PEEK Injection Molding FAQs

What makes PEEK different from other engineering plastics?

PEEK stands apart from other engineering plastics due to its exceptional combination of properties: extremely high temperature resistance (continuous use up to 260°C), outstanding chemical resistance to most solvents and acids, excellent mechanical strength and stiffness, and superior wear resistance. While other high-performance polymers may excel in one or two areas, PEEK delivers across multiple performance criteria, making it ideal for the most demanding applications.

Is PEEK FDA-approved for medical applications?

Yes, medical-grade PEEK complies with FDA regulations for implantable and non-implantable medical devices. It meets USP Class VI and ISO 10993 biocompatibility standards. At Fecision, we work with certified medical-grade PEEK materials and maintain appropriate quality systems for medical device manufacturing. We can provide full documentation and traceability for medical applications.

What are the typical lead times for PEEK injection molded parts?

Lead times for PEEK injection molded parts typically range from 3-6 weeks for new tooling and 1-3 weeks for production runs with existing tooling. Factors affecting lead time include part complexity, quantity, secondary operations, and quality requirements. For urgent projects, we offer expedited services. Contact us for a specific timeline based on your project requirements.

How does the cost of PEEK compare to other materials?

PEEK is more expensive than standard engineering plastics, with raw material costs typically 5-10 times higher than materials like nylon or polycarbonate. However, when considering total lifecycle costs, PEEK often provides better value through longer service life, reduced maintenance, and the ability to replace more expensive metals in many applications. Our engineering team can help evaluate the cost-benefit analysis for your specific application.

Can PEEK be used in high-pressure and high-temperature environments?

Yes, PEEK excels in high-pressure and high-temperature environments, maintaining its mechanical properties at continuous temperatures up to 260°C (500°F) and in pressures exceeding 20,000 psi in some applications. This makes it ideal for oil and gas, aerospace, and automotive applications where other polymers would fail. The specific pressure rating depends on the part geometry, wall thickness, and grade of PEEK used.
