ROSEMONT, ILL. - Battenfeld of America Inc. officials said its German parent is studying whether to begin making a tie-barless injection molding ma-chine. Battenfeld showed a prototype 66-ton, tie-barless machine at an open house held June 5-7 at its factory in Kottingbrunn, Austria, Joanne McGovern, spokeswoman for Battenfeld of America Inc., said in a June 12 interview at Plastics Fair Chicago in Rose-mont, where the firm was exhibiting. Battenfeld surveyed about 500 customers who attended the open house, asking their opinions about tie-barless technology. The open house showed off an expansion of the Austria plant, done to build a larger-sized CDC injection molding press.
Tie-barless machines offer an advantage over machines with tie bars because they give unobstructed access to the mold area for part removal, changing molds and other work. Currently, Austrian press maker Engel Vertriebsgesellschaft mbH sells most of the tie-barless machines, but other companies are entering the market.
Battenfeld has not decided whether to produce tie-barless machines.
``It was shown to customers to get their opinions. This is not a production machine,'' McGovern explained.
David Tremblay, product manager at Battenfeld of America, said company officials hope to make a decision on whether to enter the tie-barless market by the end of the year.
At the Chicago show, Batten-feld of America, based in West Warwick, R.I., was showing the bigger CDC injection press for the first time in the United States. A 200-ton press molded a polystyrene part for a drill housing motor.
Previously, Battenfeld had produced CDC machines with clamping forces up to 110 tons.
Battenfeld headquarters is in Meinerzhagen, Germany.
