CNC Machined Car Parts
High‑Performance CNC Machined Car Parts for Automotive
Our Company:
Bosi Precision is a modern manufacturing service provider located in Dongguan, China, with comprehensive in-house machining capabilities. We are equipped with state-of-the-art CNC machinery and staffed by a skilled professional team. Our core expertise lies in high-precision 3-axis, 4-axis, and 5-axis CNC machining using advanced technologies, while we also offer a broad range of complementary services including 3D printing, die casting, sheet metal fabrication, and injection molding.
Why Choose Us – Our Competitive Advantages
±0.005mm Precision for Demanding Tolerances
Our modern CNC machines consistently hold ±0.005mm tolerances. We verify every dimension with CMM (Coordinate Measuring Machines) and other advanced inspection tools. For critical mating surfaces, grinding achieves ±0.002mm accuracy.
01
50+ Machines – Ample Capacity
We operate 50+ CNC machining centers (including 5‑axis, Swiss‑type lathes, and EDM), plus in‑house assembly lines and a fully equipped metrology lab. Our vertically integrated production ensures full control from raw material to finished assembly.
02
Full Material Range + One‑Stop Finishing
We machine all common metals-aluminum (6061/7075/5052), stainless steel (304/316/303), carbon steel, alloy steel, brass, copper, and titanium-as well as engineering plastics like ABS, POM, PC, PEEK, and Nylon.
We also offer a complete suite of surface treatments: anodizing (clear/black/colors), sandblasting, brushing, polishing, painting, electroplating, and laser engraving.
03
Fast Turnaround – 3 Days Lead Time
Standard delivery is 3 business days (for most parts). We respond to RFQs within 24 hours. Expedited services are available for urgent projects.
04
ISO9001 & AS9100 Certified Quality
We are ISO9001 certified, with select production lines meeting AS9100 aerospace standards. Every part undergoes a rigorous inspection process, and a complete Inspection Report is included with every shipment.
