NN Series


  • Shorten the molding cycle
  • Improve the production efficiency
  • Improve the quality of products


Intercepting a injection molding machine nozzle is mainly used for the injection molding process does not allow the nozzle mouth have salivate and filaments of injection molding, mould material, through the adoption of side side of the production process in the process of the mold (or storage), so as to shorten the production cycle, improve production efficiency. This product is mainly used in packaging, automotive and leisure industry, medical and electronic equipment, and other fields, as well as the physical foaming, melt flow preloading, hot runner injection molding and other special industry.


  • Through implement active control opening and closing machine signal, control precision rapidly
  • Through the lever mechanism axial movement and position control of the needle valve, it can realize accurate intercepting melt in mouth nozzle parts
  • Leveraged institutions can through hydraulic or pneumatic control
  • Loss of the injection pressure is small, often used for high speed machine, can shorten the molding cycle
  • In the nozzle mouth to truncation of the melt, strong and durable, truncation, reliable and can be used for special purposes
  • Can prevent filaments, as well as prevent salivate, used for precision injection, etc
