Engel introduces Marathon, e-motion
Engel is introducing upgraded injection molding components to North America, and Engel Canada Inc. announced the creation of the e-motion.
Engel's Marathon technology includes screws, tips and nonreturn valves that offer increased abrasion and corrosion resistance, a higher working temperature range to 830° F, and a life expectancy more than double that of through-hardened products.
Guelph, Ontario-based Engel said the new products address trends in compounds and additives that can shorten component life. High filler content, corrosive materials and high processing temperatures attack parts made of conventional steels.
Marathon products provide lower adhesion between melt and metal, Engel claims. High plasticizing rate, less required torque and faster color changes are possible, according to the injection press maker.
Meanwhile, Engel Canada Inc. has joined electric and tiebarless injection press technology into a machine it calls e-motion.
The hybrid press combines the advantages of each of the technologies, claims the Guelph press manufacturer. Together, they provide high precision, improved molding economics, greater power efficiency and molding versatility, according to Engel.
Engel has been supplying tiebarless presses for more than a dozen years and now boasts 15,000 of them in operation around the world. The e-motion features the firm's C-frame. Its Flexlink mechanical compensation linkage is mounted behind the stationary platen to help improve parallelism and centricity. Conventional tiebarless frames have the compensation linkage behind the moving platen.
Independent, fast-acting servo drives allow simultaneous operation of all machine functions for fast cycle times and high productivity. A five-point toggle powered by a servo motor and planetary gearbox offer long life and less maintenance compared with a ball screw. The press includes Engel's standard CC100 controller.

Prepregs experience U.S. demand growth
U.S. demand for structural preimpregnated products is growing significantly, according to a business and marketing analysis from BMR Associates of North Plainfield, N.J.
Benjamin Rasmussen, the consulting firm's principal, projected current-year prepreg sales of $700 million and identified the largest suppliers as units of Hexcel Corp., Cytec Industries Inc. and Toray Industries Inc.
The report's forecast of annual growth of 7-10 percent through 2004 could be conservative, he said in a telephone interview.
Rasmussen said he has seen an upbeat attitude, particularly among the 10 lower-tier prepreg suppliers, and a growing trend toward expanded use of toughened epoxy/carbon fiber prepregs that cure at 250° F for sporting goods, automotive and industrial applications. End users also are seeking materials that cure below 250° F.
Another growth niche involves use of composite prepreg tooling in Indianapolis, where most auto-racing teams are doing fabrication work, he said.
BMR Associates charges $2,500 for the multiclient report, providing two bound copies.

Otto Manner patents new nozzle heater
Otto Manner GmbH of Bahlingen, Germany, has patented a new nozzle heater for hot runners.
The patented device is a new heater band with a unique clamping mechanism. A stainless steel shell houses three cams in the casing of the inner heater band. The inside of the shell is contoured to match the cam arrangement. A hook-shaped key is used to twist both parts together against each other. When twisted, the cams rise and tighten, creating tension between the heater band and the nozzle.
Otto Manner said the design keeps the maximum thermal contact of the heater to the nozzle and eliminates any tolerance difference between the nozzle, the outside and inside diameters, and the heater band.

New sprues: Husky adds 250, 500 series
Husky Injection Molding Systems Ltd. designed its new line of hot sprues, called the 250 and 500 series, for prototype molding and single cavity molds.
The sprues use a single-drop nozzle that has the same design of standard nozzles used on multi-cavity molds. The nozzle is secured to the mold base by an adapter, which supports the nozzle during injection.
Hot sprues can be retrofit on molds that have cold sprue bushings, according to Husky of Bolton, Ontario. Husky's Milton, Vt., operations developed the sprues.
