Industry: automotive and EV subsystems
CNC machined parts for automotive and EV subsystems
Automotive and EV subsystems need production-grade CNC parts in aluminium, steel, and engineering plastics at production volumes with PPAP documentation. Boyang supports prototype-to-production transition for non-safety-critical components, with documented change control and full-batch material traceability.
Boyang supports prototype-to-production transition for non-safety-critical automotive and EV components, including brackets, sensor housings, cooling-system parts, and interior trim supports. Material certificates and dimensional reports are issued per batch. PPAP level 3 documentation is available by arrangement following the AIAG PPAP manual.
Compliance: Boyang does not hold IATF 16949 certification. For Tier-1 automotive customers, parts are supplied under the customer’s IATF 16949 quality agreement. Safety-critical parts (braking, steering, airbag, fuel-system) require the customer’s quality system and are not supplied under Boyang’s ISO 9001 alone.
Typical parts and use cases
| Part type | Typical requirement |
|---|---|
| EV battery enclosure brackets | Aluminium 6061-T6 with Type II anodising; bolt-circle true position ±0.05 mm. |
| Sensor housings (ADAS, BMS, thermal) | Aluminium or engineering plastic; IP-rated sealing faces. |
| Cooling-system manifolds and fittings | Aluminium 6061; internal passages ±0.05 mm; pressure-testable. |
| Interior trim supports | Engineering plastics (PC, PC/ABS, PBT); cosmetic and structural parts. |
| Charging-connector components | Brass, copper, or stainless; precision contact bores. |

Frequently asked questions
Is Boyang IATF 16949 certified?
No. Boyang is ISO 9001:2015 certified. Tier-1 automotive customers typically govern their supply chain under their own IATF 16949 system; Boyang parts are supplied under that quality agreement.
Do you provide PPAP documentation?
PPAP level 3 documentation is available by arrangement per the AIAG PPAP manual. Initial submission typically takes 2–4 weeks depending on part complexity.
What is the typical production-run size?
Production runs of 500–50,000 pieces are routine. Higher volumes (up to 100,000 pieces/year) are supported by arrangement with capacity planning.
Can you machine EV battery brackets?
Yes. Aluminium 6061-T6 and 7075-T6 battery brackets are routine; type II anodising for cosmetic and corrosion-resistance is provided in-line.
Do you supply safety-critical parts (braking, steering, airbag)?
By arrangement only, and under the customer’s IATF 16949 quality system. Boyang’s ISO 9001 alone does not cover safety-critical part acceptance.
