Electric Actuation: The New Generation of Motion Control in Plastics

Diakont roller screw actuators provide the ideal replacement for injection molding actuation systems, including:

  • Nozzle touch
  • Ejection
  • Core pull
  • Co-injection


  • Blowing rod
  • Die-Head
  • Clamping
  • Clamping
  • Cutting








Hydraulic actuation has been the standard for motion control in injection molding applications for generations, and yet every day more plastics manufacturers are turning to electric actuation for the greater speed, precision, energy efficiency, and other benefits offered by this innovative solution. Using advanced roller screw technology, Diakont electric actuators supply the high force required for motion control in injection molding processes, including core pull, hot runner direct nozzle and multi valve control, ejection, ram, and clamping, while entirely eliminating many of the problems associated with hydraulics. With no hydraulic fluid needed, electric actuation puts an end to internal leakage and frictional losses, as well as reducing the need for cooling requirements, resulting in significant increases to the overall efficiency of your toggle injection and clamping machinery.

Cost Savings through Energy Efficiency
The most immediate and drastic difference appreciated by customers who make the switch to electric actuation is the increased energy efficiency, which prompts enormous cost savings. Unlike hydraulic actuators, which continue to consume considerable energy even in their idle state, electric actuators consume only small amounts of energy while not actively engaged. Consequently, Diakont customers who convert from hydraulic to electric actuation report energy savings as high as 20%. In addition to impacting the bottom line, such a sizeable reduction in energy usage allows for a significantly improved environmental footprint.
Diakont: Engineered to Move
At a glance, the advantages of using Diakont electric actuators compared to hydraulic systems include:
  • Best-in-class lifetime (>10,000,000 cycles), owing to advanced roller screw technology
  • Featuring continuous forces up 9283 lbf
  • High temperature tolerance – up to 85˚C
  • Simplified set-up and superior precision (tighter position tolerances via digital control)
  • Easier and less frequent maintenance – patented lubrication ports facilitate scheduled maintenance, without requiring disassembly or recalibration
  • Quickly and easily retask the same actuator to complete multiple projects (simply plug in a laptop and upload a new motion profile)
  • Improved quality and durability in a lighter, more compact package
  • Increased cleanliness and safety plus reduced noise levels, improving conditions for workers
  • No opportunities for hydraulic fluid leaks
