Delrin FAQ

What tolerances can you hold on Delrin parts?

We routinely hold ±0.002″ (±0.05 mm) and can achieve ±0.001″ (±0.025 mm) on critical features with proper fixturing.

Do you offer post-machining finishing?

Yes—we provide deburring, chamfering, polishing, and light buffing to ensure smooth, burr-free edges.

Can you join or assemble Delrin components?

We offer adhesive bonding and ultrasonic welding services for Delrin assemblies, as well as mechanical fastening prep.

What size parts can you handle?

Our mills and lathes accommodate Delrin blocks and rods up to 24″ long and 12″ in diameter.

Is this manufactured in-house?

Some Delrin components are machined in-house, while others are produced through our trusted Canadian supplier network. Pearson oversees sourcing, QA, and logistics to ensure consistent quality.
