TENSILE SPECIMENS PUNCHING KNIFE

In the tensile strength testing of plastics, appropriate tensile specimens are used, which can be produced using a specimen punch and a punching knife. Due to the precise dimensions of the punching knife, tensile specimens made from the same materials are largely reproducible according to DIN ISO 527-2 Type 1/A - 1B - 1BA / ISO 527-3 Type 2 / DIN 53504 - S1 - S2 - S3a - S3 / ISO 37 1 - 1A - 2 - 3 - 4 / ASTM D 624. Punching tools for thermoplastics or rigid PVC consist of a punch and die, as well as a blank holder and guide.
