Abstract: Charalcteristics of conventional measurerment methods of clamping force repeatability was discussed. Influencing factors on clamping force repeatability were invest igat ed by Baumer strain clamps (Switzerland) . It was found that the influences of variatlons of mold closing/ opening position and speed could be neglected. The test methods of clamping force repeatability based on Baume strain clamps had characteristics of easy operation and high accuracy.
