![]() The system is available in eight, 16 or 24 cavities, which will accommodate preforms with threads having a maximum diameter of 63mm, 43mm and 30mm, respectively.

On the take-off plate side, the main plate remains in the machine and the cooling tubes are removed in individual rows called take-off bars. “Instead of replacing the ejection cams (preform design related) with a conventional mold approach, Flex Mold uses a new concept of adjustable stroke cams that save both time and money.” “The simplified design means that only a portion of the cavity must be replaced for a conversion, since the gate pads remain on the hot runner,” Sigler continues. *assumes one skilled operator, working aloneįaster changeover times and low tooling costs. Change times can be reduced to as little as a third of the time it takes to switch a conventional mold. It also cuts cost by minimizing the number of components to be replaced while easily accommodating any preform length. “The mold’s unique design eliminates the need to cool down and reheat the hot runner during a part changeover, which greatly reduces system downtime. This system’s modular design provides many benefits during conversion, Sigler explains. ![]() Flexibility, ease of use and lower conversion costs are what customers need.” “After talking to potential customers in this market segment, we realized that cycle time was not the number-one driver for these applications. “The technology also is helping converters expand into new markets because they can now pursue niche or developmental projects that were previously not financially feasible,” Sigler explains. The introduction of Flex Mold will allow Husky to meet the needs of lower volume, custom preform and bottle producers, particularly those producing between five to 30 million units each year, according to Laurent Sigler, Husky’s Business Manager New Technology. It also benefits manufacturers that produce a range of preforms with the same neck finish, but for different sized applications. (Bolton, ON)-a worldwide supplier of injection molding equipment and services to the plastics industry-Flex Mold is ideal for preform and bottle producers using one machine for multiple applications, that must be able to change molds with minimal downtime. Unveiled at Chinaplas 2008 by Husky Injection Molding Systems Ltd. A flexible and cost-effective PET system featuring modular, low cavitation PET preform molds reduces both conversion costs and mold changeover time.
