Ultem® Plastic Machining

Ultem Machined Parts

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.

 

Why You Should Choose Upland Fab for Ultem® Plastic Machined Parts

Upland Fab has over 50 years of experience machining Ultem® and other high-performing plastics. We have the quality-driven processes, technology, and equipment needed to achieve the right results.

We create machined parts from Ultem® 2300, a 30% glass fiber reinforced grade. Understanding the abrasiveness and stress properties is even more important when working in this material. Upland Fab machines Ultem 2300 regularly, giving us the experience needed to machine your part correctly the first time.

  • 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.

CNC Technologies for Machining Ultem® Parts

Upland Fab employs the use of multi-axis machining when working with Ultem®. This application of technology is critical to ensuring the parts are machined correctly the first time with minimal handling and fixturing. Often times even the most complex parts are completed in a single operation.

Digital Product Definition or DPD/MBD processes allow Upland Fab to machine complex Ultem® parts directly from our customers’ CAD models. Working directly from CAD models lets us reduce errors and improve accuracy, which results in decreased costs for our customers.
