Practical, no-nonsense guidance on machining and fabricating engineering plastics — from a shop that's been doing it since 1968.
What UHMW polyethylene is, why it moves after cutting, and a shop-floor guide to machining it — thermal expansion, stress relief, fixturing, and the tolerances that are realistic on a wear material.
