This machine assembles the stainless steel cap to the steel nut and crimps the two together. The machines are completely automated, using a Merrill Engineering & Integration RP chassis as the heart of the system. The RP machine is an all mechanical driven assembly system.
All of the parts are fed into the machine from vibratory feeders. There are multiple feeders that allow the switching from one type of nut to another, electrically.
The machine produces 2250 pieces per hour (1.6 seconds per part)
The customer has multiple machines, the earliest of which has produced over 250 million parts without any major downtime problems.
