Intelligent hybrid X-pump system
Hydraulic and electric molding machines have different advantages in mechanical and molding characteristics due to the differences in the driving source and its method. While electric machines are becoming mainstreams today, we have created the Nissei Original Hybrid Injection Molding Machine PNX/FNX Series, combining the advantages in both hydraulic and electric types.

Its high-rigidity direct clamping system, excellent injection performance, long lasting & easy maintainability, and electric machine level of energy saving offer an outstanding total balance, enabling it to perform a versatile range of moldings from thin-wall to thick-wall products. Nissei hybrid type machines will revolutionize the concept of hydraulic injection molding systems.
Servomotor rotates at required speed only when it is necessary.

Revolution speed control pump driven by AC servomotor
  • Substantial energy-saving is possible since the motor is at rest during unloading.
  • Arbitrary selection of standard/high-velocity I/high-velocity II injection modes changeover permits wide-ranging injection from ultra-low speed to high-speed.
  • The injection holding pressure control (pressure controlled state) can be sustained
Improved molding stability
Weight deviation of molded products ... reduced to 1/3
Achievement of Substantial Energy Savings

By equipping the X-pump, energy efficiency has been improved substantially, permitting the suppression of temperature rise and reduction of the amount of cooling water.

In addition, the operation cost of water cooling systems, such as a cooling tower, can also be reduced.

Stable long-term operation of “direct-pressure” type clamping mechanism
  • The advantages of direct-pressure clamping mechanism:
    Long stroke, stable clamping force, clean mechanism, high-performance low pressure clamping, easy setup of optimum (low) clamping force, easy mold change, long-lasting, low-maintenance, etc.
  • It is equipped with a mold open/close stabilization control. Mold open stop position and slowdown changeover position accuracies have been improved, and smoother mold open/close operation has been materialized.
  • The parallelism can be maintained for a long time by its proven outstanding performance of the direct-pressure clamping system.
  • The clamping stroke is long, making it effective for thick molds, such as hot runner, deep well, and three plate molds.
  • Wide platen (FNX80~220)…one class larger mold can be mounted.
  • By “Very Slow Mold Open” mode (FNX80~360), the low speed stability during product ejection has been greatly improved.
  • A clamping pressure rise confirmation sensor has been added, enabling it to set the clamping force below 60% (10~100% setting is possible).
    ...Recommending optimum (low) clamping force setting = friendly to machine and mold.

Outstanding injection performance
  • Wide-ranging injection speed…from ultra-low speed (0.004 in/s) to high-speed (max. 21.7 in/s with PNX40-2A) range.
  • Excellent controllability and stability in ultra low speed range (under 0.04in/s).
  • High injection response…response time max. 48ms (with PNX40 normal mode).
  • Higher injection pressure…AA screw are used on 9A~25A type injection units, increasing the pressure up to 20%.
  • Outstanding injection holding pressure performance…”high-pressure + long-sustained” injection holding pressure is possible.
  • Product weight deviation suppressed to 1/3 by precision metering control.
  • Optimum barrel temperature control zone and detection points configured to materialize ideal temperature distribution.
  • 5-zone temperature control of the nozzle and barrel + monitor display of hopper throat temperature.
