Frequently Asked Questions (FAQs)

What makes PEEK a popular choice for CNC machining in China?

PEEK is a favorite among manufacturers in China due to its exceptional mechanical, chemical, and thermal properties. It maintains its flexural and tensile properties even at high temperatures, has strong resistance to heat distortion, and exhibits excellent chemical and radiation resistance. These traits make PEEK ideal for demanding applications in industries like aerospace, automotive, and medical fields.

How do Chinese factories handle the challenges of machining PEEK?

Machining PEEK can be challenging due to its abrasiveness and heat retention. Chinese factories address these issues by using specialized cutting tools such as carbide or polycrystalline diamond (PCD) tools, especially for reinforced PEEK grades. They also employ cooling methods like pressurized air or liquid coolants to prevent heat-related cracks and deformation. Additionally, annealing the PEEK material before machining helps reduce internal stresses and surface cracks.

What are the common grades of PEEK used in Chinese CNC machining services?

You’ll typically find two common grades of PEEK used in Chinese CNC machining: industrial-grade and medical-grade. Industrial-grade PEEK is strong, abrasion-resistant, and often reinforced with carbon fiber for added strength. Medical-grade PEEK is biocompatible and meets stringent standards for use in medical and pharmaceutical applications. Each grade is selected based on the specific requirements of the end product.

Can PEEK be machined to tight tolerances and complex geometries?

Yes, PEEK can be machined to very tight tolerances and complex geometries. Chinese CNC machining services use advanced machinery and techniques such as 3, 4, and 5-axis CNC milling and turning to achieve precise results. This capability makes PEEK suitable for high-precision industries where intricate designs and tight tolerances are crucial.

How do Chinese factories ensure the quality and biocompatibility of machined PEEK parts?

Chinese factories ensure the quality and biocompatibility of machined PEEK parts through stringent quality control measures. They use protective gloves and keep machined parts in closed containers to prevent contamination, especially for medical-grade PEEK. Each part is inspected by qualified professionals before delivery, and the machining processes comply with international standards such as RoHS, MIL specifications, and AMS standards.
