Star-Line Crown 01.072.64.12.140
Twelve with One Shot
Heitec Heisskanaltechnik GmbH, Burgwald, Germany, presents a new design of the Star-Line hot-runner nozzles in the form of the 12-cavity Star-Line Crown 01.072.64.12.140. The multicavity nozzle for side gating of plastic parts permits up to 12 cavities to be filled via one hot-runner nozzle. This minimizes the control complexity, since one control point is sufficient to monitor the temperature of twelve cavities.The design permits a large yield per unit area of mold, and considerably smaller mold dimensions.
The smallest possible sealing diameter is 64 mm. Up to twelve gating points, instead of the previous eight, can now be disposed on a disc of about 76 mm. The longitudinal expansion of the nozzle no longer plays a role as far a “shifting” of gating points is concerned, since this is compensated by the two-part construction of the nozzle body in the interior of the nozzle.According to the manufacturer, the nozzle is characterized by a very good thermal profile. It permits production without drooling or particles, and is consequently ideal for use in clean rooms. In addition, Heitec recommends the nozzle for producing challenging articles from single plastics.
