Machining & welding at Zedaxis

Machinability

Good

Machines cleanly; anneal for tight tolerances; avoid coolants/cleaners that craze it (aromatics, ketones).

Weldability

Plastic weld only

Solvent/adhesive bonds well; hot-plate weldable.

Standards & international equivalents

SystemDesignation
ENISO 1043-1 "PC"; ISO 7391
DINDIN 7728 PC
ASTMD3935

Equivalents & alternatives: Lexan, Makrolon. Alt: acrylic/PMMA (optics, stiffer, brittle), PETG (thermoforming).

Polymers are specified by ISO/ASTM abbreviation, grade and filler (not by cross-national metal designations) — match by manufacturer datasheet.
