4. Product Features:
A) Apply continuous automation production.
B) Double composite riveting efficiently save precious metals and reduce the cost
C) Trimetal rivet can replace solid rivets. It widely used as moving contacts during two sides of contact, to a great extent reduce the material cost.
D) Improve the contact rivet riveting performance.
5. characteristics:
1, There are two kind of composite methods in Contact Rivet :head layer can use Ag ,Cu ,Pd,Pt
and its alloy materials ; base material generally chooses pure copper which has better formation and electricity conductivity ,precious metal materials are only compounded at essential contact position of Electrical Contacts so that they can economize precious metal,reduce the cost of Electrical Contacts and benefits the development of society.
2, It is much easier to choose layer alloy material than monometal contact rivet .Although precious metal alloy materials has excellent electrical contact function ,they are not durable than composite rivets contacts in use .
3, Composite Contact Rivet apply to continuous automatically production .After riveting, they don’t need other manufacturing technical methods (such as electroplating ,welding etc).This method not only simplifies contact manufacturing ,improves efficiency and reduces cost ,but also strengthens the assembling accuracy and credibility of component .
Composite Rivet Contact is mainly used in Automobile ,Home Electrical Appliance ,Relay ,Contactor ,Thermal Controller ,Timer Electronics and Electrical Appliance.
The manufacturing and test equipments which is total amount more 200 sets for making Contact Rivet include Tri-metal rivet machine from Germany ,Bi-compounded rivet machine ,Colored Microscope ,3Dcoordinator Apparatus ,Hardness Test Machine ,etc. We can develop and manufacture them according to customers’ specific requirement ,and the output can surpass one billion pieces annually.
6. Application
Electrical rivets contact are widely used in automobile electric appliances,household appliances,relays,contactors,thermostat,all kinds of switch,aviation appliances,timer and electronic appliances
