Scientific nabs patent for Left Hook mixer
Ron Klein, president of Somerset, N.J.-based Scientific Process & Research Inc., has earned patent number 6,152,592 for his Left Hook mixer.
The mixing screw features a repeated pattern of raised, L-shaped elements, arranged in rows at right angles from one another. The elements face upstream, with a curved, concave contour that intercepts and disrupts the melt flow, forcing it downstream. The mixer provides a high degree of turbulence without the excessive, damaging shear normally needed to obtain a high level of mixing action.

Vulcan offers coiler, air wiper for extruders
Vulcan Machinery Corp. of Akron, Ohio, introduced two pieces of extrusion downstream equipment, an air wiper and a coiler.
The dual WRU series water removal unit removes water from high-speed strand extrusions, after it leaves the cooling process and prior to granulation. A remote air knife removes most of the cooling water. Then a vacuum is applied to remove any residual moisture. Vulcan said the device is 40-50 percent more efficient than using a positive air-pressure knife alone.
The custom SLC series coiler can simultaneously process four independent reels mounted on a common, differential-type winding shaft. A guide separates incoming profiles before coiling.

Gasmaster process offers exact injection
Gas Products Inc. of Sterling Heights, Mich., said its Gasmaster process injects precise volumes of nitrogen gas into the hot melt.
A touch-screen controller allows quick setups and the storage of recipes.

Colonial ups potential of multicavity molds
Colonial Machine, which makes molds for PVC pipe fittings in Kent, Ohio, has developed a way to make injection molds with more cavities.
Traditionally, according to the company, molders ran four-cavity molds. The new ``stand-up'' designs allow the molder to get eight to 12 parts from a mold of a similar size, doubling production.

Accu-Feed debuts pneumatic loaders
Accu-Feed Engineering of Norwalk, Ohio, has introduced a line of pneumatic loaders.
The series comes in two models. One mounts directly at the throat of the machine, while the other has a four-bolt pattern flange to mount directly to the resin hopper. Both models can convey material at a rate of up to 1,000 pounds an hour.
Accu-Feed can customize either version to match specific customer requirements.

Koch metering unit allows direct feeding
Werner Koch Maschinentechnik GmbH said its KE-M metering equipment puts color concentrates directly into the feeding area of the screw of an injection press or extruder, via a free inlet.
It is mounted directly on an adapter flange, usually in combination with a conveyor for new material.
Three control units are available, based on time, speed or a percentage of the shot weight.
Koch, which makes mixing, dosing, conveying and drying equipment, will show the KE-D at K 2001 in Dusseldorf, Germany, in Hall 10, Booth A-37. The company is based in Pforzheim, Germany.

Hunkar buys TriData, updates control kit
Hunkar Laboratories Inc. has acquired a bar-code equipment supplier, TriData Technologies.
Both companies are based in Cincinnati.
Hunkar is known for its process controls and monitoring software for plastics manufacturing. TriData is a 10-year-old developer and integrator of bar-code product systems.
Terms were not disclosed.
TriData will operate as a wholly owned subsidiary of Hunkar. TriData products and services will be sold through Hunkar regional managers, Hunkar's independent representatives, TriData sales reps and on the Hunkar Web site, www.hunkar.com.
Hunkar also said it has improved its SPC-Pro 5, a statistical process control kit for injection molding. Enhancements include continuous updates of actual values, with color coding; instant access to trend charts; updated parameters in real time during data logging and graph sampling; and the ability to use multiple overlaying curves to compare deviating molding parameters.
Tinius offers melt indexer, software
Tinius Olsen said its MP600 melt indexer, for extrusion, offers automated testing controlled by a personal computer. The testing instrument also does automatic flow rate measurements of up to three different loads in one test.
The Willow Grove, Pa., company also introduced Test Navigator software for use with its S-series of benchtop Universal testing machines or floor models equipped with the Model 398 Indicating system.

Automated bundles automation systems
Automated Assemblies Corp. is bundling a sprue picker robot, a granulator and a hopper loader into a package called Express. The price is $12,900.
The Express 3000 is the first product offering from Automated Assemblies outside of its core line of robots and automation systems. ``Many of our customers have indicated that they would like to see a turnkey type of system from us that would integrate our automation capabilities with material recovery,'' said Norton Kaplan, national sales manager for Automated Assemblies, in Clinton, Mass.

Sonitek presents rotary staking unit
Sonitek Corp. of Milford, Conn., has developed a two-position rotary heat-staking machine.
A two-position rotary table allows the operator to complete assembly in the loading station, while the machine is simultaneously staking another part. Other features include optical-touch palm buttons to reduce operator fatigue and caster wheels so the machine can be moved.
A quick-change feature for the upper tooling assembly lets the operator change the head assembly with no need for extra tools, even while the assembly is hot. The dial-plate also is easy to remove, so the technician can change part-holding fixtures fast.
A pneumatic pre-clamping assembly keeps the part from moving.
In another recent development, Sonitek introduced a line of ultrasonic welders built by Branson Ultrasonics Corp. exclusively for Sonitek. The S-800 series welder adds to Sonitek's line of heat-staking and thermal press machines.

Herrmann units get a digital upgrade
Herrmann Ultrasonics Inc. is going digital.
The company's new Dynamic generators for welding machines replace machines with analog components that are subject to aging and wear, according to the company in Schaumburg, Ill.
Analog-based welders also have manufactured-in tolerances, which can lead to inconsistent results. The output signals on the digital units can be calibrated, so they remain precise and consistent over time.
Dynamic generators also can recognize the resonance frequency of the converter/booster/horn-stack operations, automatically adjusting them to its start-up characteristics. Weld horns with a very narrow frequency band can be run because of a digital-frequency-tuning feature.
Also new from Hermann is a Dialog touch-screen controller, run by a personal computer. No special knowledge is required to set up the Windows-based controller.

Aqua system cuts cooling cycle time
The Aqua Breeze gives rotational molding a breath of fresh - and cold - air, according to J.E. Adams Industries Ltd.
Aqua Breeze uses a series of fans and high-pressure water, driven through a group of atomizing nozzles. The nozzles pump out tiny water drops, a cool fog that ``flash evaporates.''
J.E. Adams, of Cedar Rapids, Iowa, claims Aqua Breeze can reduce the cooling cycle by 20 percent.

EMI offers lighter, sturdier conveyors
EMI Plastics Equipment Inc. of Wickliffe, Ohio, said its aluminum direct-drive conveyor is about half the weight of standard EMI steel conveyors but rugged enough to withstand heavy use.
The AD conveyor is available with many EMI options, such as soft drop zones, indexing packages, variable-speed drive and adjustable side rails.
