Law prompts need for tiny preform mold
PET Engineering srl of San Vendemiano, Italy, said Husky Injection Molding Systems Ltd. of Bolton, Ontario, has made a prototype preform mold for its single-serving, ``monodose'' PET containers, which PET Engineering will introduce at the Drinktec show in Munich, Germany, in September.
According to PET Engineering, a strict new Italian law will drive demand for the 6-ounce monodose bottles. Beginning July 19, restaurants and pubs no longer will be able to serve a simple glass of sparkling water or other beverages; they will have to use sealed containers.
The goal for the monodose was to create a preform that can run on existing equipment, with smaller preforms to use material more efficiently. PET Engineering worked with Husky and Corvaglia Ltd. of Kaltenbach, Switzerland, which made the bottle-cap molds.
Instead of using existing preforms for half-liter bottles, the companies developed very small preforms that weigh less than one-third of an ounce.
PET Engineering said the law could spread to the entire European Community.

Accumulator head is largest yet for D-S
Davis-Standard LLC has introduced its largest-ever accumulator-head blow molding machine, and the Pawcatuck, Conn., company plans to go even larger, with clamping forces topping 400 tons.
Demand from customers that mold large, outdoor, industrial parts is prompting the move.
``We've seen an increased demand for machines with 50-pound head sizes and larger driving the market,'' said Frank Kennedy, sales director for blow molding machines.
Kennedy said the big new machine has a 75-pound head size and a clear-platen space of 6 feet by 9 feet. It features a low-profile design with three tie bars for maximum accessibility. The end frame has an innovative waffle design to improve rigidity and reduce weight.
Davis-Standard currently builds accumulator heads with shot sizes as large as 125 pounds.

ReifenhÃ¤user targets wood-plastic market
ReifenhÃ¤user GmbH of Troisdorf, Germany, teamed up with Kosche GmbH to show their WPC-Kovalex technology for wood-plastic composites at the Ligna trade show in Hanover, Germany, held in May.
Kosche, based in Much, Germany, developed the extruded wood called Kovalex. Kosche and ReifenhÃ¤user, which supplies its twin-screw Bitruder, are marketing extrusion equipment to the wood-plastic market.
The Bitruder has counter-rotating, intermeshing screws. Screw diameters range from 3-5.3 inches. Output capacity is 264-1,430 pounds per hour.
Wood extrusion is not new for ReifenhÃ¤user. Officials said the company built an extrusion line for wood sheet in the mid-1970s.
The company's U.S. unit, Reifenhauser Inc., is in Ipswich, Mass.

Gloucester provides I/O control system
Battenfeld Gloucester Engineering Co. Inc. has developed a distributed input/output control system that cuts costs by placing the control modules at the parts of the film or sheet extrusion line where they run, instead of having a centralized control cabinet with interconnect cables.
``The system simplifies electrical engineering, cuts machine installation time by about 50 percent, reduces cable installation cost by 75 percent and permits faster testing and trouble-shooting,'' said Tom Nowak, director of new product development.
A 75 percent reduction in cable costs amounts to big money. Nowak said a typical blown film line with six to nine control cabinets can cost a customer $75,000-$200,000 for control cabling alone.
In the distributed I/O system, the separate modules are connected to Battenfeld's proprietary Extrol system, which monitors the data, regulates the modules and controls process parameters. Modules can control functions such as blenders, extruder motors, barrel heaters and dies.
The machinery maker in Gloucester, Mass., developed the distributed I/O system and is installing it on new blown film, cast film and sheet lines. In the future, the company plans to make it available on all equipment. Nowak said distributed I/O probably will not be available as a retrofit.
In other news, Battenfeld Gloucester has sold a three-layer cast polypropylene film line to CBS Elos do Brazil.
Equipped with three Contracool extruders, the line can make film that is 10.2 feet wide. It can process 2,420 pounds an hour. CBS Elos will use the machine for laminating and metalizing PP film.
Jorge Goldschmied, Battenfeld Gloucester's sales director for Latin America, said the sale marks the first CPP line of that size in Brazil, and the second one in Latin America.
The machinery maker is based in Gloucester, Mass.

Recirculating pump aids devolatization
American Leistritz Extruder Corp. has developed a sealed-oil recirculating pump system that helps with devolatization on its compounding extruders.
The oil ring pump replaces once-through, water-sealed vacuum pumps to pull vacuum from the extruder vents. The pump typically runs two to six months before the oil has to be replaced.
The oil-sealed design eliminates the environmental problems of disposing of waste water from the water-sealed pump, according to American Leistritz of Somerville, N.J.

Stanelco promotes packaging method
Southampton, England-based Stanelco plc is marketing its new Greenseal packaging application and has retrofitted a Multivac R240 thermoforming machine and sealer for sale to U.S. grocers and retailers.
Stephanie Morgan-Fisher, director and chief executive officer of North American operations, said the retrofitted machine marks a ``major milestone'' in retail food packaging.
``There are significantly more thermoformers in the marketplace than there are tray-lidding machines,'' she said. ``This is a major advancement for the packaging of bacon, cooked meats and sliced cheeses.''
Founded in 1953, Stanelco develops applications for radio-frequency technology. The firm said it recently signed an exclusive agreement in the United Kingdom and Ireland with ASDA, Britain's food and clothing superstore and a subsidiary of Wal-Mart Stories Inc.
Stanelco recently opened a sales office in Orlando, Fla.
Meanwhile in Europe, Stanelco is working with an Italian maker of tray-lidding equipment, G. Mondini SpA, to develop an RFT lid machine.
