What Peoria Automotive Buyers Should Know
Caterpillar-trained machinists excel at heavy, large-format work
leverage this for automotive frame, bracket, and structural castings that smaller shops struggle to fixture.
Peoria's cost of living keeps shop rates competitive versus Chicago and Detroit
compare landed cost including freight for Midwest assembly plant deliveries.
Heavy-equipment machining expertise translates to superior rigidity and chip-load handling on automotive cast iron and steel
use this advantage for powertrain and drivetrain work.
