Univeral Dynamics offering grinder line
Universal Dynamics Inc. used Plastics Encounter Southeast to roll out its first grinders - a low-priced line called AutoGrind, made in China.
``We now offer a full line of beside-the-press granulators,'' said Tom Martin of the Woodbridge, Va.-based auxiliary equipment supplier. Martin is product manager of the Autoload business.
Universal Dynamics claims the grinders are priced 70-80 percent below competing grinders. Prices start at $3,300 for low-speed grinders, $4,500 for screenless grinders and $6,500 for general-purpose models.
Company officials would not identify AutoGrind's maker. Universal Dynamics is the sole U.S. distributor.
Five years ago, Universal Dynamics bought Autoload, which makes injection press hoppers that act as small materials-handling systems. Martin said Autoload still runs as an independent company within Universal Dynamics. The company decided to put AutoGrind grinders into the Autoload operation.
Available in eight models, the screenless grinders have a see-through, polycarbonate hopper. The units come with cutting chambers of 4 by 6 inches to 17 by 10 inches.
Cutting chambers on the low-speed granulators range from 51/2 by 6 inches to 161/2 by 8 inches. Universal Dynamics offers them in 13 models.
The 10 models of general-purpose grinders range in size from 9 by 91/2 inches to 14 by 36 inches. The machines have an integral, soundproofed blower and cyclone as standard features.
Universal Dynamics expects to add larger AutoGrind models. The firm will handle service and spare parts.
June molding classes
Plastics worker certification, an idea that has waxed and waned in recent years, is back, as Paulson Training Programs Inc. launches its School of Molding in June.
Each of three levels of certification comes after a weeklong, intensive molding course. Students work with computer simulation and run an injection press.
The first course will be held at MGS Manufacturing Group in Germantown, Wis.
Attendees will be placed in the appropriate-level class, based on molding knowledge and experience. Paulson will use its online molding test, SkillCheck, to assess students' strengths and weaknesses.
Tuition ranges from $1,195-$1,995, depending on the level. Class sizes are limited.
Synventive Molding Solutions is promising to ship its new Kona XP hot-runner systems in four weeks - even for custom-made configurations.
Peabody, Mass.-based Synventive said the guarantee covers virtually every Kona XP system, from straight-bar systems to complex, multileg systems for automotive parts and sequential valve-gate systems.
The promise does not cover stack molds and systems with mold plates, which ship in six weeks.
Two Specialty units
Indianapolis-based Specialty Manufacturers Inc. has purchased a 7-ton Nissei press for molding medical products at its Apollo Plastics Division in Chicago.
The firm also added a high-speed milling machine for making molds at another division, D&M Tool Corp. in Springville, Ind., said David Lucas, sales manager at Specialty Manufacturers. He said the Roeders RP 800 milling machine reduces the need for mold polishing.
Also, the firm transferred a 200-ton JSW press from Apollo to its PRD Inc. division in Springville.
Wittmann adds shaft
to SJD granulators
Wittmann Inc. has added an optional third shaft with breaker knives to its SJD series of low-speed, beside-the-press granulators, improving the machines' ability to grind bulky parts such as automotive bumpers.
The optional shaft allows parts to be fed into the smaller hopper by reducing their size before they reach the cutting chamber. The shaft uses four standard breaker knives, which are keyed and offset for more-efficient cutting. The hardened, high-alloyed steel combs and counter combs can be reversed to double their life.
In robot news, Wittmann showed a dual pendant control. The robot can be operated from nearly anywhere in the work cell, without the limitation of a fixed, machine-mounted control station or a single limited-reach pendant.
Wittmann also introduced a modified version of its top-entry servo robots designed for clean room operation. The design is available on several models.
The machines conform to Class 1,000 or above, according to the company in Torrington, Conn.
Wittmann also introduced a line of portable chillers called CoolPro, from 1-20 tons. Both water- and air-cooled models offer digital temperature control. Standard features include Copeland scroll compressors, stainless and galvanized steel internal shelving and brackets and powder-coated steel exterior cabinets.
DTR touts software's
DTR Software International introduced Version 9.2 of its Manufacturing Manager, a planning system for plastics processors.
TMM v. 9.2 delivers inventory management, information analysis and operational efficiencies. Plus it speaks several languages. DTR of Jacksonville, Fla., introduced the Language Localizer function. Users can translate labels, messages, menus and other text elements.
DTR said that, while the number of languages a company can choose is virtually limitless, each user can select as many as three languages in which to work. That means people working side-by-side can view the same screen in a different language.
In people news, DTR named Kelly Turner marketing manager.
MTI PP pellets have
4 rovings per strand
MTI Thermoplastic Composites, which makes long-fiber-reinforced compounds in Matthews, N.C., introduced a long-glass polypropylene with four rovings per strand instead of just one - boosting the bulk density and giving better impact strength from molded parts.
The pellets are a half-inch long. Each pellet contains a quarter-mile of total fiber, said President Larry Montsinger. With four rovings, MTI increased the bulk density by 25 percent and reduced the pellet aspect ratio 50 percent.
The pellets feed better, and retain more of the fiber length during processing, according to MTI.
Screen-changer maker PSI-Polymer Systems Inc. said its new segmented ring seal eliminates material hang-ups and tightly seals the screen changer, eliminating leaks.
The patented design uses segmented, all-steel parts, with no Teflon. Other sealing rings made of Teflon work by expanding under heat and pressure from the polymer melt.
With the PSI device, pressure-activated segments of the ring move out a tiny amount, to seal against the housing.
The seals were introduced on PSI's hydraulic screen changers. Bart Jones, who designed the seals at Hickory, N.C.-based PSI, said the company has incorporated the segmented taper-ring seals into its line of manual screen changers. PSI offers a lifetime guarantee on all seal parts at processing temperatures between 70Ã¸ F and 700Ã¸ F.
Incoe names Bauer
an Asahi sales rep
Incoe Corp. announced that it has appointed Bauer Plastics Technology Group to handle North American sales for the External Gas Molding technology from Asahi Kasei Corp.
Incoe of Troy, Mich., is a licensed Asahi Kasei distributor. The alliance with Bauer allows Incoe to concentrate on its core business of hot-runner technology. Bauer, a supplier of gas-assisted molding technology, increases its product offerings in North America.
Also, the companies said the license has been simplified by reducing the mold fee to a one-time payment of $5,000.
Bauer is based in Clinton Township, Mich., near Detroit.
