5 steps to create a cnc machining parts in China

Let’s take a look at the cnc machining process in China: 

Step 1: Designing Your Product 

This step includes the CAD drawings, PCBA schematics, and other design methods. You can design in-house or get a design firm to provide cnc machining parts concept design. 

It is crucial that you own the blueprints and not your China manufacturer. Otherwise, they will consider it as their intellectual property rights. 

Step 2: Ensuring the doability of the make or buy the materials 

Then, you’ll need to conduct sourcing before making or buying the parts. Ensure to calculate the costs and consider the technical difficulties of cnc machining. 

You should qualify suitable suppliers for the customization of product parts. 

Step 3: Assembling Your cnc machining parts 

You can start the assembly after the preparation of the necessary parts. There are several possible problems you’ll face. For instance, product ergonomics issues, aesthetic issues, performance issues, functionality issues, etc. 

Various amendments and repetitions are often required to solve the main problems. 

Step 4: Preparing Production Tooling 

After approval of your cnc machining parts, you can then order the necessary tooling. For instance, the plastic injection molding and the testing equipment. 

Try making some parts with your tooling and ensure that the result is desirable. 

Step 5: Testing Your Product 

Conduct in-depth testings and at least one pilot run before mass production. For instance, testing the product compliance, performance, key functions, and robustness. 

It is better to discover the issues earlier to save fixing time and costs.
