# Packaging & Automation Machinery Parts — CNC Machined to Drawing

> Sinbo Precision (sinbo-machining.com) machines 40 packaging & automation 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.

Food-grade and packaging machinery spare parts are made to drawing, often overnight: ground rollers, cams, timing pulleys, product guides and changeover parts in 6061, 303/304 stainless and PEEK, hydrocarbon-washed when food contact is adjacent. Send us the OEM drawing number and a sketch — we reverse-engineer wear parts fast.
