Why first-article inspection matters before volume release for drawing-based precision hardware programs.
First-article inspection aligns process, gauges and critical characteristics before volume releases. It reduces the risk of discovering print mismatches only after inventory builds.
FAI depth follows the drawing and purchase agreement — not a generic shop default. Call out CMM or special gauges early when required.
After approval, in-process and final inspection sustain the release plan. Learn more on the Quality page or start an RFQ.
Send drawings, material, quantity and inspection requirements. Zhuocheng will review manufacturability and recommend a process route.
Specify Ra or equivalent surface finish only where function requires it, and note sealing, bearing or cosmetic zones so machining and inspection stay aligned.
A useful CMM report ties measured features to drawing callouts, revision, method notes and pass/fail results so buyers can release parts with confidence.
Mark critical dimensions clearly and keep reference dimensions informational so suppliers focus inspection and process control where the design actually requires it.
