POF film thermal shrinkage performance tester

heating systemThe heating system is the "heat supply station" of the POF film thermal shrinkage performance tester, which shoulders the responsibility of providing precise thermal environment for the POF film. Advanced heating techniques are generally used, such as high-precision resistance wire heating or efficient infrared heating. These heating methods can quickly and uniformly increase the temperature inside the heating chamber, accurately reaching the set temperature value. Moreover, the heating system is equipped with a high-precision temperature controller, like a strict "temperature manager", which can control temperature fluctuations within a very small range. The temperature control accuracy can usually reach ± 0.3 ℃ or even higher, ensuring that the POF film undergoes heat shrinkage testing under stable temperature conditions.

Fixture deviceThe fixture device is like a sturdy "gripper", its function is to firmly clamp the POF film sample, keeping it in a fixed position and shape during the testing process, and not being disturbed by external forces. The design of the fixture fully considers the characteristics and testing requirements of the POF film, using special materials and structures to ensure sufficient clamping force on the POF film, prevent it from slipping during the heat shrinkage process, and not cause damage to the POF film, ensuring the accuracy of the test results.

Data Collection and Analysis SystemThe data acquisition and analysis system is the "smart brain" of the tester, responsible for collecting, processing, and analyzing data from force and displacement sensors. This system usually consists of high-performance computers and professional testing software. Computers quickly receive electrical signals from sensors and convert them into intuitive numerical and graphical forms. Professional software conducts in-depth analysis of data based on preset algorithms, which can not only calculate key performance indicators such as thermal shrinkage rate and thermal shrinkage force, but also generate detailed test reports, providing users with comprehensive and accurate evaluation of POF film thermal shrinkage performance.
