Sample And Pre-production Approval Before Anything Runs In Volume

The documented qualification flow from our own quality page: first article inspection capability study pre-production run PPAP and ECN release.

Shower Head Series produced by NingBo CM Industry Ltd.

Our quality page sets out what happens before a new part is released to production, and it is more specific than most factories publish: first article inspection, process capability study, pre-production runs to produce a limited number of samples, production part approval process, and ECN release to production after customer approval.

Not every order needs all five. Which ones apply depends on customer requirements, engineering complexity and quality constraints, in our own published wording. This page is here so you can decide which of them your programme should ask for.

Step By Step

How This Solution Runs

  1. Incoming Material Inspection

    All purchased products that go into a CM final product are subject to a technical quality control inspection, with material certifications kept on file for incoming thermoplastic resin shipments.

  2. First Article Inspection

    The first parts off the tool measured against the drawing before anything else happens.

  3. Process Capability Study

    Run where the tolerance and the volume justify it.

  4. Pre-production Run

    A limited number of samples produced under production conditions.

  5. PPAP

    Production part approval process where your programme requires it.

  6. ECN Release

    Release to production after your approval.
