Some of our customers in the field have been combining the benefits of our
MetaLLifeÒ
and
ThermaLLifeÒ
processes for several years now. One question we are frequently asked is
"How hard is it to weld and polish after these are applied?"
We recently got our chance to find out. We were asked by a major OEM,
in Milwaukee, to process some used tooling. They have been producing
recreational vehicles for over 100 years.
The test involved a "retired" die that had high cosmetic requirements.
Because of heat checking and cavitation breakout, it could no longer produce
acceptable castings. |
We were asked to apply both of our processes in all the known possible
combinations with no concern for cosmetic requirements. The results
surprised even us.

In short, the die went from being retired, to being put back into normal
production. Polishing the castings after any sequence proved not to be a
problem. Welding was no more difficult than on a ion-nitrided surface.
On our website, you will also find compression curve results on test
coupons that were processed in a similar manner and measured with X-Ray
diffraction.
