The manufacturer maintains or pursues AS9100D and ISO 9001:2015 certification from an accredited registrar. Material suppliers appear on an Approved Supplier List with documented qualification records.<\/p>\n<p>The business case for a rigorous QC system continues to strengthen. <a href=\"https:\/\/thomasnet.com\/insights\/states-benefiting-from-reshoring\" target=\"_blank\" rel=\"noindex nofollow\">Manufacturers report completing reshoring operations and pursuing reshoring plans<\/a>, which increases demand for domestic partners with auditable quality systems. At the same time, <a href=\"https:\/\/www.oxebridge.com\/emma\/rapid-as9100\/\" target=\"_blank\" rel=\"noindex nofollow\">AS9100 certification is often demanded by aerospace primes such as Boeing and Lockheed as a requirement to do business with them for applicable suppliers<\/a>. Programs that lack a structured QC framework early in the lifecycle tend to accumulate nonconformances, traceability disputes and audit findings that require significant effort to correct.<\/p>\n<h2>The Eight-Phase Build-to-Print Quality Control Process<\/h2>\n<h3>Phase 1: Document Review and Revision Control<\/h3>\n<p><strong>Inputs:<\/strong> Customer drawing package, specifications, purchase order quality clauses. <strong>Outputs:<\/strong> Approved manufacturing router, revision-controlled work instructions.<\/p>\n<p>Every drawing characteristic is ballooned before any material is cut. <a href=\"https:\/\/borgdesign.com\/resources\/aerospace-supplier-qualification-checklist\" target=\"_blank\" rel=\"noindex nofollow\">A strong FAI package records every drawing characteristic with actual measured values tied to the drawing revision and inspection date, including ballooned drawing cross-references and material certifications<\/a>. This discipline supports revision control by tying each measurement to a specific drawing version.<\/p>\n<p>Revision control then blocks superseded drawings from reaching the shop floor. Any verbal correction at the bench bypasses this control and creates nonconformance risk. <a href=\"https:\/\/getuniqcli.com\/capabilities\/manufacturing\" target=\"_blank\" rel=\"noindex nofollow\">Each change flows through document control before reaching the shop floor<\/a>, which preserves a clean audit trail.<\/p>\n<h3>Phase 2: Incoming Material Verification<\/h3>\n<p><strong>Inputs:<\/strong> Raw material shipments, supplier Certificates of Conformance, Mill Test Reports. <strong>Outputs:<\/strong> Quarantine disposition records, approved material lot tags.<\/p>\n<p><a href=\"https:\/\/borgdesign.com\/resources\/aerospace-supplier-qualification-checklist\" target=\"_blank\" rel=\"noindex nofollow\">Material traceability requires an unbroken chain from raw stock Material Test Report through every operation to the finished part certificate<\/a>. Every incoming lot passes through a defined quarantine process, either physical segregation or validated electronic quarantine, before the quality unit issues a disposition.<\/p>\n<p><a href=\"https:\/\/cloudtheapp.com\/raw-materials-qualification-fda-and-iso-13485-requirements-for-incoming-inspection\" target=\"_blank\" rel=\"noindex nofollow\">Complete incoming inspection records include supplier and lot identification, date received, quantity received, inspection or test results, reference to the relevant specification and the disposition decision<\/a>. <a href=\"https:\/\/rscalu.com\/factory-audit-checklist\" target=\"_blank\" rel=\"noindex nofollow\">Falsified or unverifiable Mill Test Certificates present a documented risk; a compliant MTC includes heat number, chemical composition, mechanical test results with specification limits, an authorized signatory and a company stamp<\/a>.<\/p>\n<h3>Phase 3: In-Process Inspection and SPC<\/h3>\n<p><strong>Inputs:<\/strong> Work instructions, control plan, calibrated gauges. <strong>Outputs:<\/strong> In-process inspection records, SPC charts, operator-signed travelers.<\/p>\n<p>In-process checkpoints catch dimensional drift before it spreads across a lot. Statistical Process Control monitors critical characteristics, such as bend angles, hole locations and weld joint geometry, and triggers investigation when data trends toward a control limit.<\/p>\n<p><a href=\"https:\/\/ntmetals.com\/blog\/what-military-discipline-brings-to-precision-fabrication\" target=\"_blank\" rel=\"noindex nofollow\">Name-level accountability extends traceability beyond ISO 9001:2015 minimums, with every weld bead, measurement and shipped part linked to a specific operator, inspector or packer on the production traveler<\/a>. Operator-signed inspection records provide clear accountability and stand out during audits.<\/p>\n<h3>Phase 4: First Article Inspection<\/h3>\n<p><strong>Inputs:<\/strong> Ballooned drawing, production-run part, calibrated CMM or hand tools. <strong>Outputs:<\/strong> AS9102 FAIR (Forms 1, 2 and 3), material certifications, special-process certs.<\/p>\n<p><a href=\"https:\/\/scribd.com\/document\/976762227\/Jamco-FAI-Training-Materials\" target=\"_blank\" rel=\"noindex nofollow\">AS9100D clause 8.5.1.3 requires use of a representative item from the first production run to verify that production processes, documentation and tooling produce parts that meet requirements, and this activity repeats when changes invalidate the original results<\/a>. A compliant FAI package under AS9102 Rev B includes Forms 1, 2 and 3 with supporting documentation.<\/p>\n<p><a href=\"https:\/\/borgdesign.com\/resources\/aerospace-supplier-qualification-checklist\" target=\"_blank\" rel=\"noindex nofollow\">CMM-generated dimensional reports provide computer-generated data with actual measured values traceable to the inspection date, operator, machine and drawing revision, which replaces handwritten records for aerospace incoming inspection and audits<\/a>.<\/p>\n<p><a href=\"https:\/\/fabcon.com\/\" target=\"_blank\">Fabcon\u2019s CMM-equipped inspection lab can execute AS9102 Rev B first article inspections for new or transferred programs. Request a quote.<\/a><\/p>\n<h3>Phase 5: Final Audit and CoC Generation<\/h3>\n<p><strong>Inputs:<\/strong> Completed assembly, inspection records, traveler. <strong>Outputs:<\/strong> Signed Certificate of Conformance, ship-release authorization.<\/p>\n<p><a href=\"https:\/\/borgdesign.com\/resources\/aerospace-supplier-qualification-checklist\" target=\"_blank\" rel=\"noindex nofollow\">A Certificate of Conformance accompanies every shipment and states compliance to the drawing revision, material specification and applicable quality requirements<\/a>. The CoC serves as a signed statement from the supplier confirming that the part was produced to the drawing and specification.<\/p>\n<p>No shipment leaves without a quality-unit signature on the CoC and a closed traveler. This final checkpoint closes the traceability loop from raw material to shipped assembly.<\/p>\n<h3>Phase 6: Nonconformance and Corrective Action<\/h3>\n<p><strong>Inputs:<\/strong> Inspection rejections, customer returns, audit findings. <strong>Outputs:<\/strong> NCR log, root-cause analysis, CAPA records.<\/p>\n<p><a href=\"https:\/\/scribd.com\/document\/976762227\/Jamco-FAI-Training-Materials\" target=\"_blank\" rel=\"noindex nofollow\">Nonconformances identified during FAI appear on Form 3 with the NCR, DS tag or DMR reference number, affected parts move to quarantine and a partial FAI covers affected characteristics after corrective action before the FAI is considered complete<\/a>. This process prevents escape of known defects.<\/p>\n<p><a href=\"https:\/\/ntmetals.com\/blog\/what-military-discipline-brings-to-precision-fabrication\" target=\"_blank\" rel=\"noindex nofollow\">Nonconformance documentation tied to specific process steps and individual decisions, rather than generic root causes, prevents the traceability finger-pointing that occurs when multiple vendors each claim their work was compliant<\/a>. Effective handling focuses on catching, segregating and addressing defects instead of passing them downstream.<\/p>\n<h3>Phase 7: Traceability and Record Retention<\/h3>\n<p><strong>Inputs:<\/strong> All inspection records, travelers, material certs, CoCs. <strong>Outputs:<\/strong> Archived program records accessible for audit.<\/p>\n<p><a href=\"https:\/\/aqms.space\/2023\/06\/as9100-8-5-2-identification-and-traceability\" target=\"_blank\" rel=\"noindex nofollow\">AS9100D clause 8.5.2<\/a> requires organizations to identify process outputs, show status against monitoring and measurement requirements and control acceptance authority media when used. The traceability chain established in Phase 2 continues through these records.<\/p>\n<p><a href=\"https:\/\/nimblemfg.co\/as9100-rev-d-complete-guide\" target=\"_blank\" rel=\"noindex nofollow\">FAI records remain on file for the life of the program plus the contract-specified retention period, and not less than AS9100 clause 7.5 requirements for documented information<\/a>. For medical device programs, <a href=\"https:\/\/cadnexa.com\/blog-iso-13485-inspection-documentation.html\" target=\"_blank\" rel=\"noindex nofollow\">incoming inspection records, in-process inspection records and final inspection or release records combine into the Device History Record for each batch<\/a>.<\/p>\n<h3>Phase 8: Scaling QC from Prototype to Production<\/h3>\n<p><strong>Inputs:<\/strong> Validated FAI, SPC baseline, approved supplier list. <strong>Outputs:<\/strong> Production control plan, updated sampling strategy, scaled work instructions.<\/p>\n<p><a href=\"https:\/\/scribd.com\/document\/976762227\/Jamco-FAI-Training-Materials\" target=\"_blank\" rel=\"noindex nofollow\">A new or partial delta FAI occurs when a change affects form, fit or function, when manufacturing sources, processes, location, tooling or materials change, or when a lapse in production of two years occurs for any impacted characteristic<\/a>. These triggers keep validation aligned with current conditions.<\/p>\n<p>Sampling plans appear in inspection procedures and undergo review by quality assurance. <a href=\"https:\/\/cloudtheapp.com\/raw-materials-qualification-fda-and-iso-13485-requirements-for-incoming-inspection\" target=\"_blank\" rel=\"noindex nofollow\">A statistically sound sampling plan for incoming inspection, such as ANSI\/ASQ Z1.4 for attribute sampling or ANSI\/ASQ Z1.9 for variable sampling, appears in the incoming inspection procedure<\/a>.<\/p>\n<h2>Standards, Tools and Templates that Support the Eight Phases<\/h2>\n<p>The eight phases operate within a framework of industry standards and supporting tools. The primary standards governing build-to-print QC are AS9100D, <a href=\"https:\/\/www.iso.org\/standard\/62085.html\" target=\"_blank\" rel=\"noindex nofollow\">ISO 9001:2015<\/a>, <a href=\"https:\/\/www.sae.org\/standards\/content\/as9102b\/\" target=\"_blank\" rel=\"noindex nofollow\">AS9102 Rev B<\/a> for FAI and <a href=\"https:\/\/www.iso.org\/standard\/59752.html\" target=\"_blank\" rel=\"noindex nofollow\">ISO 13485:2016<\/a> for medical device programs.<\/p>\n<p>Supporting tools include ballooned drawing packages, CMM dimensional reports, production travelers, SPC control charts and an Approved Supplier List. A traceability flow diagram maps the path from raw material heat lot through each operation to the final CoC, which provides a single-page audit reference. Downloadable templates for FAI reports, CoC documents and traceability flow diagrams streamline program setup and audit preparation.<\/p>\n<h2>Aerospace Programs: AS9100D, ITAR and FAI Expectations<\/h2>\n<p>Aerospace programs carry the most prescriptive QC requirements. <a href=\"https:\/\/epsilon3.io\/behind-the-console\/iso-9001-vs-as9100-what-ops-teams-need-to-know\" target=\"_blank\" rel=\"noindex nofollow\">AS9100 Rev D adds more than 100 sector-specific requirements on top of the full text of ISO 9001, including product safety risk assessment, counterfeit parts prevention, formal configuration management and FAI<\/a>.<\/p>\n<p>AS9100D clause 8.1.4 directs organizations to plan, implement and maintain a suitable process for preventing counterfeit parts, including risk identification and control measures. ITAR registration restricts access to technical data and manufacturing processes for defense articles, which requires controlled facility access and export-compliance documentation. Fabcon holds AS9100D certification and ITAR registration and supports aerospace and defense programs with full traceability from raw material to shipped assembly.<\/p>\n<h2>Medical Device Programs: ISO 13485, Inspection Records and DHR<\/h2>\n<p>Medical device programs require a Device History Record that compiles all inspection evidence for each production batch. <a href=\"https:\/\/cadnexa.com\/blog-iso-13485-inspection-documentation.html\" target=\"_blank\" rel=\"noindex nofollow\">ISO 13485 inspection documentation must prove that the correct acceptance criteria were applied, that the person releasing the product is identified and that every record can be traced back to the specific device, batch and drawing revision<\/a>.<\/p>\n<p><a href=\"https:\/\/evokpoly.com\/feeds\/blog\/medical-injection-molding-fda\" target=\"_blank\" rel=\"noindex nofollow\">ISO 13485 requires integration of risk management per ISO 14971 into product realization, including process risk identification, risk controls and effectiveness monitoring via SPC and trend analysis<\/a>. <a href=\"https:\/\/biorep.com\/supplier-quality-management-for-iso-13485-compliant-medical-device-companies\" target=\"_blank\" rel=\"noindex nofollow\">ISO 13485 also mandates that approved suppliers appear on an Approved Supplier List following a qualification process that may include certification reviews, QMS assessments, audits and Quality Agreements<\/a>.<\/p>\n<h2>Data Center Programs: Rack QC, Cable Management and Compliance<\/h2>\n<p>Data center infrastructure programs depend on dimensional consistency across high-volume rack and enclosure builds, because fit-up failures at installation create costly rework. QC programs for this segment verify rack unit spacing, cable management aperture dimensions and grounding continuity against customer drawings.<\/p>\n<p>UL and CSA compliance documentation accompanies finished assemblies. Fabcon\u2019s ISO 9001:2015-certified quality system governs fabrication, finishing and light electromechanical assembly for data center customers, with inspection records and CoCs issued per shipment.<\/p>\n<h2>Common Multi-Vendor Challenges and How Vertical Integration Helps<\/h2>\n<p>Vendor handoff delays and traceability finger-pointing appear frequently in multi-vendor build-to-print programs. <a href=\"https:\/\/drametal.com\/blog\/supplier-factory-audit-checklist\" target=\"_blank\" rel=\"noindex nofollow\">The main risk comes from not knowing what is outsourced and who controls it, particularly for processes such as plating, galvanizing and finishing, which increases nonconformance risk from uncontrolled multi-vendor handoffs<\/a>.<\/p>\n<p><a href=\"https:\/\/procxinc.com\/single-source-vs-multi-vendor-manufacturing\" target=\"_blank\" rel=\"noindex nofollow\">When startup of a production line falls behind in a multi-vendor setup, each vendor can credibly claim its equipment is performing as specified, which leaves the manufacturer with accountability gaps that hurt throughput, yield and reliability<\/a>. A single vertically integrated partner removes these gaps by maintaining one quality system, one traveler and one CoC across fabrication, finishing and assembly.<\/p>\n<h2>Tracking Results for Build-to-Print QC<\/h2>\n<p>Key performance indicators for a build-to-print QC program include first-pass yield by part number, nonconformance rate per lot, on-time delivery against promised ship dates and audit finding closure rate. <a href=\"https:\/\/ntmetals.com\/blog\/what-military-discipline-brings-to-precision-fabrication\" target=\"_blank\" rel=\"noindex nofollow\">First-pass-yield trending by part number and operator supports stronger root-cause analysis in corrective action responses<\/a>.<\/p>\n<p>Customer-side rejection rate at receiving inspection acts as a lagging indicator that reflects the combined effectiveness of in-process inspection, FAI and final audit. Programs that track these metrics monthly can identify systemic issues before they escalate to customer escapes or audit findings.<\/p>\n<h2>Advanced Planning, IA9100 Transition and Digital QMS<\/h2>\n<p><a href=\"https:\/\/epsilon3.io\/behind-the-console\/iso-9001-vs-as9100-what-ops-teams-need-to-know\" target=\"_blank\" rel=\"noindex nofollow\">A new revision of the AS9100 series, rebranded as IA9100, is expected in late 2026 or 2027 and will align with ISO 9001:2026, with a typical two-to-three-year transition window<\/a>. Programs can begin gap assessments against draft requirements now to avoid compressed transition timelines.<\/p>\n<p>For programs scaling from prototype to mid-volume, teams review control plans and sampling strategies at each volume gate. SPC data from early production runs informs whether tighter or relaxed sampling makes sense. Electronic QMS platforms with validated software reduce the risk of uncontrolled spreadsheets.<\/p>\n<p><a href=\"https:\/\/www.i3cglobal.com\/validation-of-software-used-in-qms\/\" target=\"_blank\" rel=\"noindex nofollow\">ISO 13485:2016 clause 4.1.6 requires documented procedures for validating computer software used in the QMS prior to initial use and after changes<\/a>, and validated platforms address this requirement more reliably than ad hoc tools.<\/p>\n<p><a href=\"https:\/\/fabcon.com\/\" target=\"_blank\">Fabcon\u2019s vertically integrated facilities and digital quality systems support complex build-to-print programs from first article through sustained production. Discuss program requirements with the team.<\/a><\/p>\n<h2>FAQ<\/h2>\n<h3>What is the difference between a full FAI and a delta FAI in a build-to-print program?<\/h3>\n<p>A full First Article Inspection documents every characteristic on the drawing for a new part or a new production source. A delta FAI, also called a partial FAI, covers only the characteristics affected by a specific change, such as a design revision, tooling change or process change, when the remaining characteristics were already validated by a prior full FAI. Both types follow AS9102 standards, and nonconformances must be resolved before the FAI is considered complete.<\/p>\n<h3>How does vertical integration reduce nonconformance risk in build-to-print sheet metal programs?<\/h3>\n<p>When fabrication, finishing and assembly occur under one quality system, the traveler and inspection records follow the part through every operation without a handoff gap. Multi-vendor programs require each supplier to maintain separate records, and discrepancies between those records often create traceability disputes during audits. A single vertically integrated partner maintains one Approved Supplier List, one CoC chain and one corrective-action system, which reduces ambiguity and supports faster resolution.<\/p>\n<h3>What documentation does a build-to-print supplier need to satisfy an AS9100D audit?<\/h3>\n<p>An AS9100D audit requires documented processes for revision control, incoming material verification, in-process inspection, first article inspection per AS9102, nonconformance management, corrective and preventive action, traceability from raw material to finished assembly and record retention. The auditor traces a specific part backward from the CoC to the raw material MTR and incoming inspection record. Gaps in any link of that chain become findings. Counterfeit parts prevention procedures and configuration management records also appear under AS9100D and do not appear in ISO 9001 alone.<\/p>\n<h3>How does a build-to-print QC program scale from prototype to mid-volume production?<\/h3>\n<p>Prototype builds establish the drawing baseline and surface manufacturability issues before a full FAI becomes necessary. The first production-run part triggers a full AS9102 FAI, which confirms that the manufacturing process is capable and controlled. As volume increases, the control plan shifts to statistical sampling for stable characteristics, while critical dimensions remain on full inspection. Any volume-gate change that affects form, fit or function requires a delta FAI. Agile production cells that handle changing volumes and mixed SKUs support this scaling without a complete program restart.<\/p>\n<h3>What are the key differences between ISO 9001:2015 and ISO 13485 for build-to-print medical device fabrication?<\/h3>\n<p>ISO 13485 is more prescriptive than ISO 9001:2015 in areas relevant to build-to-print fabrication. It requires a Device History Record for each production batch, stricter incoming inspection documentation including lot traceability and disposition records, risk management integration per ISO 14971 and <a href=\"https:\/\/www.i3cglobal.com\/validation-of-software-used-in-qms\/\" target=\"_blank\" rel=\"noindex nofollow\">documented procedures for validating computer software used in the QMS under clause 4.1.6<\/a>. Supplier Quality Agreements define responsibilities for change notification, nonconformance handling, CAPA, audit rights and record retention. ISO 9001:2015 does not require these elements explicitly, which makes ISO 13485 the applicable standard for suppliers producing components or assemblies that form part of a regulated medical device.<\/p>\n<h2>Conclusion: Building a Single-Source, Audit-Ready Program<\/h2>\n<p>Build-to-print manufacturing quality control performs best when every phase, from document review through production scaling, operates under a single accountable partner with a certified quality system. Fragmented vendor handoffs introduce traceability gaps, nonconformance disputes and audit risk that downstream inspection cannot fully offset.<\/p>\n<p>The certifications and vertical integration described throughout this article are available under one roof at Fabcon, supporting build-to-print programs across aerospace, medical device, data center and energy storage applications from prototype through mid-volume production. <a href=\"https:\/\/fabcon.com\/\" target=\"_blank\">Start a build-to-print program with Fabcon and request a quote.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fabcon&#8217;s AS9100D-certified team covers every QC phase \u2014 FAI, material traceability and CoC documentation \u2014 for compliant build-to-print programs.<\/p>\n","protected":false},"author":69,"featured_media":1261,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[13],"tags":[],"class_list":["post-1262","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-contract-manufacturing-agile-production"],"_links":{"self":[{"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/posts\/1262","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/types\/post"}],"replies":[{"embeddable":true,"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/comments?post=1262"}],"version-history":[{"count":0,"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/posts\/1262\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/media\/1261"}],"wp:attachment":[{"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/media?parent=1262"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/categories?post=1262"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/fabcon.com\/articles\/wp-json\/wp\/v2\/tags?post=1262"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
