Battenfeld EM press expends less energy
Battenfeld of America Inc. said the first of its EM line of all-electric presses, a 176-ton model, was made available to U.S. customers in July. A 110-ton EM will follow in September, and other sizes will arrive early in 2003.
Battenfeld of America, based in West Warwick, R.I., will keep an inventory of EMs in the United States for quick delivery.
Battenfeld GmbH of Meinerzhagen, Germany, introduced the EM at the K show last year. Thomas Lenz, president of Battenfeld of America, said the EM uses half as much energy as comparably sized hydraulic presses. Lenz said the machine design results in as much as 60 percent more nozzle-contact force, 17 percent more ejector force, 18 percent faster injection speed and 15 percent more injection pressure than competitive machines.
Battenfeld also is releasing more details on the injection unit. Two electric motors, with direct-drive spindles situated parallel to the injection unit, transmit rotary power into linear motion without belts. The company said precise electrical control of the injection unit ensures a seamless transition from the injection phase to packing phase - for minimal deviation between the programmed and the actual injection profile.
In automotive news, Volkswagen AG's factory in Braunschweig, Germany - which already has 110 molding machines of various brands, topping out at 880 tons - bought a 3,520-ton press from Battenfeld GmbH.
The big machine molds dashboards using sequential injection molding. Battenfeld installed the press last fall. Battenfeld planned the complete line, including a Suhling robot, grippers, a transportation line with a cooling station and magnetic clamping system.
The hydraulic, three-platen press has electric screw rotation.
The Braunschweig plant makes underbody parts and systems.

Littleford improves compounder, cooler
Littleford Day Inc. of Florence, Ky., said its low-cost mixers/compounders and coolers offer full clamshell opening, from front to end.
Higher surface polish makes them easier to clean and improves cooling. The mixing action from a mechanically fluidized bed separates particles to prevent stratification while putting them into constant movement and contact with the cooler's water-cooled walls.

InductaMetals barrels guaranteed for life
Chicago-based bimetallic barrel supplier InductaMetals LP is announcing a guarantee for its wear-resistant IDM-Ultramax barrels - for the life of the barrel, for as long as the original purchaser owns the injection press or extruder.
For injection molding, Inductametals guarantees the barrel will not wear more than 0.01 inch diametrically for barrels with an inside diameter of less than 100 millimeters, or 0.015 inches for barrels of 100mm or more.
For IDM-Ultramax barrels used for extrusion, the guarantee stipulates the barrel will not wear more than 0.015 for barrels with an inside diameter of less than 100mm, or 0.02 inches for barrels larger than 100mm.
If the barrel exceeds the allowable limit, the company will elect to replace or repair the barrel, or refund the purchase price.
InductaMetals said processors using 30-60 percent filled resins report that their IDM-Ultramax barrels have lasted three to five times longer than the tool-steel or furnace-cast tungsten carbide bimetallic barrels they replaced, showing only negligible wear.

Stretch blow molding produces PET cups
Mitsui Machine Technology Inc. is pitching a new way to make PET cups - stretch blow molding - on a machine produced by Frontier Inc. of Ueda City, Japan.
Frontier's rotary, double-axis draw blow molding system has two main components: a heating section and a blow molding unit, which shapes a heated PET preform into a cup.
The all-electric machine can produce 240 cups per minute.
The blow forming method gives a high vertical draw, which gives a high rate of axiswise draw, improving thickness distribution and enhancing oriented crystal density.
The company claims the cups are 40 percent stronger than similar-size cups manufactured by vacuum forming or one-stage molding.
Mitsui Machine of Glendale Heights, Ill., is offering the Frontier machines to North American customers.

Belvac unit produces wide-mouth container
Belvac Production Machinery Inc. has introduced a machine to trim and finish wide-mouth PET containers made from standard narrow-neck preforms: the DTF 400 rotary trimming and burnishing machine.
The DTF series of machines incorporates Belvac trimming technology, ensuring burr-, sliver- and step-free containers with diameters of 50-110 millimeters.
The Lynchburg, Va., company also developed a DT/FT rotary trimming machine that can finish 200 PET tennis ball containers a minute.

Optical bottle sorter detects color, resins
MSS Inc., a Nashville, Tenn.-based maker of optical sensing equipment, calls its new, high-volume, plastic bottle-sorting device the Aladdin Sorting Machine.
The device can sort both by resin type and color, all in a single machine.

ACS Group debuts controller, dryers
ACS Group of Wood Dale, Ill., announced several new products:
* A Whitlock conveying controller, the VacTrac Series VTC4/32, is a four-pump, 32-station controller with an easy-to-use Panel View 600 touch-screen. Other features including an Allen-Bradley SLC 500 programmable controller, power output of 115/1/50-60 and a 24-volt direct-current control output.
* Whitlock's new line of machine-side, machine-mounted and multiple-hopper dehumidifying dryers for injection molding, extrusion and blow molding. The T Series provides high capacity in a smaller footprint.
ACS offers 25 new base models that it said can be arranged into hundreds of possible different combinations of dryer and hopper, and multiple hopper configurations.
The dryers come with a choice of two controls based on desiccant bed temperatures vs. time or dewpoint.

Witte Co. pelletizer integrates functions
When installed on the recirculation loop of underwater pelletizers, the Witte 400 pelletizing line from Witte Co. Inc. integrates dewatering, drying, cooling and screening in a single machine.
Witte of Washington, N.J., designed the 400 for a major global compounder.
The unit features a vibrating dewatering screen that removes surface water from the pellets and returns the water upstream, for reuse.
The mechanical system minimizes the need for thermal drying.
In the fluid-bed drying section, the Witte 400 uses the company's vertical airflow design to dry pellets at an air velocity of 600 feet per minute, removing fines and off-spec material.
A screening process further separates rejected pellets.

Software regulates speed incrementally
Atlanta-based Process Control Corp. has introduced a new software that it claims allows the extrusion line speed to ramp up and down in increments, maintaining perfect gauge and layer distribution over the entire line.
The feature is for the company's Gravitrol control system and Gravimetric blenders.
At each line-speed change, the system learns the weight loss of the extruder and then calculates the needed extruder speed for the next line-speed step change. The process continues until the final desired speed is reached.
