Torlon® Machining

Torlon

Precise machining of Torlon® can be very difficult especially in complex geometries involving large amounts of material removal. Upland Fab’s Engineers have over 2 decades of experience creating precise components in many grades of Torlon®. One of the many battles faced in machining Torlon® is managing the stresses in the material. Upland Fab’s internal annealing capabilities combined with the vast experience in machining Torlon® allow us to manage these stresses efficiently to produce stable parts the first time. Torlon® grades such as 4301 and 5530 can be extremely abrasive, wearing out tools at a rapid pace. Upland Fab’s engineers understand this up front and plan accordingly. This helps the customer get their parts on time and to print by removing any potential delays.

Torlon® (PAI) One of the Highest Performing Plastics on the Market!

Torlon® (Polyamide-Imide or PAI) is considered one of the highest performing engineering plastics on the market today. Torlon® exhibits excellent dimensional stability with low creep at continuous operating temperatures of 500°F. Torlon® is found throughout many industries such as Aerospace for satellite components; it’s used in the semiconductor industry for socket assemblies; it’s used in the fluid transfer industry for pump components and valve seals.

Using CNC Technologies for Machining Torlon® Parts

Upland Fab employs the use of multi-axis machining when working with Torlon®. 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. Managing moisture absorption is critical to holding precise tolerances in Torlon®, Upland Fab’s ability to dry machine (no coolant) Torlon® reduces the effect of moisture absorption.

The DPD/MBD processes in place at our facility allow us to make complex Torlon® parts directly from a customer supplied CAD model. The result? Accurate and cost-effective parts.
