What We Review Before RFQ Release

Before RFQ release, engineering review confirms process fit, drawing alignment, CTQ feasibility, and document scope. RFQ review starts with the 3D CAD model, 2D drawing, material callout, target volume, and CTQ requirements to ensure a controlled release path.

Review Summary and Technical Markup

Pre-quote engineering review with CTQ output and approval package evidence
Technical Markup: CTQ & Approval Package Planning

Every submitted CAD package is reviewed to turn geometry data into a documented engineering result. This helps your team see which features drive risk and which tolerances require pre-production feasibility checks.

Review Category Production Impact
Geometry & Data Alignment of CAD, 2D drawing, and BOM structure to prevent revision mismatch.
Tolerances & Datums Feasibility of CTQ dimensions for repeatable inspection and functional mating.
Validation Scope Definition of release criteria and required approval documents (FAI, PPAP).

CTQ Control Workflow

Step 01

Input Completeness Review

Verification of 3D models and 2D drawings to confirm feature clarity, datum logic, and revision status before quoting.

Step 02

Tolerance Feasibility Assessment

Review of CTQ features against process capability to determine if verification requires CMM probing or FAI.

Step 03

Transfer & Risk Planning

Alignment of material grade, volume, assembly requirements, and document scope before production locking.

Medical Verified material certs, burr condition, critical feature control. Material documentation, function-critical verification.

When We Are Not the Right Fit

Not every RFQ should move directly to quote or production release. This section defines the project conditions that require technical clarification, re-routing, or decline before engineering commitment to ensure technical alignment.

Process Mismatch

Commodity Sourcing with No Engineering Review

This workflow is intended for custom, drawing-driven components that require technical feasibility review, process selection, and controlled production planning. We are not a fit for catalog sourcing or broad purchasing requests for off-the-shelf items.

Insufficient Data

Undefined Drawings or Unstable Revision Control

We do not release programs to manufacturing without locked technical data. Programs lacking a 2D drawing, defined CTQ features, or required material specifications are flagged for clarification before quote release.

  • 3D CAD Model (STEP/IGES)
  • 2D PDF with CTQ Callouts
  • Final Material Grade
Compliance Boundary

Certifications Outside Our Declared Scope

We do not accept programs requiring certifications, regulatory controls, or legal handling outside our explicitly declared operational scope. Programs requiring AS9100 or ITAR are declined unless the required scope is verified.

Quality Planning, Traceability, and Approval Deliverables

CMM Reports and Dimensional Verification

CMM inspection and dimensional verification are applied when CTQ features, datum relationships, or program scope call for documented evidence of alignment. Inspection results are matched to the approved drawing and defined measurement strategy before release.

Review Tolerances & Standards

FAI, PPAP, and Material Certificates

For programs requiring formal validation, the document package—including FAI records, PPAP Level 1-3 elements, CoC, and raw material certificates—is defined by program requirement and customer submission levels.

Explore Quality Deliverables

Revision Locking and Lot Traceability

Drawing revision locking and lot traceability are maintained across production release and repeat supply. Raw material heat numbers and inspection records are linked where required so every part remains traceable to its engineering release.

Quality Assurance System

Validation Scope by Program Requirement

Validation is defined by program requirement, part risk, and industry expectations. Inspection scope and approval gates are set according to the drawing, CTQ features, customer submission level, and application requirements.

Engineering FAQ for Supplier Validation

What information do you need before quote release?

Before quote release, our team requires a 3D CAD model, a 2D drawing with revision control, identified critical-to-quality (CTQ) features, BOM structure for assemblies, material specifications, and any required quality deliverables like FAI or PPAP to ensure an accurate engineering assessment.

Can one supplier support prototypes, production, and assembly?

Yes. Supporting the entire lifecycle reduces handoff errors. We control tolerance stack-up and design intent from prototype builds through bridge production, ensuring that BOM alignment, labeling, and packaging requirements are defined early and maintained into final assembly.

What quality documents can be defined before launch?

The document package is defined by program requirement. Depending on project risk and industry, this may include CMM reports, FAI records, PPAP Level 1-3 elements, CoC, and raw material traceability records to ensure engineering alignment before production release.

When should a program be re-routed to a different process?

Programs are re-routed when geometry, material behavior, annual volume, or tooling ROI indicates a better process fit. For example, moving from CNC validation builds to custom injection molding when design freeze and volume justify the tooling investment.
