Digital Puncture Tester

Digital Puncture Tester

To determine the absorbed energy or puncture resistance of corrugated and compact cardboard, especially those employed in the manufacture of packaging. Puncture resistance has become increasingly important, and many countries have included this indicator in the quality specifications of corrugated cardboard. The PT-48 Digital Puncture Tester measures the ability of corrugated cardboard to resist puncture, changing positional energy before and after perforation of the cardboard, and transforming the change in potential energy into kinetic energy to perforate and tear the cardboard. in the puncture test according to international standards, the use of a pyramidal puncture head causes the material to load in all spatial directions. During this process, combined tensile, compressive, bending, and shear forces are produced. The result obtained in this test is the energy absorbed in the perforation of the material. To do this, a dynamic pendulum dynamic drilling testing machine like the PT-48 is used.
