PEEK Injection Molding Part

PEEK, or polyetheretherketone, is a high-performance thermoplastic known for its outstanding strength and ductility. 

It offers several key benefits that make it a versatile material for various applications:

1. Good Strength and Stiffness: PEEK exhibits exceptional mechanical properties, including high tensile strength and stiffness, making it suitable for applications requiring robust and load-bearing components.

2. High Ductility: Despite its strength, PEEK also maintains a high level of ductility, allowing it to withstand deformation without fracturing, making it resilient and durable.

3. Chemically Resistant: PEEK is highly resistant to a wide range of chemicals, including solvents, acids, and bases, making it suitable for use in challenging environments where chemical exposure is a concern.

4. Food Safe: PEEK is compliant with FDA regulations for food contact, ensuring its safety for use in food processing and packaging applications.

5. Sterilizable for Medical Applications: PEEK can be sterilized using various methods, such as steam, gamma radiation, or ethylene oxide, making it suitable for medical and healthcare applications where sterility is critical.

Overall, PEEK's combination of strength, ductility, chemical resistance, and food safety compliance makes it a popular choice in industries such as aerospace, automotive, medical, and food processing, among others.

For molding PEEK parts, the following parameters are recommended:

1. Drying temperature/time: Pre-drying the PEEK material is crucial to ensure proper molding. It is typically dried at 150°C for 3 hours or at 120°C for 5 hours to remove any moisture from the material.

2. Gate: The gate size should be larger than 1mm or at least 0.5 times the thickness of the part. A suitable gate design helps facilitate the flow of molten PEEK into the mold cavity.

3. Mold Shrinkage: The mold shrinkage for PEEK parts is typically around 1% (ISO 294-4). Understanding the mold shrinkage is essential for determining the appropriate dimensions of the mold cavity to achieve the desired final part dimensions.

By adhering to these molding parameters, you can produce high-quality PEEK parts with the desired mechanical properties and dimensional accuracy. It is important to note that specific molding conditions may vary based on the type and grade of PEEK material used, so it is always recommended to refer to the material supplier's guidelines and conduct proper testing and optimization for your specific application.
