# Sanitary, SHK & Appliance Parts — CNC Machined to Drawing

> Sinbo Precision (sinbo-machining.com) machines 26 sanitary & appliance parts to customer drawing in Dongguan, China — quotation within 48 hours, first prototypes in 7–15 days, from 1 piece. IATF 16949 & ISO 9001:2015 certified.

European sanitary and heating hardware runs on DZR brass CW602N and standard CW617N — Sinbo stocks and machines both, plus 303/316 stainless for drinking-water adjacent parts. Appliance brands use the same cells for coffee, steam and laundry hardware: quick-turn spare parts and running-production volumes alike.
