How many kinds of impact testing machines are there?

From the test materials: metal testing machine: mainly for the impact performance test of various metals, usually the impact work is relatively large; Non-metallic testing machine: testing the impact properties of various plastics and rubbers, and the impact work is usually small. In terms of test methods, hammer impact tester is divided into semi-automatic pendulum impact tester, microcomputer screen pendulum impact tester, normal temperature automatic pendulum impact tester, low temperature automatic pendulum impact tester and high and low temperature automatic pendulum impact tester. The automatic pendulum impact tester consists of an impact host, a control system, a sample box, a feeding mechanism and a positioning mechanism. Press the button to complete a series of actions and get the test data to complete the whole impact test. Low-temperature automatic pendulum impact tester: It is composed of main engine, control system, refrigeration system, sample box, feeding mechanism, positioning mechanism, etc. After reaching the set temperature, a series of actions can be completed and test data can be obtained by pressing the button, and the whole impact test can be completed, with convenient operation and reliable performance. The equipment greatly shortens the time from the low-temperature box to the completion of the impact test, and improves the accuracy of the test, the efficiency and safety of the pendulum impact test. Low temperature range: room temperature ~ 196℃. High-low temperature automatic pendulum impact testing machine: it consists of impact testing machine host, control system, refrigeration system, high temperature box, sample box, feeding mechanism, positioning mechanism, etc. After reaching the set temperature, only a series of actions such as pressing keys are needed to obtain the test data to complete the whole impact test, with convenient operation and reliable performance. The equipment greatly shortens the time from the environmental box to the completion of the impact test, and improves the accuracy of the test, the efficiency and safety of the pendulum impact test.
