled nylon, instead of more-expensive machined metal. The GXF is designed for hard-to-mix viscous mixing/dispersing applications in two-component systems for urethanes, adhesives and varnishes.
The GXF uses the X-shape geometric static mixing structure. The unit is good for mixing and dispersing two fluids with large differences in viscosity or extreme flow-rate ratios that normally would require a very long string of helical static mixing elements.
The company's U.S. operation, StaMixCo LLC, is in Brooklyn, N.Y.

Cabot system readies microscopic samples
Boston-based Cabot Corp., a specialty chemicals and materials company, has created a new method of preparing samples for microscopic dispersion tests specified by ISO 18553, which requires tiny button samples.
When these are cut manually with a scalpel, the most-common current method, it is hard to get the right consistency of size and weight. Cabot has automated the process, and made it repeatable.
First, a punching machine, fitted with six calibrated cutters, stamps out the buttons on a glass microscope slide. A second slide is placed on top, and the two are pressed together in a second machine, under high heat. Six exact samples are created in less than two minutes.
Cabot also recently announced it has joined the Gulf Plastics Pipe Academy as a member. The nonprofit trade association is being created to promote the use of plastic pipe in the Middle East.
``The decision to form the GPPA acknowledges that plastics pipe manufactured and installed to the appropriate standards is the best solution for the management of the region's scarce water resources,'' said Cabot Vice President Sean Keohane, who is the general manager of GPPA. ``The early history of plastic pipes in the region suffered as a result of poor-quality systems.''
Cabot has developed a number of carbon-black grades specifically for pressure pipe.

Bielomatik presents noncontact welding
Bielomatik Leuze GmbH + Co. KG of Neuffen, Germany, has presented two new noncontact methods for welding plastic - infrared and hot-gas convection.
Infrared welding offers several advantages, including fast heating using radiation energy, avoiding the formation of loose particles that occurs with vibration welding, clearing up uneven places on the weld and reducing the size of the welding bead. Infrared also uses less energy, as it is only heating during the heating process.
Hot-gas welding is a horizontal, two-stage welding process that channels the hot emissions from the fuel specifically onto the weld seam.
Bielmomatik also introduced a hybrid welding machine, the K 3217, that combines vibration and infrared welding. The company also makes laser-welding machines.
The company's U.S. unit, Bielomatik Inc., is in New Hudson, Mich.

Moog rolls out valves for molding machines
Moog Inc.'s Industrial Group has introduced innovations in electrical and hydraulic systems for injection molding presses and blow molders. The company also offers a new control valve for large-tonnage injection presses and a new line of servovalves.
Moog said its motion control for large blow molding machines helped usher in all-electric blow molders, with high mold carriage speed and high clamping forces. The new Moog nonlinear electric drive mechanism can generate high speeds comparable to hydraulic power, but with a 50 percent energy savings.
For injection presses, the company offers a Moog servodrive, a servomotor and a nonlinear injection unit. The system can deliver injection speeds of up to 1,000 millimeters per second.
The new Moog servovalves are called the D672, D639 and D638. The line of valves controls speed and force during injection, accumulators and nozzle-touch, ejectors and core pulls.
Moog also introduced an Axis control valve, with integrated software, for controlling the clamping units on large injection molding machines. The digital valve allows the press to adhere precisely to a defined motion profile, for a high level of repeatability.
The Moog industrial operations group is based in East Aurora, N.Y.

Illig thermoformer boasts speed, quality
Illig Maschinenbau GmbH & Co. KG of Heilbronn, Germany, introduced a new thermoforming line with the emphasis on speed and product quality.
In a recent demonstration, Illig pumped out drinking cups on an RDM 70 thermoforming line, running 40 cycles per minute. Also new: the RDK 90 automatic forming/punching machine.
Illig said the new, third-generation machines and tools make it possible to reach cycle times for polypropylene, which have so far been achieved only in polystyrene forming. The tighter processing range for PP requires special heating technology in automatic, roll-fed thermoformers. Heating rolls located in a closed cabinet heat the sheet uniformly.
The RDM 70 does pressure forming and punching in one station. A new PH 54 stacking device can do single-row cup stack discharge, for automatic post-processing. For speed, the turning device, with a suction box on both sides, picks up the cups from the forming machine and forwards them to a stacking cage.
Illig calls the RDK 90 the first thermoforming line designed for in-line operation and use of end packers - producing large batches in up to 55 cycles per minute. After parts are formed and punched, steel rule dies, integrated into the forming tool, separate the parts from the web.
The company's North American headquarters, Illig LP, is in Cohasset, Mass.

Guill tooling system cuts down on waste
Guill Tool & Engineering Co. Inc. introduced the Series 2000 tooling for extruding plastic and rubber, which the firm said cuts cost and gives labor savings by reducing the amount of waste material generated.
Guill has developed a patent-pending combined die and reservoir system. Material flow from the die to the compound is delivered in the exact amount required for each quadrant of the profile. The tooling also can be run in coextrusion, to combine more than one material.
Guill, based in West Warwick, R.I., used computational-flow-analysis software to create the more-precise tooling.
``The output of polymer is actually shaped long before it gets to the tip of the die,'' said Bill Conley, sales manager at Guill. ``With this technology, the polymer cannot return to its original shape. We calculate the amount of required material throughput for your profile and design the polymer flow channels to meet these requirements.''
Once the tooling is engineered, Guill runs the design through the flow-analysis software to guarantee the calculations are accurate.
Guill also introduced the FlexiSpiral line of crosshead and inline dies, the Equaflow II tooling for extruding plastic and wood composites, and the Micro-Mini II small extrusion tooling.
