NIIGATA MD-S8000 SERIES
JAPANESE PRECISION
The MD-S8000 Series from Niigata represents the pinnacle of all-electric injection molding technology. Manufactured entirely in Japan, this 8th-generation lineup delivers unmatched reliability, speed, and precision—qualities that have defined Niigata since introducing its first all-electric press in 1991.
Covering a wide machine range from 55 to 393 US tons and shot sizes from 0.7 to 59 oz. (PS), the MD-S8000 Series offers flexibility for a variety of molding applications.
Its toggle clamp mechanism and touch screen interface ensure efficient operation and ease of use for operators of all experience levels.
What sets the MD-S8000 apart is its intelligent balance of speed and control. Fast injection rates are coupled with advanced clamping precision, providing consistent, high-quality results even in demanding production environments.

ALL-ELECTRIC SERVO DRIVES
High performance electric servo drives provide the clean, quite and highly repeatable machine operation.
POWERFUL INJECTION UNIT
Niigata's original 2-axis structure provides a strong centralized injection force. Equipped with a wear-resistant screw and barrel.
DOUBLE LOW-PRESSURE MOLD PROTECTION
• Small resistance change is detected by tie bar sensor
• Object detection between molds by monitoring motor torque → Precise detection using optimized motor torque
• Protects molds by detecting guide bush, angular pins, slide core failure
HIGH PRECISION ELECTRIC CLAMP
The 5-point-toggle-system increases the platen intensity, reduces platen inertia and joint stress. The optimized mechanical structure provides more efficiency and a quiet machine operation.
MOLD DEFORMATION PREVENTION
Toggle links behind moving platen are connected ⇒ platen rigidity increased (RST design)
Even clamp force distribution by center press structure ⇒ Deflection (platen deformation) reduced by 40%
NOZZLE GROUP TEMPERATURE CONTROL
2 Heaters are controlled using 3 sensors
Sensor positions can be virtually changed by weighting sensors
Stable control of temperature gradient of nozzle and nozzle tip
Optimized resin temperature inside nozzle prevents cobwebbing, drooling and clogging
LATEST SOFTWARE & CONTROL
15" High resolution touch screen supports your smart operation with clear view and highly responsive touch interaction. Molding data or graphs can be displayed while you work on the injection setting. HOME screen is an integrated screen with setting entry fields and molding data. Individual windows such as graph, molding data and electricity consumption can be displayed by pressing function keys beside display and these windows can be overlapped on the screen.
