Working with Aurum PD450 ESD
Is Aurum PD450 easy to machine?
Machines cleanly with sharp carbide/PCD tooling and light cuts; keep parts cool and stress-relieve (anneal near 250 °C) before finish passes to avoid distortion.
Can Aurum PD450 be welded?
No solvent bonding; joining by hot-plate/ultrasonic welding above ~390 °C or by high-temperature polyimide adhesives, more commonly mechanically fastened.
Can Aurum PD450 be formed, bent or molded?
Dry 4–8 h at 180 °C, mold at 400–425 °C melt with 180–230 °C mold to crystallize; low-shear screws, high injection pressure and hot runners suited to high-temp resins.
What surface finishes work on Aurum PD450?
Naturally amber-to-brown, needs no coating; plasma or chemical etching improves adhesion for metallization, sputtering and printed circuit applications.
