2. Get a Quick Quote: We review your design and send you an accurate quote within hours.
3. Confirm & Start Production: Once approved, your order goes directly into our CNC machining schedule.
4. Surface Finishing: After machining, we carry out surface treatments such as anodizing, plating, polishing, or coating according to your requirements.
5. Quality Inspection: Every CNC machining part is carefully measured and tested before delivery.
6. Shipping: Prototypes can be shipped within 3-7 days, and mass production within 20-35 days.

At BIE, we go beyond standard CNC machining services. Our in-house facilities include CNC milling, CNC turning, sheet metal fabrication, die casting, plastic injection, and final product assembly. With these capabilities integrated under one roof, we ensure faster production, tighter quality control, and cost efficiency.
Our machining services cover both simple and complex geometries with a wide range of materials such as aluminum, stainless steel, brass, copper, titanium, and various plastics. No matter your design complexity or production volume, BIE delivers consistent precision and quality.

Our advanced CNC machining equipment allows us to achieve high accuracy and repeatability. Tolerances can reach ±0.01mm, and special critical dimensions can be controlled within ±0.005mm. Surface roughness can be maintained between Ra 0.1-3.2, ensuring excellent finish quality for all CNC machining parts.
Each project is handled by experienced engineers who review your drawings, suggest manufacturability improvements, and optimize the process to achieve the best balance between quality, cost, and lead time.

BIE understands how critical the prototype stage is for design verification. Our CNC machining services allow you to quickly produce prototypes using the same materials and manufacturing methods as mass production. This ensures you can test and validate your design accurately.
For small-batch production, CNC machining remains the most efficient and flexible method. For large-scale manufacturing, we analyze product structure, material, and other factors to determine whether CNC machining or molding is more suitable, ensuring economical and efficient mass production.

Quality is at the heart of our machining services. BIE follows strict quality control procedures, from incoming material inspection to final product verification. We implement 100% inspection for every critical dimension using CMM, optical measuring systems, and surface testers.
Each component undergoes multiple inspection stages to guarantee dimensional accuracy, surface finish, and functional performance before delivery.

BIE provides more than 100 types of materials and surface finish options for your CNC machining parts, including anodizing, powder coating, sandblasting, polishing, plating, painting etc. These finishing options enhance durability, corrosion resistance, and appearance to meet your product’s design and environmental requirements.
