How to use the heat deformation tester ? Heat deformation tester is used to test the degree of heat deformation of materials such as plastics and wire skins. It is also suitable for testing leather, plastic, rubber, cloth, deformation before and after heating. At a specific temperature, the specimen is freely placed in the testing machine for 30 minutes, and then sandwiched between the parallel plates of the machine, the specified load is added, and the temperature is placed for another 30 minutes, and the thickness difference before and after heating is measured by the gauge, the thickness difference is divided by the thickness before heating, in percentage, that is, the deformation rate.
Wewon’s heat deformation testing machine is a powerful tool designed for determining the heat deflection temperature and Vicat softening point temperature of non-metallic materials. Its unique feature of being able to lift and lower the specimen holder at the beginning and end of the test ensures an accurate and reliable result. The machine can be used to test a wide range of materials such as plastics, rubber, nylon, and electrical insulation materials. The test room is equipped with a square window, allowing for easy observation of the specimens during the testing process, enhancing the user’s control over the testing conditions and results.

When shopping for a heat deflection tester, analyze the different models available to determine which one best fits your needs. Compare and contrast the features of each model such as current capacity, temperature range, and testing parameters. You may also want to look into factors such as cost, warranty, and customer service. With a better understanding of the different types of heat deformation testers available on the market, You can make an informed decision that meets your specific requirements.
By the way, It’s important to consider the material being tested and determine the temperature range at which an accurate result can be obtained. Rubber and plastic insulated wires and cables have insulation that varies in thickness and composition, each having its own inertial resistance property, which translates to a different thermal deformation temperature. Calculate what this range is so that you can find a heat deformation tester with the appropriate temperatures to perform your testing successfully. If you have questions about how to select the correct equipment for your heat testing, Please feel free to contact us. Thanks.
