Mobile phone case tensile testing machine is a kind of equipment used to test the tensile strength, breaking strength, elongation and other properties of mobile phone cases. The following is the specific operation process of the mobile phone case tensile testing machine:

1. Preparation: Put the mobile phone case sample in the clamping device of the testing machine, adjust the width of the clamping device to match the sample, and then connect the power supply and operate the controller.

2. Set test parameters: Set the parameters of the testing machine according to the required test parameters, such as test speed, tensile force value, stop conditions, etc.

3. Start the test: press the start button, the testing machine starts to run, and stretches the mobile phone case sample until it reaches the set tensile force value or reaches the stop condition.

4. Record data: The testing machine automatically records the data during the test, such as tensile force value, elongation, breaking strength, etc., and saves them in the computer.

5. End test: When the test is completed, the testing machine will automatically stop and release the sample, and the sample can be taken out to complete the test process.

6. Data analysis: Analyze and process the test data through computer software, such as generating tensile curves, calculating parameters such as tensile strength, breaking strength and elongation of the sample, to evaluate the performance of the mobile phone case.

It should be noted that when conducting a mobile phone case tensile test, it is necessary to select appropriate test parameters and operating methods according to the characteristics of the sample and the performance indicators to be tested. At the same time, when operating the testing machine, relevant safety regulations and operating procedures need to be followed to ensure the safety and accuracy of the testing process.
