More enhanced productivity
Ultra high mixing screw
  • Able to obtain a moldability equal to or more than the current moldability for PP, PE, and PS by using a UB screw provided with special mixing on the tip.
    Two types of UB screws can be selected depending on the application.
Special mixing
Mixing type 1: MD-UB screw
Extremely high-level uniform melting is obtained for PP, PE, and PS by using optimal shearing and partitioning actions of a multi dam that has a polygon cross-sectional shape. As a result, stable molding of large, thin walled molded parts is possible.
MD-UB screw
Mixing type 2: MF-UB screw
The efficient dispersal effect of melted resin with the use of the optimal design of tip Dulmage type screw is effective in eliminating color heterogeneity for materials in which color heterogeneity easily occurs for PP as well as for combinations of master batches.
MF-UB screw


Holding pressure, plasticizing lap circuit
  • Allows plasticization during holding pressure process and is effective when plasticizing capacity is not sufficient.
Gate valve open Shutoff nozzle for high pressure closed


Hydraulic operated shut-off valve
  • Rotary type: Dripping prevention and high-speed injection
Rotary type
  • Needle type: Dripping and streaming prevention
Needle type


Mixing nozzle
  • Mixer unit has an easy-to-clean construction.
  • Different types of mixers are prepared and can be selected depending on your goals.


Hydraulic ejector differential circuit
  • Increased return speed (approximate twice) and shorter cycles.


Gate valve
  • Hydraulic opening and closing gate.
  • Please contact us with the desired specifications for the number of gates and the timing for opening / closing.


Double plasticization circuit
  • Rotates the screw again during extraction time.
