Electropunch Series Impact Hammer Information

Model C
Our most powerful and heavy duty electropunch with impact forces ranging up to 15,000 lbs. Ideal for light taps to heavy impacts.

Model JS & FJS
Popular for machine tool builders that are looking for an impact punch that is easily adaptable into an assembly system due to the flange style mounting design. Model FJS includes a frame, serving as a bench top press.

Model BS
Our most popular and flexible unit because of its column mounted design. This gives you the ability to easily adjust the working height for a variety of different job set-ups.
We also produce a Model SMS electric impact hammer, which consists of a hold-down mechanism to keep parts steady before an internal spindle fires to stake the parts together — contact us for information.
