Machined Metal Parts
Factory High Quality Precision Machined Metal Parts
Bosi is a precision CNC machining service provider dedicated to delivering end‑to‑end solutions-from rapid prototyping and low‑volume pilot runs to high‑volume production-for industries including aerospace, medical devices, automotive, electronics, and industrial automation.






Product Features
±0.005mm ultra‑high precision – Ensures perfect part fit, reduces assembly adjustments, and cuts rework costs.
Complex geometry in one setup – 5‑axis machining minimises cumulative errors from multiple fixtures, improving overall dimensional consistency.
Surface finish down to Ra 0.4μm – Enhances aesthetics, lowers friction, and extends component life.
Tight form and position control (flatness, perpendicularity, concentricity ≤0.01mm) – Ensures smooth moving parts, lower vibration, and reduced noise.


One‑stop surface finishing – Anodising, plating, sandblasting etc., all in‑house – you manage one supplier, not many.
Individual packaging with inspection report – Every part is packed separately with a complete report for transparent verification.
Expedited prototyping (24–48 hours) – Fast response for emergency validation, accelerating your project schedule.


Our Advantages
1.50+ advanced CNC machines (including DMG MORI, MAZAK) ensure stable capacity for large orders.
2.Mill‑turn centres handle complex rotational parts in fewer operations, improving accuracy.
3.Swiss‑type automatic lathes excel at small‑diameter precision parts (medical, electronic connectors).
4.In‑house wire EDM and precision grinding deliver mirror finishes and high‑hardness materials
5.24/7 online quoting – Upload your drawing, get a preliminary price and lead time within 2 hours.
FAQ
Q1: What surface finishes and coatings do you offer?
A: We provide anodizing (Type II & III), passivation, electroless nickel plating, zinc plating, powder coating, black oxide, DLC coating, bead blasting, and mirror polishing. Our team can help you select the most suitable finish for your application.
Q2: Do you provide design support or DFM services?
A: Absolutely. Our engineers review your CAD models and offer Design for Manufacturability (DFM) suggestions – such as draft angles, radii, and wall thickness – to improve machinability, reduce cost, and shorten lead times. This feedback is especially valuable for complex machining metal parts.
Q3: Can you ship internationally?
A: Yes, we ship worldwide. We handle all export documentation, custom packaging, and door‑to‑door logistics. Standard shipping terms include EXW, FOB, CIF, and DAP – flexible to your needs.
Q4: What documentation do you provide with each order?
A: Every shipment includes material test reports (MTR), full dimensional inspection reports (CMM), and a certificate of conformance. For automotive or aerospace projects, we can also supply PPAP Level 3 and FAIR (First Article Inspection) reports upon request.
Q5: How do I get a quote?
A: Simply submit your 3D CAD file (STEP, IGES, or SolidWorks) and drawing (PDF) through our website or email. Our team responds with a firm price and lead time within 4 business hours.
