One partner, end to end
01Precision Machining
Sub-micron tolerances, production-scale throughput
Multi-axis CNC machining for mission-critical components — from prototype cells to high-volume production runs held to aerospace tolerances.
02Investment Casting
Near-net-shape parts in exotic alloys
Lost-wax and precision investment casting for intricate, thin-walled components that would be impractical or wasteful to machine from solid.
03Precision Fasteners
Standard catalogue to fully bespoke micro-hardware
Cold-formed and machined fasteners in aerospace and marine-grade alloys — from stock profiles to custom, print-to-part special hardware.
Industries we serve
Four industries, one standard of tolerance and traceability.
From enquiry
to delivery.
One documented path for every job — so quality is designed in, not inspected on.
- 01
Enquiry
Share drawings, materials and volumes. We scope feasibility and quote fast.
- 02
Design
DFM review, tooling and fixturing design, and a documented process plan.
- 03
Production
Closed-loop CNC, casting and forming with in-process metrology.
- 04
QC
CMM first-article, lot inspection and full material + dimensional reports.
- 05
Delivery
Certified parts, packed and shipped to schedule with lot traceability.
Trusted on the line
HAO held ±0.005 mm across a 12,000-piece titanium run without a single reject. Their first-article discipline is the reason they are now a sole-source line item for us.
Aria Voss
Director of Supply Chain · Meridian Aerospace Systems
The cast super-alloy impellers came back near-net and metallurgically clean. We cut our finish-machining time in half and have not seen a porosity issue since we moved the program to HAO.
DeShawn Mercer
Chief Engineer · Tideline Marine Propulsion
Full lot traceability, torque-tension data on every batch, and delivery dates that actually hold. For defense hardware that is not a nice-to-have — it is the whole contract, and HAO gets it.

Procurement Lead · Vanguard Defense Dynamics

Precision as a promise
From a single CNC cell in Rajkot to three integrated divisions serving four continents, HAO Mechatronics was built on one idea: a number on a drawing is a commitment. We measure everything, and we guess nothing.
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.
