Brackets and mounting hardware
CNC machined in aluminum or steel: sensor brackets, harness brackets, seat and trim mounting brackets, equipment brackets for vehicle conversions

Automotive Parts Manufacturing
Automotive work rarely fails on an exotic part. It fails on a clip that varies, a housing that warps, a bracket whose holes have drifted since the last batch — and then stops a line that costs far more than the part.
The part has to be identical every time, arrive when it is needed, and come with paperwork that holds up in an audit. HAFO Mould machines and molds automotive-application parts in its own 5,000 m² Dongguan factory:
CNC machining, tooling and injection molding in one building
every batch checked against the drawing before it ships.
We make parts used in automotive applications, and we document them the way automotive quality teams expect: PPAP packages are available on request, alongside CMM reports, dimensional reports, material certificates and First Article Inspection (FAI) reports.
If your program has specific quality-system requirements, raise them in the RFQ — that conversation happens at quote stage, not after parts are made.

Making parts since 2007
Parts We Make for Automotive Applications
022
Housings and covers
machined or molded housings for sensors, control units and lighting-adjacent assemblies, with sealing faces held flat and true
033
Clips, retainers and fasteners
molded clips and trim retainers where release force and fit have to stay consistent from the first part to the last
044
Interior trim components
molded trim parts, covers, bezels and two-color components where appearance is the specification
055
Bumper-related tooling
large injection molds for bumper-class parts, built and finished in our own toolroom, including hand polishing of large cavity surfaces
066
Under-hood non-critical components
covers, caps, ducts, reservoirs' fittings and brackets that live under the hood but are not safety-critical or pressure-critical parts
If a part is safety-critical
braking, steering, structural crash components — we will say so at DFM stage and decline rather than guess. The list above is where we can actually help.
The Problems We Solve for Automotive Buyers
011
Batch-to-batch drift.
A bracket that fits in March and binds in June is usually a process problem, not a material problem. Machined parts run on the same class of equipment batch after batch. Molded parts run from the same tool, in the same shop.
012
Batch-to-batch drift (continued)
We check and report critical dimensions per batch — so if something drifts, you hear about it from Dongguan, not from your line.
023
Warpage in large molded parts.
Wide, flat parts warp when wall thickness and gating are improvised. Here the toolroom and the molding shop are the same factory, so gate design, cooling and part behavior get argued over together at DFM — before steel is cut, not after T1 samples curl.
034
Cosmetic inconsistency on trim.
Interior parts are judged by eye. We build and polish the cavities ourselves and trial them on our own presses. The texture and gloss you approve on samples comes off the same tool, at the same press settings, as production.
045
Documentation gaps.
Quality teams want evidence, not assurances. CMM reports, dimensional reports, material certificates and First Article Inspection (FAI) reports are available with your order on request.
046
Documentation gaps (continued)
Ask at RFQ stage, so they are planned in — not chased afterwards.
057
Tooling you cannot inspect.
A large tool bought through a middleman is hard to audit from another continent. You get progress photos during the build.
058
Tooling you cannot inspect (continued)
We trial the tool on our own presses (90T–470T, including two 360T two-shot machines for two-material parts), then ship trial parts with measurement reports before the tool is released.
Processes and Materials for Automotive Parts
011
CNC machining
for brackets, housings and low-to-medium volume metal parts: aluminum 6061/7075/6082 for weight-sensitive brackets, stainless 303/304/316 and steels 1018/1045/4140 (Stainless Steel CNC Turned & Milled Parts) where strength or corrosion resistance leads.
012
CNC machining (continued)
Maximum CNC travel 800 mm (31.5 in); MOQ 1 piece, so pre-production and service parts are practical.
023
Injection mold tooling
built in-house — single and multi-cavity, family tools, hot-runner tools and large tools for bumper-class parts.
034
Injection molding
on Haitian presses from 90T to 470T, in ABS, PC, PA, PP, POM and other common engineering plastics.
045
Two-shot and overmolding
for trim parts with soft-touch zones, molded-in seals and two-color buttons and covers. (Two-Color & Overmolded Parts)
056
Finishes
anodizing (including hardcoat), bead blasting, painting, powder coating, plating and passivation for metal parts; polished and textured cavity finishes for molded parts.
TOLERANCES AND QUALITY CONTROL
Machined parts run to ISO 2768-mK by default
±0.13 mm (±0.005 in) standard on metal, ±0.025 mm (±0.001 in) on the dimensions you mark as precision — bracket hole patterns, sealing faces and locating features, usually.
Molded parts follow the plastic levels of the same framework
±0.25 mm standard, ±0.05 mm precision on suitable dimensions. We sort this out at DFM, so nobody promises a molded dimension that physics will not hold.
Inspection runs on 3 fully automatic CMMs
HAFO Mould is ISO 9001:2015 certified (scope: Manufacturing of Hardware Molds and Parts). On request you can have PPAP documentation, CMM reports, dimensional reports, material certificates, surface finish certificates, FAI reports, and pre-shipment photos or video of your actual parts.
Mark the critical-to-function dimensions on the drawing
those are the ones measured and reported every batch. Full inspection setup: Quality & Inspection. The equipment behind it: Our Factory & Equipment.
