Ultem Machining Capabilities

Plastics Machining

Medical component machined out of a specialized plastic called Ultem. This plastic component is machined, with threads and inserts added.

Portland Precision Manufacturing Company is your number one source for tight tolerance, high precision Ultem machining. Ultem is the most commonly-used of all the exotic and specialty plastic materials we work with, and our experience in machining Ultem allows us to produce high quality parts that match our customers’ designs perfectly.

With advanced CNC technology and a skilled, experienced staff, we can produce machined Ultem parts and components with tolerances within ±0.0005” or better. No part design is too simple or complex, and even the most intricate designs can be produced with perfect part-to-part repeatability. Our precision Ultem machining services are ideal for prototype parts or orders with quantities in the tens of thousands (or more).

Machining with Ultem

Ultem is a type of polyetherimide (PEI) thermoplastic, similar to PEEK. It is commonly used in optics/optical devices, aerospace applications, automotive manufacturing, medical equipment, and many other industries, especially those where high temperature work environments are common.

Ultem exhibits a number of beneficial characteristics, including:

  • Long term high heat resistance
  • Excellent strength and stiffness
  • High strength-to-weight ratio
  • Superior durability
  • Excellent dimensional stability in extreme temperatures
  • Highly resistant to cracking
  • High chemical resistance

Ultem is available in numerous different chemistries, resins, and alloys, and Portland Precision can machine all varieties will equal skill and accuracy. We also offer precision machining services for a wide range of other exotic and engineered plastics. Contact us for specific material questions or if your project requires a specialty plastic material.

Secondary Ultem Machining Services

We also offer a number of secondary operations—surface finishing, etc.—to give additional value to our precision Ultem machining services. Our secondary processing capabilities will save you time and money—we do more of the work so you don’t have to!
