Clamping
Pressurex® is a thin flexible mylar film that reveals pressure distribution and magnitude between any two contacting surfaces. Pressurex® can determine both the magnitude and distribution of pressing forces during spot, projection and seam welding, as well as pressure on welding fixtures and jigs, and resistance welding heads. The integrity and efficiency of any clamped fixture or fastener can be evaluated with Pressurex.
Upon the application of force the microcapsules rupture, producing an instantaneous and permanent color change. Like Litmus paper, the color intensity of Pressurex® is quantifiable; the color intensity reveals precisely what pressure level (PSI or kg/cm²) was applied at any discrete point on the surface of the film.
