Scope of Application:
This testing machine is suitable for evaluating the dynamic impact resistance of basketballs, footballs, volleyballs, and handballs. It uses two high-speed rotating drum wheels positioned opposite each other. Under the combined action of friction and compression, the test specimen is propelled at high speed to impact a rebound plate. The rebound plate then returns the specimen into a receiving funnel, from which it is guided by gravity back to the launching drum wheels to be projected again.After a preset number of test cycles, the specimen is inspected for changes in internal pressure and for any defects such as rupture, internal explosion, peeling, debonding, yarn breakage, or deformation.
