Our goal was to produce a safe, reliable and totally user friendly induction brass cartridge annealer which would give absolutely repeatable results every time. After three years of R&D we have succeeded.
Of course, that was only half the challenge. What about the science of brass hardness? What is the correct way to get repeatable neck hardness, and for that matter, how do you even measure it? Try finding the hard science to that on the internet, as opposed to "informed” opinion. It didn’t exist. We decided to invest in significant metallurgy research.
