Features and instructions

  • No stringing, no drooling, no residue in the gate. Very good gate mark.
  • Because it can provide bigger gate size, therefore it is very suitable for big size injection molding. Also lower injection pressure and less stress during molding.
  • A sequence controlled valve gate system could help produce a no weld line part.  
  • We provide AVMT, SVDT, NL-SVDP, SVG types.

Introduction

  • For the valve pin bushing is integrated with the nozzle, the structure of manifold become very simple, and therefore this series is most suitable for the multi-cavity application.
  • There is a pin in the nozzle and drive by pneumatic or hydraulic to open or close the nozzle. When the valve pin open / close can control the melt filling.
  • Especially for the big gate design, the valve pin will seal the gate after packing process to prevent the stringing and get the unapparent gat mark.
