We manufacture compact, rigid, and accurate high-performance injection molding machines with multiple pre-engineered options for customization. The machines incorporate the latest servo ball screw and pump technology.

Modular and scalable controls featuring distributed inputs and outputs allow easy customization. Features include an 800 µs reaction time, full data transparency, machine life cycle monitoring, and "heartbeat" functionality. Standardized interfaces allow machines to be integrated in Industry 4.0 smart factories.

Third-party equipment can be controlled through the machine's HMI. This allows mold servomotors for in-mold actions, such as unscrewing and closing, to be built into the machine cycle sequence, along with torque and power tracing.

  • Clamping forces between 150 and 550 metric tons
  • Reciprocating screw and two-stage injection with screw diameters ranging from 30 to 140 mm

Fastest to market: The wide range of pre-engineered options leads to reduced development time and the capability to quickly integrate customers' requirements.

Pre-engineered options:

  • PET
  • Cube
  • Stack
  • Two-material
  • Robotics
  • Unscrewing
  • Integrated 3rd party hot runner controllers
  • Modular ejectors
  • Integrated servo functions



  • The industry's most rigid and accurate bases and platens
  • Reduced machine and mold maintenance
  • Best-in-class mold capacity (by size and weight)
  • Energy efficiency as good as, or better, than all-electrics
  • Smallest floor space
  • Clearance under the machine for cleaning
  • All services at injection end

Servo driven gear pump(s) operate on demand for plasticizing, injection, clamp force build-up, mold break, nozzle pressure, auxiliary motions, nozzle opening, ejector assist. Electric servo drives operate the mold stroke, ejector, and clamp lock.

Energy consumption is lowered through the use of an active power supply that regenerates power – instead of being converted to heat; kinetic energy generated during braking is regenerated into the power supply system.
