Yellow Jacket units offer more flexibility
Yellow Jacket Multiphase twin-screw extruders from Wayne Machine & Die Co. are very flexible machines developed to compound multiphase ingredients simultaneously in a laboratory.
Typical lab twin-screw extruders deal with simple one- or two-phase ingredients, according to the company in Totowa, N.J.
The Multiphase extruder can handle the introduction of solid, liquid and gas ingredients, and gas extraction, at the same time. It uses segmented barrel sections and ports, allowing changes to be easily made to the process and to the ingredient sequence, according to Wayne.
The machine can run a wide range of thermoplastic compounds, including mineral- and glass-filled, color and modifier masterbatch, alloys, flame-retardant, anti-bacterial, ultraviolet-light-stabilized, wood-filled, foam and devolatized compounds.
Standard screw diameters are 19 millimeters, 25mm, 32mm and 50mm. The typical length-to-diameter ratios are 36-1 to 52-1, and longer when appropriate.

Black Clawson nabs patents for winder
Black Clawson Converting Machinery Inc. has received U.S. and international patents on its winding technology for high-speed slitting and winding of large-diameter rolls of film and other materials onto small-diameter cores.
Called the Advanced Technology SurfaStart, or ATS, the winder eliminates the speed and deflection challenges posed by in-line slitting and winding of that type of roll- and core-size combinations.
The materials can be wound up to 62 inches in diameter, at production widths up to 220 inches. ATS can wind at speeds up to 2,500 feet per minute on 4-inch cores and 4,000 feet per minute on 7-inch cores.
Black Clawson is based in Fulton, N.Y.

FIN EX offers smart control for extruders
Want to give your extruder some smarts? Check out the Extruder Intelligence System from Factory Intelligence Network LLC.
The FIN EX monitors production parameters from extruders that do not have the built-in capacity to collect data. The parameters include barrel temperature, temperature set points, screw speed, extruder amps and pressure.
The system includes a control panel with a color touch screen and a small programmable logic controller, which replaces the extruder's legacy temperature controllers.
The company, based in West Berlin, N.J., also introduced its Factory Intelligence Network system Version 3.8, which captures and records data from extrusion and other plastics processing lines.
Factory Intelligence Network was formed in 2003 by Automation & Control Inc., an automation systems integrator and electrical contractor.

Automa's Apex unit uses less floor space
Automa SpA of Bologna, Italy, said its Apex continuous extrusion, shuttle blow molder has a narrower design to take up less floor space. Bottles are discharged from the back of the machine.
Other features are proportional valves with the clamp moving on horizontal linear guides and a horizontal clamp stroke for fast and precise movements - even though the length is similar to long-stroke machines.
Automa's new controller is called the A-3MC. Modules for outputs for industrial personal-computer connect through a field bus.
The A-3MC's operator panel has a 15-inch, color touch-screen monitor, mounted on a swivel arm at the front of the machine.
Automa also said another new Apex machine, the AT 255D, uses all the best features of the Plus AT 07D continuous extrusion shuttle blow molder, with a larger horizontal stroke and the new A-3MC controller.
Automa's North American agent is Moldpro Inc. of Burlington, Ontario.
