Ultem® Machining

Ultem

Machining Ultem in Southern California for over 40+ years!

As is the case with many high performing plastics, understanding the machining characteristics of Ultem® is critical to being able to produce a precision part. Managing stresses in the material is a critical skill required to machine complex tight tolerance parts. Upland Fab has been machining Ultem® and other high performing plastics for over 40 years and has the processes and equipment in place to achieve the right results. When added strength is required, engineers turn to 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 on a regular basis giving us the experience needed to machine your part correctly the first time.

Ultem® (PEI) Excellent Strength Material

When engineers are looking for a material with excellent strength and stiffness at elevated temperatures they often turn to Ultem®. Ultem® is considered one of the best materials for maintaining excellent strength properties at high temperatures (200°C) while maintaining great dimensional stability. These properties lend itself to many applications in the Aerospace industry in both aircraft and spacecraft applications as well as the Medical industry where repeated sterilization cycles may be required.

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.

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.

Upland Fab's Top-Flight Communication

Our ability to machine Ultem® is just one of the things that make Upland Fab different. Reliable communication is a top priority at Upland Fab; as an Upland Fab customer, you’ll have a single point of contact. This way, we ensure that you constantly receive updates as your project moves forward.
