What is a plastic pendulum impact testing machine?
In the field of industrial production and quality inspection, the plastic pendulum impact testing machine is a common testing equipment, mainly used to determine the impact resistance of plastic materials under impact load. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the plastic pendulum impact testing machine to help readers fully understand this equipment.
1. Definition of plastic pendulum impact testing machine
The plastic pendulum impact testing machine is an instrument used to test the impact strength of plastic materials. It evaluates the material's toughness and impact resistance by simulating the impact that the material may be subjected to in actual use. This equipment is widely used in quality control and research and development in plastic products, composite materials, rubber and other industries.
2. Working principle
The working principle of the plastic pendulum impact testing machine is based on the law of conservation of energy. During the test, the pendulum is released from a certain height and impacts the sample. By measuring the energy difference before and after the pendulum impact, the energy absorbed by the sample is calculated to evaluate the impact resistance of the material. The specific steps are as follows:
1.Sample preparation: Process plastic materials into standard size specimens.
2.pendulum release: The pendulum falls freely from the preset height and hits the sample.
3.Energy calculation: The sensor records the energy change before and after the pendulum impact, and calculates the energy absorbed by the sample.
4.Result analysis: Evaluate the impact resistance of the material based on the amount of energy absorbed.
3. Application fields
Plastic pendulum impact testing machines are widely used in the following fields:
