Plastics News correspondent Michael Lauzon reported the following stories from the Plast-Ex 98 show held in Mississauga, Ontario, May 12-14.
Toshiba's new press molds precise parts
Toshiba Machine Co. unveiled its new 30-ton injection molding press for molders of precise, small parts.
The ISFA30 has tie-bar spacing of 10.2 by 10.2 inches and platen dimensions of 15 by 15 inches. The firm offers injection units with shot capacities from 0.5-2.3 ounces.
Toshiba also said it added a 1,150-ton press to its lineup. The ISGT1150 has tie-bar spacing of 49 by 49 inches and a 68.3-by-68.3-inch platen. Clamp stroke is 69 inches and ejector force is 27 tons. Toshiba also said the machine's small footprint saves about 30 percent on floor space.
Bekum sells latest blow molding unit
Bekum America Corp. sold one of its newest large-platen blow molding machines to an undisclosed company, an official said at the show.
Bekum ran the BM-704S machine at Plast-Ex to highlight features of the single-sided, continuous extrusion blow molder. It has 22.4 tons of clamp force and is capable of two-cavity production of containers as large as 2.6 gallons. The machine includes three-stage automation with water-cooled transfer pins.
Kona's system aids access to hot runners
Kona Dynisco's hot-runner group recently introduced the Quick Couple Valve Gate, an actuator system to make hot runners easier to access and service and to reduce plumbing.
The system features a coupling attached to the cylinder by a snap ring. An operator can access the manifold by removing the snap ring and lifting the clamp plate. The coupling allows free movement for manifold thermal expansion to prevent alignment problems.
Nova adds film line, taps spinoff's execs
Nova Chemicals Ltd. recently added a three-layer blown film line for lab work, and introduced new grades of polyethylene to the compounding and masterbatch market.
Nova is using the Brampton blown film line at its Calgary, Alberta, technical center to test coextrusion resins and runs as many as eight material blends a day on the equipment.
Nova estimates that coextrusions make up about 30 percent of North America's film market.
Of Nova's new compounds, GM-1224-A is a linear low density PE with a melt index of 12 that bridges the gap between low- and high-melt-index resins. This property helps processors get midrange melt viscosities without blending PE resins. LM-1019-A is a conventional LDPE with a 10 melt index.
Meanwhile, Nova has tapped the senior managers who will lead the company when it becomes a separate, publicly traded concern this year.
Jeffrey Lipton will become president and chief executive. Daniel Boivin will be president of the olefins and polyolefins unit; Dale Spiess was named senior vice president of polyethylene sales and marketing. In styrenics, Wes Lucas will be senior vice president and general manager.
Other executives include A. Terence Poole, executive vice president of finance and strategy, and Wayne Lunt, senior vice president and chief financial officer.
Teknor Toronto office appoints sales reps
Teknor Color Co. appointed Frank Persaud as sales representative for its recently opened Toronto sales office. Persaud formerly was senior account executive for polypropylene and polyethylene in eastern Canada for Millennium Petrochemicals Inc.
Parent Teknor Apex Co. said it, too, will boost its presence in Canada by opening a sales office dedicated to Canadian sales. The compounder plans to open the office by summer in the Buffalo, N.Y., area. Jon Mello was appointed sales representative responsible for PVC and thermoplastic elastomers in the new office.
Polytech introduces first line of extruders
Polytech Machinery Ltd. showed its own line of extruders for the first time.
Polytech President and owner Guy Smith said his firm has been building extruders for about three years but selling them ``by word of mouth.'' It started the program when the used-equipment market sagged and Polytech wanted work to fill its Brampton, Ontario, shop time.
Polytech extruders, based on a rugged gearbox design, are priced competitively for film, profile, sheet and pipe markets, he said.
Polytech also will continue in the machinery rebuilding market.
Shuman introduces scented compound
Shuman Plastics Inc. unveiled a scented product in its line of Dyna-Purge purging compounds.
The product has a citruslike scent that neutralizes odors associated with injection press purging. It is available in several grades for different purging temperatures and materials. Shuman also will introduce a scented purging compound for extrusion later this year.
Horn Group offers training software
The Horn Group, a Whitby, Ontario, custom injection molder and mold builder, introduced generic training software for injection molding.
InjePro includes 30 hours of narration, text, video clips and self-evaluation exercises, and is contained on four CD-ROM discs.
Horn claims the training tool is cost-effective compared with in-house and outside seminars.
AEC's chiling station makes debut at show
AEC Inc. introduced its Pinnacle series central chilling station.
The chiller features independent refrigeration circuits with scroll compressors, oversized pumps and an integral stainless-steel tank. AEC claims Pinnacle models have the smallest footprint of such chillers and refrigeration capacity from 30-90 tons.
M.A. Hanna targets Canadian molders
M.A. Hanna Resin Distribution opened a Canadian sales office in Toronto in mid-May.
The operation will focus on injection molders, said account manager W. Andrew Spicer. It will offer molders more than 3,000 thermoplastic grades and technical support, including services at Hanna's Atlanta design center.
David Ellis is general manager of the Toronto operation.
