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 quote

Send STEP/STP, 2D drawings, material, finish, quantity, tolerance notes, deadline, destination country, and NDA needs. Complete RFQs are reviewed within 24 hours.

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.

Périmètre et délai

Le périmètre d inspection peut influencer coût et délai

CMM, FAI, traçabilité matière, validation de finition et preuve d emballage doivent être choisis avant production car chaque élément modifie le temps d inspection, la préparation du rapport et le planning.

Demander un exemple de dossier documentaire

Le CMM est utile quand

la pièce comporte des appels GD&T, des références sensibles, des alésages critiques ou des dimensions difficiles à vérifier avec de simples jauges.

Le CMM peut être inutile quand

le prototype est un modèle esthétique précoce, un boîtier peu critique ou un échantillon concept où photos et contrôles manuels clés suffisent.

Le FAI est utile quand

la première pièce valide une révision de plan, un lancement petite série, un fournisseur ou un plan d inspection avant libération d autres pièces.

La traçabilité matière compte quand

l acheteur doit confirmer alliage, grade résine, traitement thermique, lot ou documents de conformité avant approbation ou expédition.

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.
