Hydraulic and electric molding machines have different mechanical and molding characteristics because of the differences in the driving source and its method. While electric machines are becoming mainstream today, the fusion of the hydraulic and electric machines has given birth to the Nissei Hybrid Series. The Series is equipped with the new-concept “X-Pump System” to deliver outstanding performance, in which conventional variable-displacement hydraulic pumps have never achieved.
Energy saving...
Almost equivalent to that of electric molding machines (A maximum of 55% reduction as compared with conventional hydraulic machines)
Quick response…
Injection response time: 40-50 ms (Standard mode)
Stability in low-velocity/low-pressure & wide range...
Injection velocity: From ultra-low (1 mm/s) to high velocity range
Linearity...
Excellent linearity in both injection velocity and injection pressure
Excellent injection holding pressure performance...
Capability in sustaining high injection holding pressure longer (as compared with electric types)
Reduction in the amount of hydraulic oil...
A maximum of 56% reduction as compared with conventional machines
Long lasting & low-maintenance system
Merits of direct pressure mold clamping
Excellent low-pressure mold clamping performance, clamping force is equal to the preset value at all times, and the clamping force is unaffected by climate changes
X-Pump System
Revolution speed control pump driven by AC servomotor
The motor is near at rest during unloading, permitting substantial energy saving.
The high-output volume changeover permits high injection velocity easily.
The low-output volume changeover excels in controllability in the low-velocity and low-pressure ranges.
Sustain injection holding pressure for a long period of time (pressure control state).
Servomotor rotates at required speed only when it is necessary.
Flow...revolution speed of a servomotor
Pressure...torque of a servomotor
