impact testing machine for plastic is used to determine the impact toughness of non-metallic materials such as plastic, reinforced nylon, glass fiber reinforced plastic, ceramics, cast stone, plastic electrical appliances, and insulating materials. Pendulum impact testing machine is a common equipment for quality inspection by scientific research units, colleges and universities, and non-metallic material manufacturers. The machine is a simple structure, easy to operate, and high precision instrument. The digital display impact testing machine adopts high precision. Encoder technology has the characteristics of high accuracy, good stability and large measuring range. The digital measurement shows the impact strength and average value, the energy loss is automatically corrected, and the test report is printed.
