High-cycle screw (UB-HC screw)

Screw wear prevention technology High mixing Uniform plasticization PP resin Plasticizing capacity High mixing Uniform plasticization Unmelted resin

Introduction to Technology
High-cycle screw HC-UB screw
HC-UB screw
Objective
  1. Special PP, PE higher cycles
  2. High mixing, uniform plasticization,
Effect
  1. High mixing, uniform plasticization, unmelted resin does not mix, uniform plasticization quality
  2. Example of high plasticizing capacity
    • Injection molding machine: 850 tons
    • Molded part: container
    • Resin: PP
    • Molded part weight: 2.7 kg
Stop time and plasticizing capacity of resin (test cycle [test conditions: plasticization 25 seconds, screw stop time: n seconds]) graph
Content
  1. Screw L/D = 22
  2. Control fouling of screws and cylinders as well as wear and tear using a step land.
  3. Shorten plasticization time with the use of a long barrier equal to or more than a conventional UB screw.
Screw (step land flight, conventional UB barrier zone, long barrier zone)

Screw wear prevention technology
Step type flight
Generation of fluid lubrication force by improving the shape of the screw flight

Application
  1. Bumper
  2. Container
  3. Others, PP, PE molded parts
