Ultem PEI machining parts

Ultem PEI machining parts


Ultem PEI machining parts description

For machined parts requiring added strength, engineers turn to Ultem®. This high-performance thermoplastic is considered one of the best for exhibiting excellent strength and stiffness. Ultem® also maintains great dimensional stability at high temperatures (200°C).


Engineers turn to this material when they need parts machined for demanding applications in the Aerospace industry for aircraft and spacecraft and in Medical industry applications requiring repeated sterilization cycles.


As is the case with many high-performing plastics, understanding the machining characteristics of Ultem® is critical to producing a precision part. Many companies machine Ultem, but it’s critical to work with one that knows how to manage stresses in the material to achieve complex tight tolerance parts.

  • Multi-axis machining helps us achieve precise tolerances and ensures your parts are machined correctly the first time with minimal handling and fixturing. Often, even the most complex parts are completed in a single operation.
  • Digital Product Definition (DPD/MBD) processes allow us to machine complex Ultem® parts directly from your CAD models. Working directly from CAD models reduces errors and improves accuracy, resulting in decreased costs for your project.
  • First-rate communication is a top priority. You’ll have a single point of contact throughout the entire project, giving you constant updates as your project moves forward.


Q: Are you trading company or manufacturer?
A: We are professional PTFE product manufacturer with ISO9001, ISO14001 certificated, and all material are RoHS, Food grade.

Q: Can you provide free samples?
A: Sorry, Free samples are not available for the custom parts. But after you place the order, samples cost would be return. Which is "FREE" in some way.

Q: I have a drawing, can you produce?
A: First, please send your drawing to our sales representative, they will forward all the information to our engineer and evaluate our capacity, a detail proposal will be reply with 24 hours.

Q: I have a PTFE sample but don't have drawing, what can i do?
A: In this situation, firstly please send us some photos of your sample, we will evaluate. If our factory can produce, then secondly we will ask sample from you, the Draftsman will make drawings according your sample, PS: Make sure your sample is new and unused.
