Electric valve gate systems

At The Tool Hub we constantly see new technology in the industry and one that is now adding performance to our tools is the electrically controlled valve gate system.

In the old days only hydraulic or pneumatic movement of the pin was a possibility, that is digital technology that only gives you the option of open or closed.
Now we are often recommending electric movement that is precisely controlling each valve pin’s position, acceleration, velocity and stroke.

Injection molding applications that require sequential molding and premium cosmetic surfaces specifically call for the benefits provided by the eGate technology. It is ideal for molding applications where precision and control are critical.


  • Optimizing balance in multi-cavity and family molding.
  • Optimizing surface quality of sequential or cascade injection molding.
  • Pin movement in less than 0.1 sec and closing forces equivalent to hydraulic systems.
  • Pin stroke to be changed with the touch of a button.

Most of our hotrunner suppliers are now able to supply these systems.
