Coinjection machines touted for flexibility
A new line of Magna coinjection molding machines from Cincinnati Milacron Inc. brings hot-runner technology to the coinjection molding process.
Magna machines have capabilities for multicavity, hot-runner coinjection; multigated, hot-runner coinjection with a single cavity; and multicomponent, two-color coinjection overmolding.
Milacron's Batavia, Ohio-based Plastics Technologies Group said Magna machines can combine core and skin materials with two radically different sets of properties.
They can mold applications such as high-gloss or colored automotive interior parts that have cores of low-cost regrind, soft-touch handles, steering wheels with engineering-grade cores, engine parts with chemically resistant skins and electronics housings with a core of material to shield from electromagnetic interference.
Milacron engineers developed an isolation manifold that allows independent and simultaneous operation of each injection unit.
Magna machines come in clamping forces of 500-4,000 tons.

Arizona will exhibit moisture analyzer
Arizona Instrument Corp. will show a new moisture analyzer for plastics, the Computrac 3000, at Plastics Fair Cleveland, June 23-25.
The easy-to-operate device has a range of 10 parts per million to 1 percent moisture, and a detection limit of 10 micrograms of water. Test results are available in as few as three minutes. The unit automatically stops the test when it collects enough information to determine moisture content accurately.
Computrac is designed for use either on the laboratory or production floor. Arizona Instrument is based in Phoenix.

Oxygen mask housing wins ICE expo award
A housing for emergency oxygen systems on commercial airplanes netted a composites design award for Zehrco Plastics Inc. of Ashtabula, Ohio.
The firm won the aircraft/aerospace/defense award at the International Composites Expo '98, held Jan. 19-21 in Nashville.
Zehrco compression molds the housing, which must meet regulations for low smoke and low flame. The housing holds oxygen containers and the masks that drop down in front of airline passengers.
The thinnest part of the housing is 0.035-inch, which is molded without sacrificing part strength, Zehrco said.

Flame retardants not toxic, irritating
Eastern Color & Chemical Co. has introduced three flame retardants that it claims are suited to a range of polymers and are nontoxic and nonirritating.
Eccogard A-5 is a liquid targeted for nylon, polyolefins and urethane foams. The Providence, R.I., company said typical usage levels of the product, based on a chlorinated-phosphonate polymer, range from one-half percent to 10 percent.
Eccogard A-10 Base, a liquid organo-phosphate polymer, is suited to nylon, polyolefin fibers, molded components and urethane foams. Typical loadings range from one-half percent to 10 percent.
Eccogard A-12 is a powdered amino-phosphate for nylon, polyolefins, polyesters, styrenics and urethanes. Usage levels range from 15-45 percent.

Flax could replace glass in composites
Flax fibers, now burned as a waste product by Canadian farmers, could be the next reinforcement for composites, according to Isorca Inc. and Cargill Ltd.
Isorca is touting molded parts with 30 percent polypropylene and 70 percent flax fibers. Polyester also can be used.
Cargill, a major Canadian agricultural commodities processor, has established a joint venture with farmers in Canora, Saskatchewan, the center of a major flax-growing area. Flax seed is valuable for its oil seed, used in oil-based paints, linoleum and other products.
Canadian farmers burn 1.5 million acres of flax straw a year, said Francis Kolla, Cargill's flax fiber marketing director. The joint venture in Canora, called Durafibre Inc., offers several grades of fibers.
Cargill hired Isorca, a Granville, Ohio, research and development firm, to generate composites markets for flax. Flax fibers cost one-half the price of glass fibers.
Isorca also announced that Applied Sciences Inc. of Centerville, Ohio, has developed technology to make vapor-grown carbon fiber from coal and natural gas. Isorca also is helping American Electric Power to commercialize a filler made of fly ash, a waste from coal-fired electricity plants.
