The falling ball springback tester for foamed plastics is an instrument specially designed for measuring the falling ball springback performance of soft polyurethane foams. It can accurately measure the rebound rate of foamed plastic after falling from a certain height of a steel ball with a specified mass and diameter, so as to evaluate its rebound performance.
Wide applicability: Foam plastic falling ball rebound testerIt is suitable for measuring the resilience of flexible polyurethane foam, which is its most basic and core application feature. The instrument can accurately evaluate the resilience of foamed plastics after impact through standardized test methods, and provide reliable data for material quality control and research and development.
High precision testing capability: Foam plastic falling ball rebound testerEquipped with high-precision photoelectric speed measurement device, it can quickly and accurately measure the rebound speed of steel balls and calculate the rebound rate. The measurement accuracy of rebound speed and rebound rate have both reached± 1% ensures the accuracy and reliability of the test results.
Flexible testing parameter settings: Users can set the drop height of the steel ball according to their needs(0~500mm can be set to adapt to different materials and testing requirements. The movement speed of the magnetic suction seat can also be set within the range of 0-25mm/s, making it easy to adjust the impact force and speed during the testing process.
Convenient testing operation: The instrument adopts electromagnetic attraction/Releasing the steel ball ensures its free fall and simplifies the testing process. Equipped with a micro thermal printer, it can print test data in real time, making it convenient for users to record and analyze.
Friendly user interface: The control program of the instrument supports switching between Chinese and English, making it convenient for users with different language backgrounds to use. The program interface is clear and intuitive, providing various functions such as viewing historical test data, setting test methods, and manual debugging, meeting the diverse needs of users.
Stable performance: The instrument uses a stepper motor to drive the steel ball to lift, achieving precise control of the falling height and ensuring the stability and consistency of the testing process. The overall structural design is reasonable, runs smoothly, and can maintain high-precision testing capabilities for a long time.
