Threaded Nozzles

In the 09E, Synventive Molding Solutions GmbH, Bensheim, Germany, has launched another threaded nozzle onto the market that forms a leakproof unit with its “plug-and-play” hot runner systems. The 09E threaded nozzle family is available with both open gate and valve gate options. With a flow bore of 9 mm (with 30 mm mold cut-out), it is ideal for medium-sized plastic parts and maximum shot weights of 250 g per nozzle. As the nozzles are threaded directly into the hot runner manifold, a leak-free system is obtained, without critical stack-up dimensions having to be maintained. The 09E nozzles are externally heated and available in lengths of 60 to 400 mm. The heaters, which have integrated, replaceable thermocouples, are easy to replace and, where longer than 180 mm, are equipped with two heating zones for optimal and individually adjustable temperature balance in the hot-runner nozzle.

The “plug-and-play” systems are fully pre-assembled, tested and shipped ready to install. Time-consuming work spent on installing and adjusting the hot-runner system in the mold is considerably reduced. According to the manufacturer, the systems are designed for use in applications demanding high parts quality, including those in the automotive industry and the consumer and electronics markets.
