Frequently Asked Questions (FAQs)

What materials can China CNC manufacturing factories process?

China CNC manufacturing factories can process a wide range of materials, including aluminum (e.g., AL 6061-T6, 6063, 7075), stainless steel (e.g., 303, 304, 316L), copper, iron (e.g., 4140, Q235), titanium, and various plastics like PEEK, Nylon, and PMMA. This versatility allows you to choose the best material for your specific application.

How long does it take to receive CNC machined parts from China?

The delivery time for CNC machined parts from China varies depending on the production stage. For samples, you can expect delivery within 24 hours to a few days after payment. For mass production, it typically takes around 20-25 days after receiving the deposit. The exact time can vary based on the complexity of the parts and the quantity ordered.

What kind of surface treatments are available for CNC machined parts?

You can customize the surface treatment of your CNC machined parts according to your requirements. Common surface treatments include anodizing, electroplating, PVD, nickel plating, sandblasting, powder spraying, polishing, multi-color anodizing, and spray painting. This ensures your parts meet both functional and aesthetic needs.

How do I ensure the quality and accuracy of CNC machined parts from China?

To ensure quality and accuracy, it’s crucial to work with a factory that has robust quality control measures in place. Look for factories with ISO9001 certification and advanced inspection equipment like 2D and 3D coordinate measuring machines. Additionally, a factory that requires a prototype or sample before mass production can help verify the performance and accuracy of the parts.

What are the key considerations for shipping and customs when importing CNC parts from China?

When importing CNC parts from China, you need to navigate both Chinese export regulations and import regulations in your destination country. Ensure you have proper documentation such as commercial invoices and packing lists. Understanding export duties, taxes, and any necessary licenses is essential to avoid delays and penalties. Working with a freight forwarder or customs broker can also simplify the process.
