Plastics News senior reporter Bill Bregar picked up the following news from the show floor at Plastics Encounter, held June 22-24 in Cleveland.
Moditec granulator handles biggest jobs
Janet Kevlin tossed an inch-thick, glass-reinforced black nylon part into the Goliath G3 S ACP granulator from Moditec srl - a beside-the-press granulator with a 3-horsepower motor.
That's one big chunk of plastic for such a small, low-speed grinder. Thanks to the clear polycarbonate hopper, show visitors could see the plastic being ground up.
``It's slow-speed, high-torque. All other manufacturers run basically purged sprues and runners with slow-speed grinders,'' said Kevlin, national sales manager for Plastec North America Inc. in Miami.
The beside-the-press granulator can handle bad parts, or several sprues and runners tossed in all at once. Kevlin said those applications can cause a small granulator to seize up.
The single-shaft G3 S ACP granulator, with a cutting chamber measuring 9 inches by 14 inches, gives the benefits of low-speed grinding - fewer fines and longs, with practically no dust. It also runs quietly.
Moditec of Marennes, France, also makes twin-shaft granulators that can handle large parts from automotive and other markets.
Plastec North America exhibited in the booth of its representative in Ohio and western Pennsylvania, Kempco & Associates Plastic Equipment Inc. of North Royalton, Ohio.
Plastic recycler buys Canterbury 22-footer
Canterbury Engineering Co. Inc. sold a 22-foot-long screw with a 6-inch diameter in a deal inked at the show, according to John Greer, sales engineer for the screw and barrel maker from Chamblee, Ga.
The screw will go to a company that recycles plastic and pelletizes the material, though Canterbury would not identify the customer.
The screw has the same dimensions as the whopper that Canterbury Engineering was displaying at the show, with a length-to-diameter ratio of 32:1. The displayed screw was for sheet extrusion.
Greer said his company had quoted the screw. An official from the customer visited the show and sent the purchase order to Canterbury headquarters June 24.
Greer said Canterbury Engineering is exhibiting at more trade shows as the company promotes its capabilities.
Canterbury makes screws, barrels and other components for extrusion, and injection molding screws.
Certification course aimed at toolmakers
RJG Inc. launched a certification program for mold makers, at the mold-shop level.
The firm in Traverse City, Mich., already conducts training for mold makers.
``The idea is, we take the training to the mold builder,'' said Rebecca Hamstra, account manager for sensors.
The cornerstone of the course is using real-time data from within the mold, such as cavity pressure, flow rates, temperatures, mold deflection and cooling rates.
That understanding of the plastic during molding is related to part design, mold design and manufacturing, and how to challenge the mold during a tryout so it will run its best during production.
Criteria include a minimum of one RJG sensor tester and completion of an RJG in-plant training series.
Hamstra said RJG will promote its certified mold-building facilities on its Web site, with a link to the mold company's Web site.
``We want to be able to foster better communication between mold makers and the molding community,'' Hamstra said.
For mold shops that run mold trials on presses, RJG announced certification of tryout facilities.
Attendees hit 2,400 for collocated shows
Plastics Encounter Midwest and MoldMaking Expo 2004 drew about 2,400 attendees and 819 exhibitor personnel.
The count includes attendance for AmCon, the American Contract Manufacturers show, which ran during the same time at the Cleveland I-X Center.
The Plastics Encounter show, presented by Plastics News, had 541 exhibitors. MoldMaking Technology magazine sponsored the MoldMaking Expo, which had 277 exhibitors.
