PEEK Material Guide: Grades, Fillers and Drawing Requirements
Choose the PEEK grade before comparing machining quotations. This guide explains what to specify about the stock, fillers, operating environment and inspection; our PEEK machining service page covers manufacturing enquiries.
Comparison and drawing review
Swipe horizontally to read the full table.
| Requirement | What to specify or discuss |
|---|---|
| Unfilled PEEK | Specify the manufacturer, grade, stock form and required color. A polymer family alone does not identify an approved material. |
| Glass-filled or carbon-filled PEEK | Give the filler type and content. Check whether the design depends on direction-specific properties or the condition of the supplied stock. |
| Application-specific grades | Include the approved specification and required supplier documents. Industrial stock is not automatically acceptable for medical, food-contact or other controlled uses. |
| Material alternatives | List which requirements an alternative must meet and obtain design approval before substituting another polymer. |
Start with the environment, not a universal grade
Provide operating temperature and duration, mechanical load, chemicals, electrical requirements and any cleaning cycle. Ask the material producer for data applicable to the exact grade and test conditions. A temperature value from a generic chart cannot by itself establish suitability for an assembled part.
Control the stock and the drawing revision
Request the required material identification, batch documentation and stock condition in the RFQ. Distinguish a resin datasheet from evidence about the semi-finished plate or rod that will be machined. If a named grade is mandatory, clarify availability before accepting a quotation based on a substitute.
Specify inspection for the finished part
Identify mating features, datums, surface finish and measurement conditions. Thin sections, removed stock and workholding need a part-specific plan. State whether dimensions are checked before or after conditioning, cleaning or other processing; we review the achievable result against the drawing.
Compare PEEK with other plastics deliberately
Where the design allows alternatives, quote the same geometry and quantity in each approved grade. Compare required performance, material availability, machining, inspection and delivery together. There is no fixed price multiple that applies to every PEEK part.
Workshop information
Our company presentation records a 7,000 m² facility in Dongguan, 35 CNC machines and 170 employees. Manufacturing, inspection and any required partner processing are reviewed against the drawing and order requirements.
If a certification or specific document is required, identify its scope before quotation.
Company and equipment informationTechnical references
Check references against the applicable material and process conditions. Listing a reference does not imply that we are certified or approved by that organization.
