The Digital Charpy Impact Testing Machine is primarily used for determining the impact toughness of non-metallic materials including hard plastics, reinforced nylon, glass fiber reinforced plastics, ceramics, cast stone, and electrical insulating materials. It serves as an ideal testing equipment for the chemical industry, scientific research institutions, universities, quality inspection departments, and other similar entities.
Working Principle:
A pendulum hammer with known energy strikes the sample supported on a horizontal beam, destroying the sample with a single impact. The impact point is centered between the two supports. By calculating the energy difference of the pendulum before and after impact, the energy absorbed by the sample during destruction is determined. The impact strength is then calculated based on the original cross-sectional area of the sample.
Instrument characteristics:
The instrument uses high-hardness precision bearings and a single-axis photoelectric sensor to fundamentally eliminate friction-induced losses, ensuring frictional energy loss is far below standard requirements.
It intelligently prompts the working status based on the impact conditions, maintains real-time interaction with the experimenter, and ensures the test success rate.
