Plastics News correspondent Michael Lauzon and staff reporter Nina Ying Sun compiled these briefs from the Plast-Ex show May 1-3 in Toronto.
Sturdell Industries doubling factory size
Mold and tool steel supplier Sturdell Industries Inc. is moving to a bigger facility and adding equipment to keep up with growing sales.
The Rochester, N.Y., firm is doubling space to 40,000 square feet by relocating to a plant behind its previous building. It also is adding saws, horizontal computer numerically controlled milling machines, grinders and other equipment, according to Sturdell sales director Scott Smith.
Rather than just sell steel flats and rounds, Sturdell can do preliminary working of the shapes to save mold-maker customers time and effort.
In addition to a range of steels, Sturdell offers services such as plate squaring, rough pocketing, eye-bolt holes, creating grooves and boring.
Canadian firm shows new line for molding
Progressive Components Canada Ltd. featured new components for clean room molding in its FrictionFreeT line. On display were roller pullers, wedge pullers and mechanical pullers for parting line sequence control. Angle pin rollers for side action eliminate wear, said sales manager Innocente Fabbro. Also new are slide retainers and standard ejector pins, said the Windsor, Ontario, company.
Milacron series adds two new press sizes
Milacron Inc. announced two new sizes in its Roboshot injection press line. It added 17- and 33-ton presses to its S2000i-B series introduced last year. The new presses feature wider tie-bar spacing and greater mold capacity than previous models, according to the Batavia, Ohio, firm. They also feature higher injection velocities and more rigid injection units.
Smart Cart contains tooling, instruments
Reko Automation & Machine Tool showed its new Smart Cart to hold tooling and instruments for secondary operations alongside processing machinery. The cart features welded frame construction, fork-lift tubes, safety guarding and controls cabinet. Bar-code reading, vision systems and part- marking systems are among the cart's options. It is designed to work with an array of Smart Cart Tool Paks also supplied by the Tecumseh, Ontario, company.
Dyna-Purge debuts purging compound
The Dyna-Purge division of Shuman Plastics Inc. debuted a new purging compound with dual-action scrubbing power.
Fast and efficient, Dyna-Purge M is the most versatile of the company's 10 formulations. Depew, N.Y.-based Shuman also highlighted new ABS compounds.
Available in utility black, black, white and grey, the ABS materials feature notched Izod impact strength of 5 foot-pounds per inch and melt flow of 4 grams per 10 minutes.
Shuman claims they are easy to process and resist chemicals.
Pelletron plugs small, economical cleaner
Pelletron Corp. discussed its new CCD-DeDusting system for high dust loads and regrinds. The compact and economical system has very high cleaning efficiency, said Pelletron. Regrinds with dust loads of 20 percent or more will be cleaned to dust loads below 1 percent, according to the Lancaster, Pa., company.
System boasts less operator involvement
Toshiba Machine Corp. showcased a new injection molding machine monitoring system it claimed gives better repeatability with less operator involvement. Developed in conjunction with RJG Inc., Toshiba's EC45NII all-electric injection press molded electrical connectors at Plast-Ex.
It uses RJG's eDart system, which monitors the molding process from two cavity pressure sensors behind each injection pin and then displays data on a user-friendly monitor.
Toshiba of Elk Grove Village, Ill., said molders can quickly determine quality and resolve problems.
Hosokawa introduces dedusting machine
Hosokawa Polymer Systems of Berlin, Conn., made a debut of a deduster and fines separator system.
The new KS series machine can process 50-10,000 pounds of material per hour. The deduster can clean a variety of materials, including high density polyethylene, low density polyethylene, PET, polycarbonate, PVC and high-impact polystyrene, for post-consumer recycling, as well as for blow molding, injection molding and extrusion.
The 4,000-pound-per-hour machine on display removed paper out of PET regrind, and copper out of polypropylene regrind.
RJG displays cheaper containment system
RJG Inc. unveiled its eDart flx system for automated part containment. Designed to be more economical than the Traverse City, Mich.'s eDart system, the new version has many of the same features, such as automatic sensor recognition, auto-zeroing of cavity pressure sensors and robust hook-ups. It can detect problems such as short shots or flash before the mold opens so part segregation and containment can be done.
Robot removes parts from presses quickly
Wittmann Inc. introduced a new servo robot for fast part removal from injection presses with up to 300 tons of clamping force.
The W721 UHS robot has a payload of 22 pounds and complex gripper functions. Depending on payload, times for in and out motions are between 0.3 and 0.5 second. The machine is engineered for long life, reliability and stiffness along the moving axes.
Like other Wittmann robots, its features include a space-saving control cabinet and optional packages to upgrade the number of vacuums, gripper circuits and rotational axes. The company has U.S. headquarters in Torrington, Conn.
Chennuo announces plans for new plant
China Chennuo Plastic & Mould Co. Ltd. of Taizhou said it will open a 106,600-square-foot injection molding plant for consumer products by the end of this year.
Chennuo said the new plant will open with 20 employees.
The firm has been focused on exports of molds since it was established in 2004. Company manager Pan Anping said sales double every year and he expects the trend to hold true for 2007.
