Machining notes
PEEK is typically used when cheaper plastics cannot meet the application requirements.
The material cost is higher, so part geometry and quantity should be evaluated with care.
Tolerance expectations should reflect both function and the value of the material itself.

FAQ
Common questions about this CNC material.
Why machine PEEK instead of a standard plastic?
PEEK is often chosen because it offers much higher performance in temperature, chemical resistance, and mechanical stability than standard plastics.
Is PEEK expensive?
Yes. PEEK is a premium engineering plastic, so teams usually choose it when the application requirements clearly justify the added cost.
What industries use machined PEEK parts?
Medical, laboratory, electronics, aerospace, and advanced industrial sectors often use PEEK when high-performance plastics are needed.
