Prison machines
At Prison machines, while plastic prisons fall from the cavity, some detoriating static charge is occuring due to temperature and pressure. This charge will be leading into prisons to stick on machine parts and manufacturing defects. Also in multiple prison machines, due detoriating static charges, prisons may be repelling/attracting each other.
For the solution of the problem, a Puls DC placed on the top side will neutralize the static charges and will provide a regular production.
