Pneumatic air grips and clamps

Pneumatic air grips and clamps use air pressure to provide constant clamp loads to tensile test specimens. They perform High volume tests where opening and closing actions are repetitive, Sensitive or fragile test samples where clamping can cause failure or where multiple tests are performed. Many times, it can be desirable to test all samples under constant clamping conditions. The are ideal for film testing applications and other High elongation tests where the samples shrink as they are pulled. If the sample stretches (e.g. plastics and rubber), the sample can pull out of mechanical action clamps. Air cylinders can adjust to the changing conditions and hold -- regardless of sample deformation. Air grippers are also used for testing materials such as Textiles, Geotextiles, Sheets, Thin Films, Foils - Flat specimens, Thread, wire, rope – Round shapes, Soft materials, Lap Shear samples, Soft Tissues & Medical Devices, Peel and adhesion tests, and Delicate films, polymers woven fabrics.
