NDC Infrared debuts its rotary scanners
NDC Infrared Engineering has developed a family of rotary scanners for blown film.
The scanners can do a complete scan per minute of the film bubble, depending on bubble diameter. NDC said its equipment significantly improves the feedback time for the gauging system to generate a polar plot of the bubble profile.
The Irwindale, Calif., firm offers scanners for blown film bubbles up to nearly 9 feet in diameter.
Without the rotary scanner, the gauging system must wait for the oscillating die or haul-off to complete rotation before it gives an update. That can take several minutes, NDC said.
NDC said the rotary scanner is installed below the collapsers and above the frost line of the blown film system. The gauging system includes NDC's telescopic probe positioner to keep the sensor in the proper position to the bubble at all times.

Zeon TPV elastomers temperature-resistant
Zeon Chemicals LP has added a temperature-resistant, blow moldable thermoplastic vulcanizate to its Zeotherm TPV elastomers product line.
Zeotherm 120-90B can withstand temperatures ranging from minus 104° F to 347° F while retaining softness and flexibility, according to the Louisville, Ky., company. The new elastomer is well-suited for automotive boots, bellows, ducts and similar uses.
Zeon claims the new material allows auto firms to eliminate heat shields that can be specified to protect elastomeric boots and similar products. Zeotherm 120-90B is a cost-effective alternative to silicone and ethylene acrylic rubber boots when temperature demands reach 284° F and higher. High resistance to grease also qualifies the product for demanding vehicle applications.

Engel to introduce press for packaging
Engel Speed - a new line of injection presses for high-speed packaging from Engel Holding GmbH will be unveiled at the Fakuma trade show, set for Oct. 18-22 in Friedrichshafen, Germany.
Engel announced last year it was moving back into the market for high-speed presses to mold thin-wall packaging.
The Schwertberg, Austria-based press maker reduced the moving mass of the injection unit to a minimum, helping the machine read injection speeds up to 1,000 millimeters per second. Instead of using the tie bars to guide the moving platen, that function is handled with a carriage on the Speed. At Fakuma, Engel will mold polypropylene yogurt cups on a six-cavity mold, with a 3½-second cycle time.
In other Engel news, Dutch pipe fittings molder Dyka BV purchased an Engel Victory press with a tie-barless clamping unit. Dyka of Steenwijk, the Netherlands, has bought a total of 60 Engel injection molding machines.
Dyka, part of Tessenderlo Group, does an average of 25 mold changes per day, making tie-barless presses a big attraction, because they allow unrestricted access to the mold area.
Engel's North American operation, Engel Machinery Inc., is in Guelph, Ontario.
