Blog

Welcome to our new Instron Community Blog hosted by Instron. It is a compilation of the freshest, brightest, most-talented minds that Instron has to offer. The world of materials science is so vast and encompasses the broadest range of industries, materials, and challenges that no one person can possibly possess all the knowledge required to be the resident expert – or master of materials science. It takes a small army behind the scenes collaborating and sharing technical know-how, experiences, and ideas to present the most accurate, relevant, and timely information to you – our readers. 

We invite you to tell us who you are, share your stories and talk about your experiences. Join the Instron Community. 



Wedge Action Grips: Which is Moving?

Wedge action grips are a very popular choice for gripping high-strength materials, such as metals and composites, because the strong clamping force ensures that specimen slippage is eliminated. All wedge grips work by multiplying a relatively small input force into a higher clamping force. In all wedge grips, the opening and closing of the jaw faces are achieved by the relative motion between the grip body and the jaw faces. However, there are two distinct wedge grip designs – “moving jaw face” and “moving grip body”. Their difference lies in which component is kept stationary and which is moving.
