Enjoy RapidDirect’s expertise in PAI (Torlon) CNC machining. Stand out in your industry with our CNC machining solutions tailored to your unique needs.
Polyamide-imide (PAI), known commercially as Torlon, is a high-performance engineering thermoplastic. PAI combines high strength, excellent thermal stability, and superior chemical resistance, making it an ideal material for demanding applications. In CNC machining, PAI’s unique properties allow for the production of parts that perform reliably under extreme conditions. Its high tensile and compressive strength, combined with excellent wear resistance, make it suitable for components exposed to mechanical stress and high temperatures.
| Price: | $$ | Available PAI at RapidDirect: | PAI 4203, 4503, 4301, 4501 |

PAI stands out for its superior toughness and ability to withstand extreme temperatures and harsh chemicals. This material is perfect for high-stress environments where reliability is crucial. Discover why PAI material is a top choice for advanced CNC machining projects.
| Tensile Strength (MPa) | Flexural Strength (MPa) | Compressive Strength (MPa) | Flexural Modulus (GPa): | Impact Strength (Notched Izod) | Hardness (Rockwell) | Thermal Conductivity (W/m·K) |
|---|---|---|---|---|---|---|
| 150 - 200 | 240 - 345 | 138 - 207 | 7.6 - 10.3 | 53 - 106 | M109 - M113 | 0.26 |
At RapidDirect, we offer professional surface finishing services to enhance the functionality and appearance of your custom CNC machined PAI parts. Our expertise ensures high-quality finishes that meet your exact specifications.
PAI machining offers a unique blend of advantages and challenges that need to be considered to optimize its application in various projects.
In CNC machining of PAI, tolerances of ±0.125mm are achievable. This level of precision allows for the production of highly accurate parts that meet stringent specifications. The material’s stability during machining helps maintain these tight tolerances, ensuring consistency across multiple parts and production runs. Specialized equipment and skilled machinists are essential to achieve and maintain these tolerances.
Common parts produced using CNC machined PAI include bearings, seals, electrical connectors, and structural components. In the aerospace industry, PAI is used for high-performance bearings and bushings due to its excellent wear resistance and thermal stability. In the automotive sector, it’s utilized for components like transmission parts and throttle bodies. Electrical connectors made from PAI benefit from its excellent dielectric properties and thermal resistance. Additionally, PAI is used in industrial machinery for parts that require high strength, low friction, and resistance to harsh chemicals.
