Message from Inventor of Desofin , RICHARD H. HAUPT, of Miller & Engelhardt Desofin, Ltd.
I was born in the USA in 1926 and in 1931 I was put to work by my father and his brothers who taught me to hand cast white metals into a light
weight permanent mold. Afterwards, my sister would color these cast toys soldiers with their rifles, cannons and horses and peddle these toys door
to door in our poor neighborhood.
I do not feel sorry for myself that my beginnings were humble and I was only taught good honest work habits by my family.
I discovered three metallurgical grain refiners for brass while working in Germany at Grohe ITT. Two of these were inventions of master alloys
A1MgB and CuPhB and I was paid well by this good employer. The third discovery was in 1982 and this was a powder mixture that only required
200 grams per ton versus six kg/ton for my master alloys. This was called DesofinTM.
My invention of DesofinTM led to success to finally prevent cracks and improve metal fluidity so that the KWC low pressure machine could at last
be successful after many years of failure to do so. The IMR low pressure casting machine was made more versatile and with great improvements
over KWC. Many of the KWC are now in junk yards of the world.
