Most hinge parts are made with progressive stamping dies. The round
parts (pins and rivets) are likely made with cnc screw machines or cam
operated screw machines. The assembly of the parts can range from very
high tech to very low tech. Low tech assembly in China or Mexico is
probably the trend.

Thank you for all the info.

I'm also trying to understand better the differences between the
existing manufacturing process that are used for hinges: stamped,
profiled and forged hinges.

>From what I have found for the moment, is that stamped is the cost
solution. Profiled hinges occupies less space inside the door, but is
slightly heavier than a stamped hinge because profilled hinges are
"filled" with metal, whereas stamped hinges are like metal sheets. Yet
profiled hinges offer better mechanical properties (more resistant) at
a higher cost. Finally, forged hinges are better in all ways, except
for the price, as they are more expensive.

Could any one confirm this, and maybe give me some more information
about the benefits from each technology and maybe give me some numbers
about the gain and loss between each technology (hinge manufacturers
are not really willing to give me those answers)?
Does anybody had the chance to weight such hinges (unfortunately, car
dealers don't have such parts in stock)?

Thank you!
