About X-Pump System |
|
|
| |
| |
 |
|
Flow...revolution speed of a servomotor
Pressure...torque of a servomotor |
Servomotor rotates at required speed only when it is necessary. |

|
Patent pending |

|
|
|
|
|
|
| |
|
|
|
|
| |
It is a revolution speed controlled pump driven by an AC servomotor
|
|
|
| |
-
Substantial energy-saving is possible since the motor is at rest during unloading.
-
Injection modes changeover permits wide ranging injection from ultra-low to high speed.
-
Injection holding pressure control (pressure controlled state) can be sustained for extended period.

Injection Performance Advancement by X-Pump |
|
| |
-
In comparison with the conventional hydraulic machines, it achieves faster injection velocity and quicker injection response.
-
“Excellent stability in ultra-low velocity/pressure range,” which is difficult to
achieve with the hydraulic machines, has been materialized.
|
| |
|
|
|
|
| |
In comparison with the conventional hydraulic machines, it offers superior lowest operational velocity/pressure and higher resolution in low-velocity/pressure range. |

The Ultimate Level of Energy Saving Materialized |
|
|
| |
|
|
|
Since the servomotor in X-Pump system rotates at required speed only when
it is necessary, it is extremely efficient. In comparison with the conventional
hydraulic machines, its motor consumes approximately 45% less energy. |

Stable Long-Term Operation of "Direct-Pressure" Clamping Mechanism |
|
| |
The advantages of direct-pressure clamping mechanism:
long stroke, stable clamping force, clean mechanism, high-performance lowpressure clamping, easy setup of optimum (low) clamping force, easy mold change, long-lasting, low-maintenance, etc.
|
| |
|
|
|
|
●
● |
The simultaneous motion of “ejection during mold opening” is possible.
Mold open/close stop position accuracy has been significantly improved.
|
| |
o Up to 50% less fluctuation in mold open stop position.
→ Prevents takeout robot errors.
o Overrun against stop position setting improved.
→ Enhances low-pressure mold clamping performance (mold protection function).
o Less fluctuation in mold open stop position after changing the opening speed. |
●
|
The mold clamping mechanism of 3-plate (direct pressure) type is simple and excels in rigidity and durability. Thus, the deflection of movable platen is small, and it maintains the parallelism for a long time. |

|
|
| |
● |
Wide platen and long clamping stroke make it effective for molding larger products and mounting thick molds (hot runner, deep well, and three plate). |
| |
● |
It is easy to configure low (optimum) clamping force and is effective for conserving energy, prolonging the life of machine and mold, and measuring defects, such as gas vent issue and short shot. |

FVX860 Stationary Platen |
|
● |
It is a complex clamping type, its motion is continuous from high speed clamping to high pressure clamping, and there is no lag time for switchover. It materializes high-cycle and stable molding with its smooth mold open/close motions. |
|
| |
|
● |
The structural analysis by finite element method has been conducted when we designed the stationary and movable platens, and it maintains high machine precision and rigidity for a long time. |
