Universal impact tester has firmly placed its importance in the testing of various materials and components. The results help in determining the resilience (the amount of energy absorbed in impact by a material over a unit of volume) of the sample. The results supplied by the machines are given in joules per cubic meter.
In most cases, the tests are performed on metal; in a few cases, the sample can be plastic or similar items that exhibit elasticity and deformation, when pressure is applied. They are used in addition to the melt flow test, to confirm the quality of the sample.
The impact test is mainly designed using the physics concept. The equipment consists of a pendulum striking arm that is raised to a certain height and then dropped onto the sample. This action would exposé the testing sample to maximum momentum and kinetic energy. The hammer then again swings in the opposite direction and maximum height, so that the sample will be exposed again to a certain amount of force. The potential height and speed would help in calculating the pressure experienced by the sample.
These machines would need careful professional installation. The user would require a platform that is at least forty times stronger than the impact hammer; hence concrete could be the best option. The bases provide the required stabilisation for the machine and mostly embedded into the floor. In very rare cases, the base lies above the floor.
A few manufacturers provide the machine with a set of metal rails that can be placed under the platform for maximum support. The levelling screw helps in maintaining a flat surface. If you wish you use a forklift to move the machine and its setup from one place to another. To make maximum use of the machines, one can ask for various accessories that can be bought from the equipment supplier.
