Preform Mold Technology Increases Flexibility

 
      A flexible and cost-effective PET system featuring modular, low cavitation PET preform molds reduces both conversion costs and mold changeover time.

    Unveiled at Chinaplas 2008 by Husky Injection Molding Systems Ltd. (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. It also benefits manufacturers that produce a range of preforms with the same neck finish, but for different sized applications.

    Meeting Customer Needs

    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. "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. "After talking to potential customers in this market segment, we realized that cycle time was not the number-one driver for these applications. Flexibility, ease of use and lower conversion costs are what customers need."

    How It Works

This system's modular design provides many benefits during conversion, Sigler explains. "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. It also cuts cost by minimizing the number of components to be replaced while easily accommodating any preform length. Change times can be reduced to as little as a third of the time it takes to switch a conventional mold.

    "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. "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."

    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. This eliminates the time and effort required to align the take-off and CoolPik plates for each removal.

    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.

    "Advantages of the new systems are numerous," Sigler concludes. "It offers uncomplicated solutions with a simple cavity lock stack design and adjustable ejection cams. Quicker mold changes are possible because the hot runner and take-off plate remain inside the machine and the same CoolPik plate and pins are used for most preforms. The mold water purge system is built into the machine and each mold half includes one water in and one out-which also saves time."
