Cushion Material Test by Dynamic Compression Tester

You also need to know about the charactaristic data of cushion material, when you design the package.
This data is often given from cushion material company, but if there are no data, you can obtain it by cushion tester.

This test is held in order to perform dymamic compression to blockish cushion materials.
In concrete terms, we can measure the acceleration and displacement of the weight by dropping the test weight to the top surface of the material.
Then so, from these test parameters, we can find the cushion material charactaristics as "Cushion curve" from these tested parameter.

If the cushin curve and product fragirity as critical acceleration is recognized beforehand, cushion effect of designed package freight will be optimized.
