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 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.

Practical feedback from engineering and procurement teams who rely on PiPrecision for custom CNC parts
“PiPrecision helped us move a complex aluminum fixture from prototype to repeat production without tolerance drift. Their inspection reports were clear, and the parts arrived ready for assembly.”
“We needed a small batch of stainless housings with tight cosmetic requirements. The team flagged a machining risk early, suggested a cleaner setup, and still held our delivery date.”
“I've been in the business for 20+ years and rarely find a CNC machining supplier who can match this level of precision with competitive pricing. Highly recommended.”
