Pipe-cooling system reduces cost, space
KraussMaffei Berstorff's new technology for internal pipe cooling reduces the initial cost and space requirements for a new pipe extrusion line, and boosts the productivity of existing pipe lines.
The system uses ambient air, sucked through the center of the pipe at high speed against the haul-off direction using a side channel compressor. IPC used together with conventional external water cooling in vacuum tanks and cooling baths cools the moving pipe gently from the inside.
The company said the technology can cut the required length of the cooling zone by as much as 40 percent. Or, keeping the cooling the same length as a traditional line, an IPC system can increase productivity by up to 60 percent over a conventional production line.
Munich-based KraussMaffei Group's U.S. operation, Krauss-Maffei Corp., is in Florence, Ky.

M&H produces tubes with photo-like images
U.K.-based packaging maker M&H Plastics Ltd. has developed a new print technology to print photo-realistic images directly onto tubes, eliminating the need for a label.
M&H has machinery that can manufacture and decorate up to a million tubes a week. Tubes are available in any color, white or transparent.
The company, which also runs a plant in Winchester, Va., offers a full range of other decorating technologies, including flexographic and silk-screen printing, labeling and hot-foil blocking. M&H also supplies screw caps and snap-on dispensing closures for the tubes.

Nozzle tips cut flow to prevent drooling
DME Molding Supplies, the maintenance, repair and operations division of mold component maker DME Co., has introduced Mini-Shut automatic nozzle tips.
Mini-Shut cuts off the flow of plastic into a mold to prevent drooling and stringing without requiring mold decompression.
The Mini-Shut fits a niche in the market as a low-cost way of stabilizing the injection process and eliminating many surface imperfections on parts, said Jim Hunt, manager of DME Molding Supplies. Competitive products cost several-thousand dollars. Mini-Shut is only a fraction of that.
DME is based in Madison Heights, Mich.

Plastic Technologies offers app for resin IV
You've heard of Angry Birds? Well, Plastic Technologies Inc. has its own free iPhone/iPad app for your inner geek: It calculates the final intrinsic viscosity for PET resin.
Holland, Ohio-based PTI said the application is the first of its kind for the plastics packaging industry.
Intrinsic viscosity, or IV, has a major impact on how PET resin will be processed. After resin arrives at a processor's factory, it typically gets dried to remove as much moisture as possible before being used to create preforms and bottles. The resin manufacturer has indicated what the ideal processing IV should be, but since PET resin absorbs moisture, it has to be dried before processing.
Without knowing the actual IV, you run the risk of creating packaging that doesn't meet performance specifications, said Scott Steele, Plastic Technologies' vice president of global analytical labs, training and enterprise projects.

Boston Matthews line produces PE tubes
Boston Matthews Inc. has launched a new range of medium-speed squeeze tube extrusion lines, for making thin-walled polyethylene tubes for packaging. The lines can make tubes in one through five layers.
Boston Matthews showed the medium-speed line at the K 2010 show last fall in Germany.
The die head gives the ability to change color or polymers faster, producing different tube-layer configurations without adjustment and with simple disassembly on the extrusion line and shorter flow passages for higher-quality production, according to Boston Matthews.
Boston Matthews is based in Norwood, N.J.

Refurbishing service extends life of dies
Davis-Standard LLC's new die-refurbishing service can extend the life of monolayer and coextrusion foam dies.
Over time, residue can build up in the die channels, affecting the quality of the foam sheet. Davis-Standard said channel coatings often need replacement, and die lips can become damaged.
Refurbishing services can be an effective alternative to purchasing a new die and can be completed with minimum downtime, said Doug Comeau, Davis-Standard's product manager of foam.
Davis-Standard is based in Pawcatuck, Conn.

Frigel introduces water-cooled chillers
Frigel North America Inc. of East Dundee, Ill., has introduced the Microgel RCP line of self-contained, water-cooled chillers.
The 12 new models, ranging in size from 9.2-126.7 tons, are single-zone units designed for a variety of markets, including PET, closure molds, multicavity molding, high-speed medical molding, blow molding and other applications that need refrigerated, high-pressure/flow coolant.
Microgel RCPs are equipped with shell-and-tube condensers to function with a Frigel Ecodry closed-loop water-cooling system or a conventional evaporative cooling-tower system, with or without a heat exchanger. When used with a closed-loop system, Frigel offers the four largest CRP units with a free cooling option.
