research on car hinges

Hi,

I'm doing a research on car hinges and I'm trying to find some
contacts in the automotive industry that could give me some
informations on those components and about the manufacturing process
that is used to produce the hinges.

If any body had some contacts to share, please let me know.

Or if you have some information to share directly, that would also be
great!

 

You were told on the first crosspost how to look them up yourself.

Oh, was "Do a "google" on "National Automotive Door, Hood, Trunk and
Liftgate Hinge
Museum and Archives"" a serious reply? Or did I miss the reply you
are referring to?

I really don't know and am being serious here.

Sure sounded legit to me....

Also sounds like some kid wanting his homework done for him....

Fair enough, but not to me anyway. Hey kids, y'all want to go to the
hinge museum, or we could stay at home and peruse the hinge archives!
(kids) Yay!!! Hinges!!!

Agreed.

The "kid" has already been calling all major actors of the hinge
industry and been able to map about 90% of the technologies used in
the European Market.

Unfortunately, I cannot afford to go to the US to find it out by
myself.

Further more, it is very difficult to have some contacts on the car
maker side and though I past the last 2 weeks calling to European car
makers, I only reached a couple of people that were able to slightly
help me.

 

A massive cross-posting to groups that are likely to be composed of drivers
of vehicles of various makes and models is likely to prove futile.

I have some really interesting copper-plated steel or iron hinges, that look
as if they might have been plated first, and then forged by hand. Doors in
an 1890s vintage Victorian house in Silverton, CO. It is amazing that a
blacksmith could do.

Fair enough.

You should check out the 4x4 shops as they make aftermarket hinges for
Jeep restoration or just looks. Same for custom car shops for American
car restorations.

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.

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!
