Frequently Asked Questions (FAQs)

Frequently Asked Questions About Machining Metal Factories in China

How is quality controlled in Chinese metal fabrication factories?

Quality control in Chinese metal fabrication factories is a rigorous process. Many factories have a dedicated QA team that conducts sample runs and small batch runs before moving to mass production. They also perform in-process and final quality control checks, and some even send samples for testing in third-party laboratories to ensure the products meet the required standards.

What are the common delivery terms and payment methods used by Chinese metal factories?

Chinese metal factories often offer flexible delivery terms such as FOB, CFR, CIF, EXW, CIP, DDP, and DDU. For payments, they typically accept methods like T/T (Telegraphic Transfer), L/C (Letter of Credit), Western Union, and sometimes even PayPal or cash. It’s important to clarify the specific terms and methods accepted by the factory you are working with.

How do Chinese metal factories protect intellectual property?

Protecting intellectual property is a priority for many Chinese metal factories. They often sign special agreements with clients to ensure confidentiality and may only source components from subcontractors for specific parts, preventing them from gaining a full understanding of the product. This approach helps in maintaining the secrecy of your designs and manufacturing processes.

What is the typical production lead time for metal fabrication in China?

The production lead time can vary, but for initial samples, it usually takes around 5 days. If molds are required, you might need to add an additional 20-40 days. For mass production, expect about 30 days, plus another 30 days for shipping. Factories with good relationships with steel mills can procure raw materials quickly, which helps in reducing the overall lead time.

Can I visit the factory and what should I look for during the visit?

Yes, you can visit the factory, and it’s highly recommended. During your visit, observe the production lines, ask about the experience and background of the middle management and workforce, and check their quality management systems. Also, look at their business and export licenses, and ask for references from other clients. This visit will give you a deeper understanding of the factory’s capabilities and reliability.
