Frequently Asked Questions (FAQs)

What types of plastics can be used in CNC machining in Chinese factories?

You can work with a wide range of plastics in Chinese CNC machining factories. Common types include nylon (PA6.6), acetal (POM), polycarbonate (PC), ABS, polypropylene (PP), low-density Polyethylene (LDPE), polyether ether ketone (PEEK), and polystyrene (PS). Each plastic has its own unique properties and applications, so it’s important to choose the right one for your specific needs.

How does CNC machining of plastics differ from other manufacturing methods like injection molding?

CNC machining of plastics offers higher precision and accuracy compared to other methods like injection molding. It is particularly suitable for complex designs and tight tolerances. Unlike injection molding, which requires expensive molds, CNC machining allows for more flexibility and can produce parts with intricate details without the need for extensive tooling.

What are the common challenges faced when CNC machining plastics in China?

When CNC machining plastics, you might encounter challenges such as poor surface finishes, dimensional changes, and deformation from clamping. Plastics can deform or expand during machining, affecting precision tolerances. Additionally, issues like poor chip formation and chip ejection can impact the quality of the final product. To overcome these, it’s crucial to minimize clamping forces and understand the specific behavior of the plastic material being used.

How can you ensure the quality of CNC machined plastic parts from Chinese factories?

To ensure the quality of CNC machined plastic parts, you should work with a reliable and experienced manufacturer. Monitor the machining process, and use quality control measures such as inspecting the parts with measuring tools and inspection equipment. You can also ask for chemical analysis or other verification methods to confirm the material used matches your specifications.

Can Chinese factories source high-quality plastic materials from international brands?

Yes, Chinese factories often have access to high-quality plastic materials from international brands. Many major raw material manufacturers, such as INVISTA, have sales teams and authorized distributors in China. You can verify the material used by asking for invoices, delivery notes, or directly contacting the material supplier for confirmation. This ensures that your product is made from the specified high-quality materials.
