DuPont impact tester

1、 Product introduction:

The purpose of the plastic DuPont impact testing machine is to place the test piece with the coated surface facing up on the impact site, drop the hammer freely at a certain height, and check the damage and deformation after impact. Used for plastic ceramics, acrylic, glass fiber, etc.

And coating adhesion test< br />

IV. Operation steps of DuPont impact tester:< br />
1. Sample preparation:

  Determine the size of the specimen according to the spacing between the clamps (according to the requirements of the test regulations) l

2. Sample installation of DuPont impact tester:

  Place the specimen in the center of the impact seat l

3. Adjust the required test height according to the test provisions (the height interval is 50mm). Insert the fixing fork into the hole< br />
4. Select the weight, place the weight on the fixed fork, enter the test, take out the fixed fork with force, drop the weight and impact it on the impact head, and the impact head impacts the test piece< br />
