Features the New TACTUS™ Controller

The EOS ST Series are two-platen clamp, servo-pump, hydraulic powered injection moulding machines available in 70-, 110- and 180-tonne models. An extremely compact footprint with very generous part drop area is achieved through the cantilever clamping unit design combined with a twin ram injection unit which features a hydraulic reciprocating screw. Injection capacities (g PS) range from 36 to 600 across the line. EOS machines are equipped as standard with:

  • NEW TACTUS™ Touchscreen PC with Powerlink, user-friendly interface with full range of control parameters
  • Highly efficient servo-motor driven gear pump system
  • Innovative cantilever clamping unit with very generous tie bar spacing to accommodate larger moulds, and a moving platen that rides on linear bearings, providing excellent parallelism between the platens and ensuring cleanliness in the moulding area due to the absence of lubrication oil
  • Robust twin cylinder injection unit
  • Extremely compact footprint
  • AMICO wireless remote service access

ST Servo Pump System

ST SERVO PUMP SYSTEM

CANBIO-ST-SERVO-PUMP-SYSTEM-2The EOS ST is powered by a servo motor driven gear pump system, using the very latest technology from renowned component suppliers such as Rexroth and Baumuller. The benefits of this system are many and offer a much greater overall efficiency, the most important of which are:

  • Improved process control reduces reject levels
  • Lower power consumption results in a lower cooling requirement
  • Much less noise for a better working environment
  • Longer oil life, longer lasting hydraulic components and reduced maintenance

These performance enhancements combine to produce a more profitable moulding process for the owner. This arrangement, coupled with special energy optimising software from Negri Bossi, provides the user with excellent energy efficiency, reduced power consumption, and a more profitable manufacturing process.

CANBIO ST Energy Consumption Chart 1

An analysis of energy consumption during the various phases of a typical moulding cycle shows that the servo pump solution produces a superior result, when compared to more traditional hydraulic power systems. The following is one example showing how the EOS ST provides the customer with important savings in energy usage.
