About M20
A machinist’s precision. A racer’s perspective.
M20 Machine and Fabrication is led by Matt Obertanec—owner, operator, programmer, fabricator, and racer. That combination matters. Parts are considered as pieces of a complete system, not isolated objects on a print.
Motorsports is a proving ground, not a limitation. M20 brings 20 years of mold experience, extensive mold-design capabilities, and CNC capacity spanning prototypes, custom one-offs, small runs, and full production work.
