SynFlow® Two-Speed Sequential Valve Gating

SynFlow® is a two-speed pin control technology for cascade or sequential valve gated hot runner systems. The initial opening speed of the valve pin is reduced to prevent an explosive rush of pressurized plastic. The valve pin then opens for the remainder of its stroke at maximum speed to properly fill the part.
This patented process enables a smooth fill, reducing hesitations and sharp velocity changes. The result for you: cleaner parts with perfect surface quality, and improved process efficiency.

 

Features and Benefits

  • precise control of the opening profile
  • real-time valve pin position monitoring
  • reproducible velocity regulation
  • prevents molding defects such as:
    • flow front disturbance marks
    • marks opposite direct gating
    • sink marks after painting process
    • delamination defects
    • reduced adhesion of coatings
