Features of Pincer Grips

These grips are primarily used for testing highly ductile plastics and elastomers. The pincer principle produces a strong increase in gripping force during the test.

  • The gripping force is proportional to the tensile force (self-clamping).
  • The lateral mobility of the pincer grips allows specimens always to be loaded centrically to the test axis.
  • Design ensures fast, easy clamping.
  • Good high-temperature resistance and low overall height make these grips highly suitable for use in temperature chambers.Opens internal link in current window
  • These grips are frequently used for tear growth or peel tests as the upper grip element.

The pincer grips are opened and closed via a lever. Spring pre-tensioning holds the grips open for insertion of the specimen and the pincer action generates the pre-load force at the beginning of the test. The pincer action induces automatic re-tightening as the tensile force increases. This is advantageous with specimens which decrease in section during testing.
