01 / Why choose this material
Properties and uses
of PEEK.
High-performance thermoplastic for parts subjected to heat, load, and chemical agents. It offers good stability and mechanical resistance in demanding conditions.
PEEK, polyetheretherketone, is a thermoplastic used in parts subjected to demanding conditions. Its selection must meet a specific need for temperature, chemical resistance, or wear. The unreinforced grade and filled compounds have different properties.

Applications of PEEK
Insulators and connectors
Insulators and connectors in grades without conductive loads.
Process components
Process components with compatible chemical agents.
High-temperature equipment parts
Parts for equipment requiring elevated temperature stability.
02 / A choice based on usage
Choose PEEK
according to your part.
These criteria help define the material, geometry, and working conditions before manufacturing.
01
Temperature and load
The continuous use reference does not replace stress verification, exposure time, and geometry.
02
Wear and friction
Specify speed, lubrication, and contact surface for bearings and gears.
03
Grade and documentation
Indicate reinforcements, certifications, or contact requirements. An industrial grade is not equivalent to a validated medical grade.
The part's function is the starting point.
Indicate loads, temperature, environment, and appearance needed. If the drawing requires a specific grade, include it in the request.
03 / Finishing also counts
Finishes and appearance
of PEEK.
Material and process define the surface. These are the key factors for specifying your part's appearance.
Machining finish
The part retains machining marks. Indicate adjustment surfaces and visible faces on the drawing.
Geometry and surfaces
For functional surfaces, define roughness and tolerances in the drawing. Feasibility is reviewed based on grade and geometry.
Your part requirements
Include the expected appearance and usage conditions in your request to confirm the quote.
04 / From design to quote
CNC machining
of PEEK.
Milling and turning allow manufacturing PEEK parts from a block, plate, or bar. The tool removes material to obtain faces, cavities, drilled holes, and contours according to the design.
Send a 3D model per part in STEP or a native supported format: SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, or 3DM. Attach a PDF drawing for threads, inserts, or specific tolerances. STL is accepted only for 3D printing.
Upload your file and request a quotePart tolerances
For dimensions without a specific tolerance, Proto&Go! applies ISO 2768-m. With a drawing, equivalent tolerances to IT11 can be assessed, depending on the geometry and requested dimensions. Attach the drawing and mark the functional surfaces.
Calculate a tolerance ↗Quantity and cost per part
In CNC, setup costs are distributed across the batch units. The final reduction depends on machining time and material.

Frequently asked questions
Before manufacturing
in PEEK.
Properties, applications, and manufacturing: answers to prepare your request.
What is PEEK and what are its properties?
High-performance thermoplastic for parts subjected to heat, load, and chemical agents. It offers good stability and mechanical resistance under demanding conditions. Reference tensile strength, modulus, and elongation for natural TECAPEEK without reinforcement. Density and continuous use are indicative based on the catalog. Admissible temperature depends on load and duration; medical contact requires a specific grade and validation.
What parts can be machined in PEEK?
We can manufacture bearings and gears, insulators and connectors, process components, and high-temperature equipment parts. CNC machining allows adapting the geometry to your 3D file. Define the loads, the environment, and the finish so we can review the application.
When does it make sense to choose PEEK for a machined part?
When the service requires a combination of heat, chemical resistance, and load that other plastics in the catalog do not cover. It is advisable to define those requirements before assuming its higher cost. For less demanding applications, compare options like POM or PET.
Can PEEK always work at 250 °C?
250 °C is a reference for continuous use of certain grades, not a guarantee for any part and load. Duration, stresses, environment, and supply grade must be checked for the specific design.
Can any machined PEEK be used for a medical implant?
No. A medical application requires an identified grade and the corresponding validations for the intended use. The resistance of industrial PEEK does not imply biocompatibility nor authorization for implants. Indicate those requirements before requesting the material.
How much does it cost to machine a PEEK part?
The price to machine PEEK depends on the geometry, grade, tolerances, finish, and quantity. It includes material, preparation, and machining. Upload the 3D file to the Proto&Go! platform to receive a quote with cost and lead time.
What tolerances can I request for a PEEK part?
For dimensions without a specific tolerance, Proto&Go! applies ISO 2768-m. With a drawing, equivalent tolerances to IT11 can be assessed, depending on the geometry and requested dimensions. Attach the drawing and mark the functional surfaces.
What file do I need to manufacture a PEEK part?
Send a 3D model per part in STEP or a native supported format: SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, or 3DM. Attach a PDF drawing for threads, inserts, or specific tolerances. STL is accepted only for 3D printing.
