Hi,
I'm drawing up some small parts that need to be cold press fit together.
They are made from brass, and the basic diameter of the two faces being pressed together is 7mm (0.275"), mating face length (depth of mate) is
5mm (0.2"). I need to press the parts together when both cold, and I need them to be securely mated. Afterwards they are to be either gold or silver plated. There isn't a great deal of force being applied to them afterwards, but what force there will be will be in extraction direction. I would guess maximum extraction force to be 3 or 4 pounds.Can someone advise me the amount the rod (actually thick walled tube-all relatively speaking of course) needs to be oversize to be the right fit into the hole.
I need electrical contact too, so I won't want to be using any compounds.
Is there a reference website that I could extract this information from in future, so save this post occuring all the time. (I already found loads of similar posts, but none like my application).
thanks
