TROISDORF, GERMANY - At K 2001, Reifenhauser GmbH will run a three-layer blown film line and introduce a lower-priced winder on the show floor, and shuttle K show visitors by bus to its nearby factory in Troisdorf.
Reifenhauser (Hall 17, Stand A 21) makes machinery for producing blown and cast film from one to seven layers. A seven-layer line is running in Troisdorf.
The three-layer Filmtec blown film machine scheduled for the Dusseldorf, Germany, show hall processes 770-880 pounds of plastic an hour, at a speed of up to 430 feet a minute.
In thermoforming, a Reifenhauser three-layer coextrusion line will operate at the K show booth of Adolf Illig Maschinenbau GmbH & Co., feeding an Illig former making PET cups.
In addition to the seven-layer line, Reifenhauser's Troisdorf facility also will run a five-layer cast film line, demonstrate the extrusion coating process, make film for heavy-duty bags and do monolayer blown film line.
Reifenhauser also will make winder news at K, showing the new UFA III-E version of its universal winder, the UFA line.
The company has sold about 50 UFA winders since the line was introduced three years ago. The UFA III-E replaces expensive servodrive technology with a less-costly frequency stabilized alternative-current drive system.
Reifenhauser officials outlined new technologies and the company's strategy during a pre-K show news conference June 28.
Reifenhauser will continue to market complete extrusion lines but also plans to emphasize selling single components such as single- and twin-screw extruders, blown film dies, slot dies for extrusion coating, winders and gauge-control systems. The company is already selling dies as a separate profit center - beefing up production by investing in four- and five-axis machining centers in recent years.
In technology news, the company has developed a better way to make seven-layer barrier film. New screw concepts allow the processing of different types of polyethylene, such as low density, linear low density, high density, ionomers, polypropylene and new metallocene resins - with no need for screw change, according to Reifenhauser. Also for barrier materials, the company has developed new screw geometries that give maximum flexibility and plasticizing performance.
Screws and barrels are made from HIP hard metal (hot-isostatic pressing), giving longer life to these wear components.
Reifenhauser also has created a barrier film die, called HDS (horizontal distribution system), claiming it is more accurate and gives a higher rate of output than conventional multilayer dies. The key feature: patented horizontal melt distributors. By separately heating the melt distribution channels and by adding internal heating, the die sets the ideal processing temperature for the resin in each layer.
Also, the separation of the melt flows continues for a relatively long period, preventing any thermal degradation to sensitive raw materials. Wide internal spacing gives an efficient internal air exchange.
The machinery maker's U.S. headquarters, Reifenhauser Inc., is in Ipswich, Mass.
