Milacron Inc. executives took pains to show their earth-friendly side at NPE2009.
The message is all about sustainability and responsible manufacturing, said Robert Strickley, Milacron's marketing director.
Sustainability is the No. 1 issue when it comes to the plastics industry, he said at the show.
Company officials reviewed Milacron's technology offerings at a June 22 news conference at the Chicago show, held June 22-26.
At NPE, Milacron announced major new options on the all-electric Roboshot S2000i-B series of injection molding presses
Fanuc Ltd. of Japan makes the Roboshot presses, and Milacron distributes them in the U.S. under a long-standing agreement. A 165-ton Roboshot molded parts during NPE2009.
The new enhancements are available immediately on Roboshot presses of 55, 110 and 165 tons, with the rest of the line to be completed later this year.
All new Roboshots have lower bases, with a stronger design. The 110- and 165-ton machines have a more-compact footprint, thanks to improvements in the electrical system. The newly designed base is more rigid than conventional square tubing designs, so the base suppresses vibration.
The enhancements include high-transmission rubber belts that generate reduced noise under high-speed operation; a new high-speed ball screw for long life and noise reduction; and a central lubrication system in the clamp area. Optional features include an anti-vibration package with vibration-dampening machine mounts and rubber mounting for the power cabinet frame. The result, according to Milacron, is a faster, quieter machine with less vibration.
The Roboshot also features a ServTek TCS radiant barrel heater, now designed for small-diameter barrels. Made from ceramic-fiber insulation, the TCS can reduce energy consumption by 35-50 percent compared with conventional heater bands. For the first time, the firm is offering TCS heater systems for barrels with diameters of 5.8 inches.
Milacron also introduced the Vitesse, a German-made injection press with a French name, the word for speed. The Vitesse is built in the company's Ferromatik Milacron plant in Malterdingen, Germany.
The Vitesse, available in 230, 330, 440 and 550 tons, is a further development of Ferromatik's Cap-Tec press, introduced in 2006 for molding caps and closures. Strong demand for Cap-Tec machines led the company to come out with an XL-version for all types of packaging, such as lids, buckets and in-mold labeling applications.
The Vitesse covers the entire range with a single machine. The Vitesse also covers other industrial sectors such as the consumer goods industry, said Robert Burzler, Ferromatik sales and marketing director.
Milacron sold a Maxima MM310 coinjection press off its show floor to Bemis Manufacturing Co., a coinjection molding specialist in Sheboygan Falls, Wis. The 310-ton press can do seven processes in a single machine, including coinjection and controlled breakout molding of soft/hard parts.
Milacron also announced but did not show in Chicago the PowerPak, a direct-drive electric injection press that gives the customer the option of all-electric power or a hybrid press blending hydraulic and electric technology. The new model is available as an all-electric on all four axes of motion clamp, injection, part ejection and the screw drive or as a combination of the ejector and injection axes as hydraulic.
The clamp and screw drive remain all-electric on all model configurations.
Andy Stirn, market development manager, said the PowerPak offers higher performance than Milacron's Powerline NT series of direct-drive machines, which Milacron continues to make. The company is aiming the PowerPak at high-speed, low energy molding of thin-wall packaging, caps and closures, and medical and consumer products.
Milacron claims PowerPak is the only electric-based machine with stack mold capability, optional tie-bar supports and an optional, integrated greaseless carrier system.
Other new machines
Uniloy Milacron's partner FGH Systems Inc. brought to NPE an all-electric Uniloy blow molder designed by B&W Blowmolding Systems in Berlin. Once the mold is closed, the machine consumes no energy. The machine only uses energy to close the mold and weld the parison consuming much less energy than a hydraulic blow molding machine.
Uniloy Milacron North America has a new, smaller Uniloy UR65 reciprocating blow molder, designed for customers needing low- to medium-volume productivity, reduced energy use and a cost-effective machine.
Cincinnati Milacron Extrusion Systems has installed a Weingartner screw-cutting machine at its Wear Technology plant in McPherson, Kan. The Weingartner significantly increases screw manufacturing capability.
We use the new machine primarily as a milling machine, with its focus on twin-screw manufacturing, but we also have whirling capability, said David Thiessen, engineering manager at Wear Technology. This new machining capacity has increased our length capability, allowing the manufacture of screws in excess of eight meters in length.
The Weingartner also expands the operation's product line outside of plastics, in areas such as pump rotors and screw pumps.
Milacron also has a one of the high-speed screw cutting machines at its main base of operations in Batavia, Ohio, near Cincinnati.
