Precision, engineered as a promise.
HAO Mechatronics began in Rajkot with a single CNC cell and a stubborn conviction: a tolerance is not a target, it is a commitment. Two decades on, that conviction runs three integrated divisions — machining, investment casting and precision fasteners — under one quality system.
We build hardware for people who cannot afford surprises: automotive production lines, flight-critical aerospace assemblies, defense programs with full traceability, and marine systems that live in salt water. The work is different every day. The discipline never changes.

Our values
Tolerance is a Promise
A number on a drawing is a commitment. We measure everything and guess nothing.
Traceability by Default
Material certs, process records and inspection data follow every lot we ship.
One Roof, One Owner
Machining, casting and fasteners under one system means fewer handoffs, fewer surprises.
Engineered Up Front
We solve the hard problems in DFM and simulation, before we cut metal.
