Sponge/foam plastic ball drop rebound tester -7 inch touch screen

Product Name:Falling ball rebound tester

Product Model: PMLQ-500

Display mode: touch screen

Manufacturing standard: (GB/T6670-2008 ISO8307 ASTM D3574 ISO8307) Determination of rebound performance of soft foam polymer material by falling ball method

GBT 10652-2001 Determination of Elasticity of Polymer Porous Elastic Materials

ASTM D3574 Flexible Cellular Materials -- Test Method for Board, Adhesive and Molded Polyurethane foam

1、 Scope and Function of Application:

Purpose: It is suitable for measuring the falling ball springback performance of soft polyurethane foam

Falling ball rebound testerThe instrument automatically calculates the percentage (i.e. rebound rate) of the ratio of the rebound height of the steel ball to the falling height of the steel ball through the steel ball with the specified diameter and mass falling freely on the foam plastic sample at the specified height, and represents the rebound performance of the foam plastic with the rebound rate.

According to the standard testing requirements, each group of samples consists of 3 samples, and each sample is tested three times. The normal value is taken each time, and the average of the three normal values is taken to calculate the rebound height and rebound rate. This instrument automatically records data and judges the normal value, automatically calculates the average rebound height and average rebound rate, and can also set numbers and save data for different batches of samples for easy query and management. It can also print the current test data.

This instrument is controlled by Siemens PLC from Germany and operated in Chinese on a 7-inch touch screen. It has the characteristics of easy operation, reliable performance, and high measurement accuracy. It is a domestic manufacturer of sponge resilience testing instruments.

Selection and Precautions of Ball Drop Rebound Tester

1. The difference between electrically releasing steel balls and manually releasing steel balls:

A: Manual release: The principle of manually releasing a steel ball is to use a magnet on the handle to attract the steel ball, and then separate the handle from the steel ball through artificial external force. This will inevitably cause the steel ball to deviate and rotate during the falling process, resulting in collision and deviation from the center when it comes into contact with the sample. Moreover, due to the different operating forces of each person or the same operator, it will also cause errors in the results and affect the success rate of the test.

B: Electric release: The principle of electric release of steel balls is to fix the steel ball perpendicular to the electromagnet and at the center of the organic glass tube. After the electromagnet loses its magnetism and falls freely after being powered off, it rebounds after coming into contact with the sample, greatly improving the efficiency of the test and the reliability of the data. At the same time, it also meets the requirement stipulated in the standard that the steel ball should not rotate and be in the center position when falling.

2. Advantages of both manual and automatic readings:

The accuracy of automatic measurement is relatively high, but if there are errors in the test results due to operational errors or uneven samples, manual readings can be used for comparison, effectively reducing the probability of errors and making the test data more rigorous.

3. Regarding the requirements for the value of the test results of the sample due to the rebound of the falling ball:

In the standard, the test results are summarized as follows: each group tests 3 samples, each sample tests 3 results, takes values from the 3 results, and calculates the average of the 3 values as the average rebound rate of the sample. However, some manufacturers in the market have failed to understand the requirements of the standard for test results, resulting in unreliable test data. At the same time, customers do not pay enough attention and importance to this issue. We hope to draw your attention to it.
