PTFE machining

PEEKABSPMMA

Overview
Machining of a wide range of plastics from general-purpose materials to engineering and super-engineering plastics (PEEK, PTFE/PTFE variants, PCTFE, MC nylon grades, POM, PMMA/acrylic, ABS, paper-based bakelite, Unilet, etc.). Services include machining by machining center, milling, turning and wire EDM. We accept ultra-small lots from a single drawing/part and handle prototyping, development, and parts for industrial, medical, food, and semiconductor manufacturing equipment.
