Agr*TopWave shows quality-testing tools
Butler, Pa.-based Agr*TopWave LLC introduced three quality-testing instruments for plastic bottles.
The Preformer inspects PET preforms, at a rate of up to 22,000 per hour, for a variety of common defects such as leaks, flaws in the seal surface and visual defects in the sidewall and base. The machine incorporates two inspection modules in a single package - a camera-based inspection module for detecting sidewall and base defects and a leak detection module to check for seal integrity and leaks caused by holes or not enough resin.
Agr*TopWave also has added a feature called Vision to its PERWallplus vision inspection and thickness monitoring system. The camera-based system monitors sidewall thickness distribution and detects random defects - at speeds of up to 40,000 bottles per hour.
The company also said its Vision bottle gauge 7000 is now available, for laboratory use. The automated testing station works unattended, using a high-speed robotic handling system to move each bottle from a tray and place it on the testing surface.

StaMixCo LLC forms to make Bayer mixer
StaMixCo LLC was founded this year to make and market a new disk static mixer, licensed from Bayer AG's High Viscosity Technology Group in Germany.
StaMixCo has an exclusive, worldwide license. Bayer has used the technology at its resin manufacturing operations. Applications include injection molding mixing nozzles, extrusion belt blenders and hundreds of other uses in processing fibers, polymers reactive resin/hardener systems and more.
The mixer is based in the BKM mixer, which is marketed as the SMX mixer, which also was developed by Bayer and licensed to a static mixer supplier in the mid-1970s. The new Disk Static Mixer has the same structure as the well-known SMX, but its disk fabrication technique reduces the cost of manufacturing and gives higher strength. StaMixCo also can easily vary the number of crossbars, which keeps the basic geometric structure identical and minimizes the length-to-diameter ration in mixing.
StaMixCo has offices in Brooklyn, N.Y., and Switzerland.
The company also is offering a mixing nozzle for injection molding called the SMN, in diameters of 12, 18, 22, 27 and 40 millimeters for injection presses with screw diameters from 30-180mm.
StaMixCo also sells a melt blender SMB for extruders. The unit, which has no moving parts, mixes and homogenizes the polymer melt at the die. It eliminates differences in temperature and changes in composition. The SMB can be used on extruders with screw diameters from 25-240mm.

Camera-based system promotes mold safety
Automated Vision Technology Inc. of Colorado Springs, Colo., has rolled out a camera-based system vision device called MoldInspector.
The unit prevents molded parts from flashing or making short shots and getting mold closure damage from stuck parts and stuck ejectors. It inspects the mold before and after part ejection.
MoldInspector determines a pass/fail result for a given region of inspection. An input/output logic analyzer is built-in for easy timing and diagnostics.
Also new from Automated Vision: TrayInspector, which does in-line inspection of thermoformed trays. It detects pinholes and thin spots in real-time.

AccuRate Bulk has time-saving measure
AccuRate Bulk Solids Metering of Whitewater, Wis., said its Multicor Solids Flowmeter measures the weight of resin when it moves from rail car into the silo. The equipment saves resin makers the time and cost of continually going back and forth between the loading silos and the rail scales because the loaded car is either underweight or overweight.
After going through the extrusion and screening process, finished pellets are transferred through a tube inlet into the Multicor, which totals the weight of the pellets and moves the material through a vented air lock in a pneumatic conveyor line, then into the silo. The correct amount is automatically dispensed to fill one rail car.
AccuRate also said its line of volumetric and gravimetric Mechatron feeders have been installed in plastic/wood composite manufacturing facilities throughout North America. The feeder is well-suited for feeding fillers like wood flour, the company said.
AccuRate is a unit of Schenck AccurRate.

Kuhne announces screw, controller
Extruder maker American Kuhne Inc. has introduced a new barrier screw for fractional melt high density polyethylene, and a new process controller for extruders.
The touch-screen Aktive extrusion process controller provides a single location for setting and adjusting controls, intuitive process adjustment with graphic touch screen, computer-assisted creation and storage of unlimited recipes, coordinated control of drives, real-time monitoring of multiple process variables trends and alarms.
Aktive is designed for pipe, custom profile and tubing manufacturers that need more automated information to reduce scrap and improve efficiency.
In screw news, Edward Seward, director of process technology, designed the HP-2 barrier screw for fractional melt HDPE in high-pressure applications. Kuhne said the new HP-2 provides up to 20 percent more output than previous designs, when back pressure is 3,500 pounds per square inch or greater.
Seward said the screw is ideally suited for HDPE pipe, sheet, small profiles and blow molding where the processor is forced to live with a restrictive die situation.
The Norwich, Conn., company also introduced a low-cost barrel air-cooling system called Turbo Air-Cooling System, which has a high level of heat removal capacity approaching that of water cooling. The new design can hold existing barrel set points on extruders with screw diameters from 21/2 inches through 6 inches, in the vast majority of applications that require water cooling.
In another cooling-related development, Kuhne said its research has shown that its Even-Flow water-cooled technology gives a simple, low-cost modification to eliminate ``one-sided'' cooling that can damage water-cooled extruders. Kuhne documented this so-called ``siphon effect'' during an intensive study at its research and development laboratory. Problems happen at the plumbing ``T'' connection where the water flow is split to the left and right heater halves.
