    Dynisco introduces pressure transducer Dynisco Inc. is marketing a new premium series of pressure transducers, and a tip heater for hot-runner systems that independently controls the temperature of the plastic in the tip.

    Dynisco HotRunners said processors can change the temperature in each gate without hurting the rest of the process, which allows a wider processing window and faster mold starts, according to the company in Gloucester, Mass.

    The tip heater also helps avoid blush, a problem when gating opposite a cosmetic surface. Dynisco said blush typically is caused by cold material that hangs up in the gate area. When it is forced through the orifice, it shears. The heater lets the material flow more easily.

    Dynisco is based in Sharon, Mass. The company also has introduced the DLX series of premium transducers for extrusion. A special titanium nitride coating on the threads protects against damage caused by galling.

    For injection molding, a new series of cavity-pressure transducers provides direct or indirect measurement using piezoelectric transducers.

    Dynisco also is selling Dynipak, pre-packaged product kits that contain a transducer, connector cable, anti-seize compound and other items a processor can use to start extrusion control quickly.

    Tria machine grinds film-cutting scrap

    An Italian company, Tria di Anceschi e figli srl, has invented a machine that grinds the trimmings produced from cutting reels of plastic film.

    The company said the machine can grind trimmings from six film-cutting lines, with six independent grinders. Each unit consists of a fan to suck in the trimmings, a granulator with three rotary knives and a soundproof, centrifugal separator to discharge the ground material into a large collection bag.

    Dust is conveyed into a centralized filter fitted with an automatic cleaning device.

    Tria of Milan said the machine can grind 1,100 pounds of trim scrap an hour.

    Blow molded parts produced sans flash

    Meico srl of Milan, Italy, has developed a blow molding machine that makes three-dimensional parts with no flash. The machine also can produce sequential or coextruded parts, using a novel conveyor arrangement.

    The machine, called T12/S3D, can use existing molds. Meico developed the press in conjunction with a German blow molding company that uses the machine to produce automotive air ducts.

    The platens are arranged horizontally. Twin 60-millimeter extruders, each with its own accumulator head, deliver melt to a single coextrusion head.

    The machine extrudes the parison onto a heat-resistant conveyor, which is driven in the same direction and at the same speed as the extruded material. The emerging end of the parison is nipped by a pair of welding cutters. A pre-blow process is applied before the parison is nipped to length.

    Meico said that sealing both ends helps the parison maintain stability.

    The parison is pre-shaped right on the conveyor, before it goes into the molds. At the same time, a pair of formers are driven in from each side, holding the parison, while the conveyor is drawn away and the lower moving platen begins to rise. The formers are withdrawn and the shaped parison drops into the mold.

    Meico said the shaping and mold-loading process takes only a few seconds.

    The Italian company claims the process is simpler and cheaper than German and Japanese technology to create technical parts.

    PTI unveils details of 2 Trident systems

    Processing Technologies Inc.'s new Trident extrusion coating system positions the extruder and a flat die in relation to a stationary die stand. In traditional systems, crews have to move the die stand, and the extruder is fixed in place.

    PTI of St. Charles, Ill., said the Trident system is easy to reconfigure.

    The extruder and coating die are positioned at a right angle to the roll stand. A motorized carriage moves the extruder up and down, and backward and forward.

    The entire machine is mounted on rails. The coating die is cantilevered off a support built into the base of the extruder.

    PTI said the movable extrusion coating system permits in-line adjustments of the distance between the die lip and the roll surface. That benefit allows a processor to alter the coating thickness and allow thinner or thicker webs to pass through the coating area.

    The extruder also can be positioned at different locations on the line, depending on the desired application and coating location.

    Also new from PTI is the Trident J-Stack sheet-takeoff system, which yields 25 percent greater utilization of roll cooling than vertical configurations, the company claims.

    The J-Stack has a 45-degree approach, which helps when processing low-melt-strength materials by allowing the extrudate from the die to enter the primary roll nip point at closer proximity than with a vertical system.

    Cumberland presents press-side granulator

    Cumberland Engineering LLC will use single-shaft rotary grinders from ReTech Industries Inc. of High Point, N.C., under Cumberland's private label.

    The ReTech rotary grinders, designed to handle large, bulky parts, work together with Cumberland granulators to provide a two-pass system.

    South Attleboro, Mass.-based Cumberland also has introduced a new beside-the-press granulator, the Auto 700LS series.

    Standard features include an oversized bin with a nominal surge capacity of more than 1 cubic foot and dual-level sensors; a newly designed cutting chamber with a multiple-knife, helical rotor; and a newly designed base for easy access by operators and service technicians.

    Cumberland is owned by Harbour Group, a St. Louis-based company that also owns auxiliary equipment manufacturer AEC Inc. of Wood Dale, Ill.
