About the Material

Torlon PAI (Polyamide-imide) 4301 is a wear-resistant grade of PAI that contains amounts of graphite and PTFE. Torlon PAI has a low coefficient of friction, which makes it well-suited to applications related to seals, valve seats, and bearings. In addition, Torlon PAI is a high strength material with great dimensional stability.

Material Finish

ABS has a somewhat matte finish (think lego bricks) and can be painted. Certain faces may appear more shiny depending on their geometry and how they’re machined. If painting ABS parts, finish will be dependant of the choice of paint.

Cost Saving Tip

To reduce costs, limit the number of part setups, the number of inspection dimensions or tight tolerances, and deep pockets with small radii.
