Custom-production of all kinds of tension clamp, tension weight, pre-weight/pre-hang heavy weights
When staple strength and elongation measurements, we need to give the fibers a pre-tension, the usual practice is: the end of the fiber caught in the holder, and the other end with a pre-tension clamp onto the fiber hang freely, to be fiber still down when the reuse of a holder clamped the other end of the fiber, the two gripper spacing is fixed value (ie holding distance). This time it that the fibers have been applying a pre-energizing, the pretension of a size equal to the weight of the pre-tension clip. When the test on the holder fixed under the holder under the control of the instrument will be vertically uniform stretching. Until the data that is able to meet our requirements. This value ranges and error pretension clip in the national standard GB and international fiber strength and elongation measurement criteria are clearly defined.
We offer alligator clips, O type clamp jaws sip great degree. Also available: Hook weights, sheet type weights, according to user requirements of special processing.
