    Porous mold needs no venting system

    International Mold Steel Inc. of Erlanger, Ky., has unveiled its new Porcerax porous steel that vents trapped gas from plastic injection molds.

    Gas bubbles through the steel, while resin is contained in the mold, eliminating the need for complex venting systems. A small piece, or several pieces, of the steel, strategically placed in the mold, can vent gas. The steel comes in flat plates and bars.

    The firm said its new pre-hardened steel, DH2F, cuts fabrication costs for die and mold makers. It claims the steel machines 30 percent faster than other H-13 steels.

    New Osco nozzle for large-part molding

    Osco Inc., which makes runnerless injection molding systems, has introduced a new valve gate nozzle for large-part molding.

    The valve gate nozzle system is called the DSCV-500. Osco said the product can be used under a manifold or as a stand-alone, single gate system.

    Patented design features include gate diameters as large as 0.56 inch, a one-to-one drive between the valve pin and cylinder piston and a hydraulic cylinder outside the mold.

    Osco is in Rochester Hills, Mich.

    Toman Corp. offers manual film feeder

    For use in ultrasonic welding, the FilmFeeder from Toman Tool Corp. of Viroqua, Wis., puts a buffer of film between the ultrasonic horn and the part, so any burning is transmitted to the film rather than the part.

    Toman said the new manual model is priced much lower than the automatic version.

    RTP's PC compounds used for thin walls

    RTP Co. has developed a family of polycarbonate compounds to replace liquid crystal polymers or polyphenylene sulfide in thin-wall-molding applications.

    The compounds are suitable for molding strong and lightweight telecommunications equipment, computer components and other devices, said the Winona, Minn.-based specialty compounder.

    The new RTP 300B series offers physical, conductive and flame-retardant characteristics similar to standard PC and can carry precoloring and other attributes.

    RTP will commercialize the compounds in late August.

    Erema develops dryer for reprocessed PET

    Erema, a recycling equipment manufacturer based in Linz, Austria, has unveiled an in-line drying system, the RGA 100 VSV-TE, that uses a cutter compactor vacuum system for processing PET.

    Without pre-crystallization and pre-drying, the free-flowing material is conveyed directly to the cutter compactor. The cutter compactor mixes, heats up, crystallizes and dries the PET in one step.

    Erema claims the system cuts viscosity loss as much as 70 percent and spinning oils 80 percent, making the raw material suitable for processing to polyester fibers and back into bottles.

    The firm's U.S. arm, Erema North America Inc., is in Topsfield, Mass.

    Ross 430-X produces submicron emulsions

    A new X-Series mixer emulsifier from Charles Ross & Son Co., the 430-X, produces submicron emulsions by forcing the mix through a matrix of interlocking channels.

    Results include smaller droplet sizes, faster mixing cycles and emulsions with greater stability than other mixers, the Hauppauge, N.Y., company claims.

    Ross also makes turnkey systems, including heat-transfer equipment, controls, pumps and vessels.

    Komo router grips sheet without clamps

    The new VR 508 router from Komo Machine Inc. holds sheet by vacuum to a table measuring 5 feet by 8 feet.

    The vacuum system offers faster setup and full edge contours without mechanically clamping the sheet, said Komo of Sauk Rapids, Minn. The computer numerically controlled router uses two standard spindles. For added capacity, a 508Q model has four machining heads.
