Motorized Notching Machine

The Motorized Notching Machine is designed to prepare standardized notched specimens for impact testing of rigid plastics and other non-metallic materials. It applies precise and controlled notching to cantilever and simply supported beam samples, ensuring repeatable and reliable impact strength measurements. The machine is suitable for laboratories in research institutions, universities, and non-metallic materials production plants.
