What is PEEK?
Polyetheretherketone (PEEK) is a reinforced thermoplastic polymer with relatively high temperature resistance and good processability. Peek retains its function, albeit with reduced efficiency, at temperatures up to 500°F (260°C) and above. This is because Peek maintains its mechanical properties and chemical composition unchanged within its enclosed environment.
Furthermore, this material can be produced in various forms, including sheets, rods, tubes, granules, and filaments. In addition to unfilled peek, it can be reinforced by adding 30% glass fiber or 30% carbon fiber to create reinforced products. Glass fiber reinforced peek exhibits significant properties, including high durability, high stiffness, and high strength, and maintains dimensional stability even in harsh thermal and chemical environments due to the addition of glass fiber. Polyether ether ketone (PEEK) is a colorless, organic, crystalline thermoplastic polymer belonging to the polyarylether ether ketone (PAEK) family, and is widely used in engineering fields.
PEEK CNC Machining Materials
Whether manufacturing complex geometries or meeting stringent industry standards, Peek ensures reliable performance and durability in harsh environments. Below are some commonly used peek materials we offer.
General Purpose PEEK

Our Unique PEEK CNC Machining Capabilities
Elimold not only processes peek finished parts from various materials such as sheet, bar, and tube, but also leverages our strong machining capabilities to fully utilize the synergistic effects of various manufacturing processes. Unlike traditional methods of producing complex geometries using semi-finished products, which result in significant material waste, combining injection molding and machining is a viable option. Therefore, we can perform final finishing on near-net-shape peek preforms from injection molding to achieve the final geometry required by our customers. Furthermore, we can also perform post-processing on custom peek profiles and tubes.
PEEK CNC Machining Tolerances
Our machining processes achieve tight tolerances (±0.01mm) and smooth surface finishes to meet functional and aesthetic requirements. For most plastics, our standard machining tolerance is ±0.03 mm (±0.0012 inches). For stable engineering plastics such as PEEK, POM, and G-10, we can achieve even tighter tolerances depending on the part geometry. Critical dimensions should be clearly indicated on your technical drawings. With advanced 5-axis and multi-axis machining technology, we are able to efficiently and reliably produce complex geometries of unfilled, glass fiber, and carbon fiber reinforced peek.

Surface Finishing Options for PEEK CNC Parts
As Machined
PEEK can be left as-machined, providing a natural surface finish with minimal processing.
Sand Blasting
This can be used to create a matte texture on PEEK surfaces for enhanced appearance or grip.
Tumbling
Useful for smoothing edges and creating a more uniform finish on PEEK parts.
Teflon Coating
Applying a Teflon coating to PEEK can improve its wear resistance and reduce friction.
Painting
PEEK can be painted for aesthetic purposes or to provide an additional layer of protection.
Powder Coating
While less common, powder coating can be applied to PEEK for added durability and a variety of colors.

Other PEEK Plastic Parts Manufacturing Services
PEEK materials can be processed not only through cnc machining but also through additive manufacturing or injection molding. The specific process chosen depends on the requirements of the final product and time and budget constraints. For 3D printing, peek materials are available in FFF filaments and SLS powder.
However, the application of peek materials in cnc machining and injection molding still far exceeds that in additive manufacturing. Because 3D printing can easily achieve complex (partially hollow) geometries, it is becoming increasingly popular in the field of printing biocompatible medical implants.
FAQ
Because PEEK is a high-performance material, some difficulties may arise during machining. Metals dissipate heat better than plastics; therefore, excessive heat buildup in the workpiece can not only alter certain properties of PEEK but may even cause deviations in dimensional or shape requirements. To machine this material while maintaining high tolerances and achieving a fine surface finish, specialized carbide cutting tools, along with the correct coolant and other appropriate machining parameters, are required.
For CNC-machined PEEK parts, annealing is a necessary step to eliminate internal stress and improve the material's dimensional stability. The annealing temperature for these parts depends on their melting point, so they need to be gradually heated to a specific temperature, held for a period of time, and then slowly cooled. This method ensures that all dimensions meet requirements, prevents part deformation, and avoids exceeding the tolerances allowed by the drawings.
Besides part geometry, tolerances, and intended application conditions, factors affecting the final machined part, such as temperature and chemicals, must be considered when designing PEEK machined parts.
In my experience, Delrin is easier to machine due to its lower hardness and better chip removal. However, PEEK's superior heat resistance (up to 260°C) and chemical resistance make it more suitable for high-performance or harsh environmental applications.
Compared to polyoxymethylene (POM), polyetheretherketone (PEEK) offers higher temperature resistance, superior chemical resistance, and greater mechanical strength. POM is cheaper but lacks the high-performance characteristics of PEEK. POM is suitable for general applications, while PEEK is better suited for harsh environments with extremely high durability and reliability requirements.
PEEK CNC parts can have wall thicknesses as thin as 0.0008 inches with tolerances of 0.0002 inches. PEEK-machined parts retain their functionality, but strength will be reduced due to softening within this range.
Yes, PEEK is resistant to almost all chemicals except concentrated sulfuric acid. However, incompletely crystallized PEEK may experience stress cracking in solvents such as acetone.
PEEK, like other high-performance engineering thermoplastics such as PEI, PPS, PAI, and PSU, offers high temperature resistance, chemical resistance, and excellent mechanical and electrical properties. These materials are widely used in high-strength applications in the aerospace, automotive, and electrical industries. Due to their similar properties, other alternative materials may be considered depending on the specific application.
PEEK and PTFE are not the same. PEEK is a thermoplastic polymer with excellent chemical resistance, high strength, and low weight. Polytetrafluoroethylene (PTFE) is a fluoropolymer with properties such as chemical resistance, extreme temperature resistance, and abrasion resistance. Both materials have their advantages and disadvantages in CNC machining services.
PEEK plastic machining services offer numerous advantages, including high precision, high accuracy, excellent mechanical properties, and resistance to extreme temperatures and chemicals. PEEK materials are renowned for their strength and durability, making them ideal for industries such as aerospace, medical devices, and automotive engineering. CNC machining can easily create complex shapes and designs, ensuring the final product meets the required precise specifications.
