Success Stories
Real-world examples of how we've helped customers solve their manufacturing challenges

EV Motor Housing Production
Electric Vehicle Startup
An electric vehicle startup needed aluminum motor housings for their new EV platform. PiPrecision developed machining process with specialized fixturing, achieving consistent Cpk > 1.67 on critical dimensions with SPC monitoring, successfully ramping from 50/month prototypes to 5,000/month production with zero PPM defects.

Space Telescope Mirror Mount
Space Systems Integrator
A space systems integrator required an Invar 36 mirror mounting structure for space telescope. PiPrecision delivered precision machining with slow-speed strategies and cryogenic stress relief, achieving <1 ppm/°C CTE stability and 0.5 μm flatness over 300mm, passing thermal vacuum testing and qualifying for space flight.
