Average Fuel Economy (CAFE) Standards are becoming more stringent every year requiring
a constant drive to improve fuel economy any way possible. Among the most popular ways of improving fuel
economy is weight reduction.
How can extruding
and tapping lead to weight reduction?
When
a threaded hole is required in stamped parts the two most common processes are
extruding & tapping and adding weld nuts. Anytime something is added to a
part weight is added. While the minute
weight of one weld nut may seem insignificant, add up all weld nuts throughout
a vehicle the sum total can become a real weight savings.
There
are factors to consider when looking at extruded/tapped
holes v. weld nuts
including number of threads required and pull test requirements. If a weld nut is not spec’d as necessary then
extrusion & tapping is the best alternative for reducing the weight of a
part.
Of
course, the most economical way of tapping extruded holes in stamped parts is In-die
Tapping. Hutchison Tool Sales is the
in-die tapping industry expert and welcomes the opportunity to collaborate with
