Before quote
Send STEP/STP, 2D drawings, material, finish, quantity, tolerance notes, deadline, destination country, and NDA needs. Complete RFQs are reviewed within 24 hours.
Quality & evidence
Quality proof for CNC machining and rapid prototyping buyers
Use this page to decide what evidence to request before production: DFM notes, process photos, CMM or FAI checks, material certificates, finish samples, packing photos, and export handoff details.
Before production
Ask for DFM feedback, process route, critical dimension plan, surface finish feasibility, material availability, and confirmation of what will be inspected.
Before shipment
Request first article photos, CMM or FAI checks when applicable, material certs when available, finish photos, packing photos, and carrier handoff details.

Sample only. These files are not certificates or default shipment reports. COC, material certificate, dimensional report, CMM, FAI, finish approval sheet, packing checklist, and export handoff evidence must be agreed during RFQ.
Inspection documents
What DFocus can provide when the project requires it
Quality evidence depends on the part, tolerance, material, and inspection scope. We keep the promise precise: these documents are available when agreed during RFQ, not implied for every order by default.
FAI report
Useful for first article approval, drawing revision confirmation, and low-volume production launch.
CMM / dimensional check
Best for critical dimensions, GD&T callouts, datum-sensitive features, and fit-critical assemblies.
Material certificate
Available when material traceability matters and the requested grade can be sourced with paperwork.
Finish and packing proof
Photos of cosmetic surfaces, color samples, masking, protective packing, labels, and export carton condition.
Umfang und Zeitplan
Prüfumfang kann Kosten und Lieferzeit beeinflussen
CMM, FAI, Materialrückverfolgbarkeit, Finish-Freigabe und Verpackungsnachweis sollten vor Produktion ausgewählt werden, weil jeder Punkt Prüfzeit, Berichtserstellung und Projektzeitplan verändert.
Beispiel-Dokumentationspaket anfordernCMM ist sinnvoll, wenn
Das Teil GD&T-Angaben, datumsabhängige Merkmale, passungskritische Bohrungen oder Maße hat, die mit einfachen Lehren nicht zuverlässig prüfbar sind.
CMM ist eventuell nicht nötig, wenn
der Prototyp ein frühes Optikmodell, ein Gehäuse mit lockerer Passung oder ein Konzeptmuster ist, bei dem Fotos und manuelle Kernprüfungen für die Entscheidung reichen.
FAI ist sinnvoll, wenn
das Erstmuster eine Zeichnungsrevision, Kleinserie, Lieferantenfreigabe oder einen Prüfplan vor weiteren Teilen absichert.
Materialrückverfolgbarkeit ist wichtig, wenn
der Käufer Legierung, Harzklasse, Wärmebehandlung, Chargenidentität oder Compliance-Unterlagen vor Freigabe oder Versand bestätigen muss.
Quality proof FAQ
Can every order include CMM or FAI reports?
No. CMM and FAI reports should be agreed during RFQ because they affect inspection time, cost, and schedule.
Can I request proof before shipping?
Yes. For suitable projects, DFocus can share production photos, finish photos, key measurement evidence, and packing photos before shipment.
What should I send for a faster quote?
Send CAD files, 2D drawings for critical tolerances, material, quantity, finish, inspection needs, shipping country, target deadline, and NDA requirements.
Certification boundary
Certification and documentation boundary
DFocus does not treat every project as certification-backed by default. Inspection reports, material certificates, COC, FAI/CMM records, finish samples, packing photos, and export handoff evidence must be agreed during RFQ and quoted with the required scope.
What this means
Your quote can define the evidence package needed before shipment, including dimensional checks, material traceability, process photos, and packing proof.
What this does not mean
A public page statement is not a certificate, regulated-device approval, or blanket system-certification guarantee. Certified entity, certificate number, scope, and expiry must be shown before a certification claim is used.
Before you quote
Tell engineering whether you need CMM, FAI, material certs, COC, finish photos, packing photos, automotive submission inputs, NDA, or export documentation.
