Information on the most widely used ASTM standards within the materials testing industry
Model: QK-20, Manual
QK-20 notch sample reparation machine is used to process the non-metal material impact test specimen notch, such as the plastics, organic glass etc., it’s an ideal notching machine for plastic impact test. Surface with nickle coating, more reliable.
General introduction
QK-20 notch sample reparation machine is used to process the non-metal material impact test specimen notch, such as the plastics, organic glass etc., it’s an ideal notching machine for plastic impact test. Surface with nickle coating, more reliable.
