Our Legacy

It all began over 50 years ago.

With a dream to start a new life in America, my grandfather Karl Schlosser, fresh out of a tool and die apprenticeship in Germany—home to some of the finest tool and die craftsmen to walk the face of the earth—set out on a ship. Karl and my grandmother Thea embarked on a journey that lasted three long weeks. They lived on the boat alongside many others, with mules and chickens, sleeping on the deck until they reached the USA.

After gaining experience at Bazz Houston, the largest stamping house this side of the Mississippi, working as a tool and die engineer, Karl harbored the ambition to start his own venture. Bolstered by the tremendous and tenacious support of his wife Thea, they created Tricoss Inc., the stamping house that started it all.

Buellton is where the first dies sheared the first parts. They quickly garnered an impeccable reputation for quality, pricing, and great lead-times. From Buellton, Tricoss moved to Goleta, then to Carpinteria, and finally to Ventura over 30 years ago. Since then, some things have changed. I bought out Tricoss in 2013, and at that point, it had begun to transform, becoming more geared towards sheet metal, although we still run dies that have 50 years of stamping on them, initialed by my grandfather, father, and now myself.

Now, under the banner of Trupart MFG, we have 6kW fiber lasers, dual beam laser engravers, CNC mill vacuum forming, CNC press brake, all under the same roof my grandfather commanded 20 presses under. I remember those days; at 7:30, it was like a rocket was taking off. We miss him. I sure wish he could see what he inspired.
