Brown announces two new controllers
Brown Machine LLC of Beaverton, Mich., announced two controllers for thermoforming machines: the Series 4.0 and Level 2.
Both are flexible, adaptable, easy to maintain and use open architecture, Brown said.
Brown offers the controllers as standard on all its CS- and SRS-brand continuous thermoformers and higher-end cut-sheet thermoforming machines. They are optional on all other Brown thermoformers and trim presses.
The 4.0 controller, which has a touch-screen monitor, uses an Allen-Bradley SLC-500 programmable logic controller. An Ormen motion controller provides servo movements and real-time timing. The controller comes with an industrial-grade personal computer, running Windows XP. Other features include Ethernet communication to secondary controllers and a modem.
The heater control on the 4.0 allows ovens to run on open loop, with a percentage timer, or closed loop using feedback from thermocouples. Temperature accuracy while running closed loop stays within plus or minus 2Ã¸ F, with most types of heaters, Brown said.
The oven menu shows the actual oven's dimensions, so an operator can set up zone profiles relative to the sheet position on screen. The controller displays color-coded alarms, warnings and other types of information.
The Level 2 cut-sheet controllers include the same display, recipe storage, diagnostics and other features of the 4.0. All process parameters for platen movements, rotate and lift-table functions communicate through the PLC and variable frequency drives.
Open-loop platen systems are repeatable within plus or minus 0.03 inch. An optional closed- loop system, using Allen-Bradley's Control Logistics software, is repeatable within plus or minus 0.005 inch.
Heater controls are open loop, percentage-time controlled. Each zone can be set in 1 percent increments or a two-second time base. Brown said time-based programs allow for unlimited forming routines, which are only restricted by movement capabilities of the machine.

Moditec srl offering new Masher version
Moditec srl is ready to Mash and Mash again.
The company said a double version of its Masher rotational cutters enable the new Titan Plus slow-speed granulator to grind large parts such as television cabinets and housings for computers or printers.
Traditionally, Moditec made the Masher available only in a single configuration. The company developed a twin Masher because some customers needed to grind up bulky parts. The Masher cutters are located inside the hopper and on top of the cutting chamber, and they grab the parts and push them down. Since the Masher rotors run at a different speed than the main cutting rotor, all the pieces are moved into the cutting chamber.
Titan Plus granulators run at 25 revolutions per minute, so the machine does not create dust.
Moditec also offers its Integrated Metal Detection technology, which shuts down a beside-the-press granulator within 40 milliseconds if metal enters the cutting area - saving the machine from damage.
Marennes, France-based Moditec's U.S. distributor, Plastec North America Inc., is in Miami.

Granutec Inc. touts granulator/separator
Granutec Inc.'s auger granulator/separator, called the Auger-Matic, fits under an injection press or thermoforming machine. The company claims the combination is ``quicker than a picker.''
A standard central lubrication setup allows maintenance while the unit is running. Feeding options include feed-roll systems and special feed hoppers for reclaiming rejected parts.
The Auger-Matic has a tangential feed cutting chamber and an auger entry engineered for continuous granulation without jamming. An optional package includes knives for running abrasive and glass-filled materials.
Granutec of East Douglas, Mass., also introduced its TFG2530, with a throat size of 25 inches by 30 inches and horsepower ranging from 50-100. The machine recycles bulky, blow molded parts like bottles, jugs and milk cases.

Comet Automation spotlights products
Comet Automation Systems Inc., which makes auxiliary equipment in Dayton, Ohio, unveiled its vision system and tiny dryer for micromolded parts:
* Mounted on an injection molding machine, the PE-300 vision system checks parts for flash, short shots, contamination or changes on the part surface. A new hand-held monitor has a 6.5-inch screen pendant and weighs less than 3 pounds. Screen resolution is six times greater than the previous model, so the PE-300 can sense ultrasmall parts or small product details, using just 0.03 second of scan time.
Comet also upgraded the product with a high-detectable camera and an infrared-light source.
* The half-liter Micro dryer was running on a Sumitomo micromolding machine at NPE 2006 in Chicago. The Micro hopper sizes range from 0.5-3 liters. Comet has combined modern compressed- air technology with a compact modular design, so the dryer can work with very small parts.
