MD-S7000 Series (Midrange)

MD-S7000 Series (Midrange)

MD-S7000 Series (Midrange)

MD-S7000 Series All Electric Injection Molding Machine (Midrange Tonnage)

Featuring industry-leading powerful injection with ultra-low speed injection, the midrange tonnage MD-S7000 series delivers superior, stable performance.

Advanced Injection & Clamping Unit

Highly accurate clamping mechanism

Mold height detection encoder and tie bar sensor are equipped for accurate clamping force adjustment.

Powerful injection

A very long holding time of 70-100 seconds at 135 MPa is possible with our standard screw size, providing more than sufficient capability of thick-wall molding (*).

* Shown number is maximum capability and does not guarantee holding time during continuous molding.

Ultra low speed injection control

0.01 mm/s injection speed is made possible by utilizing a high resolution encoder. Advanced stability and repeatability are established for thick-walled molding.

BPF control Ⓡ (Balance Pressure Filling)

The screw temporarily stops during injection to adjust gate balance. Material flows without being forced, and gas is released.

CPF control (Constant Pressure Filling)

Filling speed is slowed down by controlling maximum filling pressure. As peak pressure is reduced when the filling process is completed, the controller changes to the next holding process smoothly without sudden changes.

Efficient Set Up Process


NHN (Niigata Hiper Navi)

Integrated information on a single screen.

  • Preparation screen assists molding set up.
  • Basic settings can be configured on the simplified Easy setting screen.
  • Advanced setting screen is available for detailed configuration.
Simple mold set up
  • Mold attachment, clamping force adjustment, and low-pressure mold protection can be completed with a simple procedure.

 

Running Cost Reduction, Maintenance-Related Improvement


Reduced grease usage
  • With the equipped highly sealed ball screw, grease usage is reduced significantly.
Visualized running cost
  • Energy consumption is shown on the display.
  • Molding monitor displays the energy consumption per shot.
Enhanced reliability
  • Control panel is sealed to protect from dust ingress and falling water.
  • IEC IP52 equivalent operation housing is equipped.
  • Routine maintenance reminders with checklist for periodic inspection points.
