Then by two times upsetting process, the two kinds of metal become the composite contacts. Finally, the products retreat from the mould and enter into the finished product box.
The machine can produce cold heading solid and bi-metal rivet contacts:Typical alloys include:
*Silver
*Fine grained silver
*Silver-Nickel
*Silver-Iron
*Silver-Graphite
*Silver-Cadmium Oxide
*Silver-Tin Oxide
*Gold
*Platinum
*Palladium
