Significantly Extends Die Life
Both our Field testing of Draw Forming and Stamping confirm that by
increasing the fatigue strength of any cold work tool steel, that the life of a
die is improved by a factor of anywhere from 2-10 times depending on the
application.
One of the most difficult tests to pass is Case
Western's Dip Tank test that they only run on Hot Work steels
(H-13). This steel, which is used in die casting, has tendency to build up
stresses rapidly due to the extremes in operating temperature seen during
production of castings. Once the yield strength of the steel is exceeded,
the die surface starts to exhibit cracking. This cracking, commonly known
in the industry as heat checking, if unattended, will lead to a catastrophic
failure of the tool.
Draw Forming & Stamping tooling, with the exception of Hot Forging
dies, do not see this extreme use yet still can significantly show large life
cycle improvements by the MetaLL
ifeÒ
process. Numerous field tests on
both draw
forming and blanking
tooling confirm this fact.
