INDUSTRIES
Industrial Equipment & Robotics Parts
Industrial buyers do not judge you on the prettiest part. They judge you on whether batch ten assembles like batch one, whether a replacement shaft ordered two years later still fits, and whether anyone answers when a line is waiting.
HAFO Mould machines industrial and automation parts in its own Dongguan factory — turning, milling and mill-turn in one shop, inspection on automatic CMMs, material certificates so you can prove what a part is made of.
Same factory since 2007
Repeat orders are most of the work.

Making parts since 2007
Parts We Machine for Industrial Equipment and Robotics
Fittings and connectors
threaded fittings, adapters, couplings and fluid connectors in stainless 303/304/316 and brass, metric and imperial threads
Brackets and frames
machine brackets, sensor mounts, robot-arm links and structural plates in aluminum 6061/7075/6082
Manifolds and valve bodies
milled manifolds with cross-drilled galleries, valve blocks and pump housings where internal passages and sealing faces must agree
Automation components
gripper fingers and jaws, end-effector parts, guide rails' plates, fixture and jig components, change parts for packaging and assembly lines
Wear and sliding parts
bushings, guides and wear plates in POM, UHMW, PEEK and bronze-adjacent metals, machined or, at volume, molded
The Problems We Solve for Industrial Buyers
A part that is two parts.
Turn it, mill it, cross-drill it — in most supply chains that is three queues at three shops, and every hand-off adds stack-up and delay.
A part that is two parts.2
A part that is two parts. (continued)
Our turned and milled work stays in one factory, mill-turn parts included, finished in coordinated setups. Features locate to each other the way the drawing intends.
Repeatability across batches.
Industrial parts get reordered for years. We inspect against the drawing on automatic CMMs and can supply dimensional and CMM reports per batch on request. Batch ten gets checked against the same standard as batch one — and if a dimension drifts, the report catches it before your assembly does.
The wrong stainless grade in the wrong environment.
A 303 fitting in a washdown line is a corrosion claim waiting to happen. Material certificates come with your order, and the free DFM review includes a grade sanity check: 303 for economical turned parts in mild service, 304 as the all-rounder, 316 where chlorides, washdown or marine air are present
Threads that do not gauge.
Fittings fail at the thread more than anywhere else. We machine and tap metric and imperial threads, internal and external, and gauge to the standard on your drawing. Specify it; the DFM review confirms it before production.
"Precision everywhere" pricing.
Tolerance every dimension tightly and every dimension gets slow — and expensive. We hold ±0.025 mm (±0.001 in) where you mark it (bearing seats, sealing faces, locating bores) and standard ISO 2768-mK ±0.13 mm elsewhere.

Processes and Materials
Turning, milling and mill-turn
across 69 machining centers; maximum CNC travel 800 mm (31.5 in). Wire EDM and EDM in-house for keyways, slots and sharp internal features.
Metals
stainless 303/304/316, carbon steel 1018/1045, alloy steel 4140, aluminum 6061/7075/6063/6082, brass, copper, titanium, magnesium.
Engineering plastics
POM for gears and precision sliding parts, UHMW for wear strips and guides, PEEK for hot or chemically aggressive service, PA, PC, ABS, PTFE — machined to plastic tolerance levels (±0.25 mm standard, ±0.05 mm precision on suitable dimensions).
Finishes
passivation (recommended after stainless machining), polishing, brushing, bead blasting, black oxide, electroless nickel and other plating, anodizing and hardcoat for aluminum.
When volume grows
parts that start as machined components can move into tooling and molding in the same building, keeping the supplier — and the inspection standard — unchanged.
Design Notes That Save Machine Time on Industrial Parts
The tolerance review catches something else, too: the small design details that quietly add an operation. We raise the same ones again and again on industrial drawings. Deep, small-diameter holes that need special tooling, where a through-hole plus a plug would do the same job.
Internal corners drawn sharp, where a standard cutter radius changes nothing functionally
Three near-identical thread sizes on one assembly that could be one size — fewer tool changes, fewer gauging errors. Cosmetic finishes on faces nobody will ever see.
None of it changes how the part works
All of it changes what it costs, every batch, for as long as you order it — which can be years. The notes come back with your quote, inside 24 hours. The choices stay yours.
TOLERANCES AND QUALITY CONTROL
Default is ISO 2768-mK
Precision dimensions are held to ±0.025 mm (±0.001 in) on marked features; our guide CNC Machining Tolerances Explained: Standard vs. Precision sets out the logic in full.
Inspection runs on 3 fully automatic CMMs
Documentation available on request: CMM reports, dimensional reports, material certificates, finish certificates, FAI reports, and pre-shipment photos or video.
For spares and repeat orders, tell us the critical dimensions once
they are the ones measured and reported on every batch.
HAFO is ISO 9001:2015 certified
