Two Ineos materials made for appliances
Ineos Americas LLC's styrenics division has developed two resins geared to appliance applications such as refrigerator liners.
The Channahon, Ill.-based division said Avantra 2720 and 535K high-impact polystyrenes can be used together to provide strength at low temperatures, chemical resistance and a high-gloss surface. Avantra 2720 is the base resin for large-sheet uses and 535K is suitable for a cap layer.
Ineos claims Avantra 2720 provides improved stiffness, allowing downgauging and cost savings. The 535K HIPS is tough, flexible and stain-resistant in extrusion and injection molding uses.

Graham Engineering upgrades SPM series
Graham Engineering Corp., which makes extrusion blow molding machines in York, Pa., has made a round of major improvements to its SPM series of machines that transfer material directly into a shooting pot for delivery of the parisons.
The new model features a larger-diameter (4½ inches), high-output, grooved extruder with a length-to-diameter ratio of 28-to-1. It can shoot more than 35 ounces (1,000 grams) per second. Graham also offers shot capacities of 42, 70 or 105 ounces (1,200, 2,000 or 3,000 grams), independent of extruder diameter.
A compact Knodler gear motor runs quietly. The extruder has a PSI model CSC-125 continuous screen exchanger, an option that is not available on a reciprocating-screw machine.
The machine's die head and manifold feature eight heads on 9-inch center-to-center spacing with 100-point parison programming, three-point front die adjustment, a hydraulic ram-down prefinish and blow pin adjusters that have Graham's toolless adjustment feature.
For handling and trimming, the machine has a double swinging takeout arm, an 8-inch Graham cooling bed and a Graham 24-by-24, four-platen, triple-index trimmer with leak detection.
Graham Engineering has been making shot-pot machines for two years. According to Graham, advantages of the shooting pot include the elimination of the ball spline and maintenance to the thrust bearing; continuous extrusion for better melt and lower stock temperatures; the ability to add automatic or manual screen changers, since the material does not have to travel through the screen pack during parison delivery; less shear, thanks to positive displacement delivery; and a faster shot speed.
The company also said the parison is much more stable, because as the plastic goes into the shooting pot, it has a chance to relax and loses its memory of the extruder rotation, so the parison remains straight as it exits the die heads.

Inspire resins made for rigid packaging
Dow Chemical Co. has developed two propylene-based polymers for rigid packaging in its family of Inspire resins.
Inspire 117 Performance Polymer provides balanced strength and clarity for blow molding, according to the company. It has improved stiffness and toughness compared with clarified random copolymers, presenting opportunities for downgauging. Its clarity and high-heat deflection temperature make it well-suited for liquid foods such as syrups, fruit juice and other hot-filled products.
Inspire 404 offers clarity and stiffness in thermoforming. Dow claims clarity is similar to that of amorphous PET and general-purpose polystyrene/styrene-butadiene copolymer. The resin's higher stiffness over conventional PP allows downgauging. It is applicable to drink cups, deli containers and other disposable packaging.

Milacron makes sale to firm in Venezuela
Milacron Inc. has sold a Uniloy Milacron structural foam molding machine to Venezuelan pallet maker Industrias Uniplasticas CA.
Uniplasticas bought the machine at NPE 2006. Milacron said the wide-platen press, with 750 tons of clamping force, is scheduled for a February delivery.
The press will quadruple pallet output over older presses, Milacron said. The wide platen, which measures 167 inches wide by 86 inches tall, allows the machine to run two molds side by side. The machine has 137 inches between the tie bars. It features independent nozzle control and a hot-runner and manifold system.
The machine can run 2,400 pounds of plastic an hour, using a 200-pound shot capacity. Uniplasticas will cut cycle times to 2½ minutes, from six minutes on the older machines, thanks to improved mold technology.
``This machine should produce four times more than one of their existing machines,'' said Ed Hunerberg, executive director of the Uniloy Milacron structural foam machinery business. ``It's good for 250,000 pallets per year.''
Uniplasticas, based in Guatire, Venezuela, is a major producer of plastic pallets, boxes, baskets, construction forms and flooring for the poultry and agriculture industries. The company, which claims to be the largest supplier of industrial pallets in Venezuela and Colombia, also exports to Ecuador, Peru and Costa Rica.
Pallet sales have doubled each year for the past several years, according to Frank Adam Mendoza, commercial manager. They are sold under the Uniplast name.
Milacron's structural foam machine business is in Tecumseh, Mich.

Kuka Robotics offers KR5 Sixx
Kuka Robotics Corp. said its KR5 Sixx family of robots gives six-axis technology to tasks that require a long reach - applications such as pick-and-place, assembly or materials handling.
KR5 Sixx robots include models that reach 26 inches and 34 inches and can handle as much as 11 pounds. The light weight of the robot means it moves quickly.
Kuka Robotics is based in Clinton Township, Mich., near Mount Clemens.

ReifenhÃ¤user shifts corporate structure
ReifenhÃ¤user GmbH & Co. KG Maschinenfabrik, a German maker of blown and cast film machinery, adopted a new corporate structure July 1, when the activities of all film equipment divisions were pooled into the newly established ReifenhÃ¤user Extrusion GmbH & Co. KG.
ReifenhÃ¤user Extrusion now includes the blown film, thermoformed sheet, chill roll/laminating and component product areas, plus customer service and central production.
Klaus and Ulrich ReifenhÃ¤user, who head ReifenhÃ¤user Maschinenfabrik, will lead the complete group of companies, which includes ReifenhÃ¤user Extrusion, ReifenhÃ¤user Reicofil, Reiloy, Reimotec, Polyrema and ReifenhÃ¤user Machinery China.
In other news, ReifenhÃ¤user:
* Presented a cast film line at an open house in Troisdorf, Germany, that can process film in one to seven layers. Four of the seven extruders are from the direct-drive REItorque series, with a smaller footprint and lower energy consumption than conventional extruders. Other features include an intelligent heating-up program and special screws that boost throughput while maintaining homogeneity.
* Showed a three-layer Filmtec 3-1700-IBC blown film line, with output 25-30 percent higher than other film lines. The REItorque extruder is outfitted with a newly developed low-temperature screw.
The firm's U.S. unit, Reifenhauser Inc., is in Ipswich, Mass.
