JETMASTER C3 Large Series Large Tonnage Injection Machine 

(650 to 2000 tons) (650 to 3000 tons)


The JETMASTER C3 Large series of energy-saving injection moulding machine, with clamping force ranging from 650 tons to 3,000 tons, is your ideal partner for producing a wide variety of goods including automotive components, industrial containers, large household appliance parts, and furniture. The optimized fixed and moving platen designs maximize space between the bars and daylight area while providing superior mechanical accuracy and enhanced structural integrity. The hydraulic circuit design is modular, which not only provides flexibility but also enables overlapped cycles, simultaneous operations, and advanced hydraulic circuitry can usually reduce electricity consumption by 40-50%* or more compared with standard fixed-pump systems, while the all-electronic closed-loop system+ provides significantly improved proportional flow and pressure characteristics.

Injection Unit

  • High resolution potentiometers provide superior positional control precision
  • Nitrided injection screw and barrel with supreme anti-wear properties and long useable life
  • Compact twin injection cylinder design
  • Back pressure control
  • Balanced dual-cylinder design provides secure holding pressure for injection carriage and prevents drooling (on certain models)
  • Screw and barrel maintenance are made easy with pivot cylinder to turn injection unit (on certain models)
  • PID barrel and nozzle temperature control ensures high melt quality
  • Radial piston-type hydraulic motor drives the screw directly. The high torque is able to process a wide range of materials with optimal melt quality and mixing, effectively shortening recovery time
  • Cold-start prevention ensures that the screw does not rotate until the preset temperature profile is reached
  • Bosch high-frequency-response servo proportional valve is equipped with LVDT position feedback. Together with high-precision pressure feedback from the outer control loop, it delivers supreme injection speed and pressure control performance
  • Optional feature: Chen Hsong’s exclusive D-Wave screw is particularly suitable for producing large parts with superb mixing and high-quality melt

Exclusive Circular Platen (Patent)

China Utility Model Patent ZL01 2 57876.2

  • Even stress distribution to moulds, improves production stability and quality
  • Greatly reduces stress concentration, lengthens mould life
  • Enhanced stress distribution, guaranteed for ten years#

Closed-Loop Energy Saving Device

  • All-electronic variable-speed hydraulic energy-saving technology from Germany and Japan is a supreme energy saver with significantly enhanced proportional flow and pressure characteristics. When compared with standard fixed-pump systems, electricity consumption can usually be reduced by 40%* or more
  • Quality assurance
  • Energy loss and system heat build-up are minimized as flow and pressure are controlled according to actual demand. Lower oil temperature reduces expenses in cooling devices

*Subject to different product application and cycle times. Energy saving device is an optional feature.

+Closed-loop hydraulics is an optional feature

#Under correct use and norma

Clamping Unit

  • T-slot arrangement for easy mould fitting (Optional)
  • Designed via finite element analysis with a focus on high structural integrity
  • Adjustable slider supports movable platen
  • High-tensile tie-bars, induction hardened, with chrome-plated surfaces
  • Automatic mould height and clamping force adjustment
  • Electrical, mechanical and hydraulic safety devices
  • Regenerative hydraulic circuit shortens cycle time and enhances efficiency
  • Multiple cooling water distributor
  • Electrical/ pneumatic automatic front guard door (on certain models)
  • Low pressure mould protection feature effectively prevents mould damage
