Manufacture a Product in China

Transition from Prototype to Production

When you want to manufacture a product in China, you must move from making a prototype to making many products. First, check if your prototype works well and meets your design needs. Work with your supplier to plan the best way to make your product. Here are some steps you should follow:

1. Make sure your supplier agrees your prototype is ready.

2. Plan how to make your product, including tools and parts.

3. Do a small test run before making lots of products to find problems.

4. Check if your supplier’s quality control is good.

5. Watch your supply chain so you always have the right materials.

6. Use feedback and new technology to keep getting better.

There are two main ways to manufacture a product in China. In the Western way, you control the design and pay for tools and parts. This gives you more control but costs more money. In the Chinese way, your supplier does most of the work. This is faster but you have less control. Always plan with your supplier and check the quality often.

Tip: Always do a test run before making lots of products. This helps you find problems early and saves money.

Certifications & Compliance

You need certifications when you manufacture a product in China. You must follow Chinese and international rules. The CCC mark is the most common certification.

Callout: A strong supply chain and a good assembly plan help you make your product in China with fewer problems.

Common Pitfalls

Miscommunication

Miscommunication is a big problem in rapid prototyping in China. Sometimes, your supplier says "yes" but does not really understand you. In China, "yes" can mean "I hear you," not "I agree." This can cause mistakes in your project. You may think your supplier will follow your plan, but they might have questions they do not ask.

• Chinese suppliers may not ask questions because they want to show respect.

• They might see you as a "boss," so they do not talk openly.

• In China, friendship and casual talks are more important than contracts.

• Saying things in different ways helps everyone understand better.

• Visiting the factory shows you care and helps build trust.

Tip: Ask your supplier to repeat your instructions. Use pictures and easy words to explain what you want.

Incomplete Files

If your files are not complete, your project can be delayed. When you send files with missing details, your supplier cannot start making your prototype. Problems like missing drawings or files that do not open can stop the process.

• If files are missing or not clear, there can be errors in PCB work.

• If your files do not match, your supplier must wait for your answer.

• These problems make it hard to get prices and pick a factory.

• Write down any problems you know about to avoid mistakes.

• Make sure assembly drawings are clear and approved before starting.

Note: Always check your files before sending them. Clear files help your project move faster.

Rushing the Process

If you rush rapid prototyping in China, you can make mistakes. Skipping steps or testing too fast means you might miss something important.
