StackTeck Systems Ltd. (Brampton, ON, Canada), a global manufacturer of multi-cavity, high-volume production molds for thin-wall packaging and closures, is displaying a first at NPE2018: The company’s newly developed servo In-Mold Closing (IMC) technology. The IMC system is running in the Wittmann Battenfeld booth (W3742) on an EcoPower 180/750 machine with fully integrated Wittmann 4.0 auxiliaries, including a W833 Pro Robot.
The new IMC technology is used to demonstrate a 1 x 4 flip-top closure mold featuring a servo-actuated IMC mechanism. Compared to a conventional IMC mold with a cycle time delay of 1.5 seconds for closing, this new servo mechanism from StackTeck actuates in 0.35 seconds, representing a 75% reduction in closing time, said the company.
StackTeck has also used a KoolTrack mold stack design for optimal cooling, resulting in reduced hold/cool time and an overall cycle time that is three to four seconds faster than a conventional flip-top closure mold.
The servo-drive technology is suitable for unscrewing and flip-top caps through a simple interface to the molding machine. The NPE2018 show mold includes its own stand-alone servo control cabinet and pendant, which uses a standard Euromap robotic interface to the injection machine.
The arrangement of the IMC mechanism remains the same as StackTeck’s proven existing design, which has a successful track record of production molds with over 1,000 cavities with a single servo drive mounted at the top of the mold. The complete mold and control system are well suited to mold changes between different standard machines.
