Start the first review with the drawing, part application, quantity plan, material direction, and known machining requirements
OEM RFQ Checklist | July 2026
What Quality Documents Should Be Discussed Before An OEM Casting Quote?
A useful casting RFQ does not need every document finalized on day one. It does need the buyer and foundry to identify which drawings, quality requirements, machining notes, and reporting expectations could change the process route, quotation, or delivery plan.

Separate What Is Needed To Start From What Must Be Agreed Before Production
For an early drawing review, a 2D drawing, application, quantity, and material direction are often enough to begin. Before tooling, trial orders, or repeat supply, the team should progressively align critical dimensions, machining datums, inspection scope, acceptance criteria, packing, and any buyer-specific document format.
Mark critical dimensions, datum areas, sealing surfaces, bores, and assembly features that may affect casting or machining decisions
State which inspection or report expectations are already fixed and which are still open for technical discussion
Treat material certificates, dimensional reports, hardness records, corrective-action formats, and PPAP-style requirements as project-specific items to confirm, not automatic promises

A Practical Document Checklist For The First RFQ
The point of this checklist is to make the first technical reply more useful. It helps the supplier ask focused questions and helps the buyer avoid receiving a price that ignores machining, quality, or delivery risk.
Drawing control: 2D drawing, 3D model if available, revision status, part name, and sample photos where useful
Application and material: operating condition, load, pressure, wear, temperature, corrosion, material grade or material direction
Machining definition: finished dimensions, critical datums, bores, threads, sealing faces, surface requirements, and tolerance notes
Inspection expectation: critical characteristics, material checks, dimensional-report needs, hardness or surface checks, and buyer-specific acceptance standards
Supply planning: trial quantity, repeat quantity, annual demand, required delivery date, packing, destination market, and NDA need if drawings are sensitive

Buyer FAQ
Questions About Casting RFQ Quality Documents
These answers help purchasing and engineering teams prepare the first RFQ without confusing project-specific requirements with generic paperwork.
Can the first casting RFQ start before every inspection document is finalized?
Yes. Start with the drawing, application, quantity, material direction, critical dimensions, and known machining or inspection needs. The first review can identify which document and acceptance details need to be fixed before production.
Which quality requirements are most important to mark on the drawing?
Mark critical dimensions, datum areas, machining faces, sealing surfaces, bores, assembly features, material requirements, hardness if relevant, and any special inspection or report request.
Should buyers ask for material certificates, dimensional reports, 8D, or PPAP support in the first RFQ?
If the project requires them, mention them at the start. These are buyer-specific requirements that should be discussed and agreed for the actual program; they should not be assumed from a general casting quotation.
What changes between a trial order and repeat production?
The same drawing may need different focus at each stage. Trial orders often prioritize feasibility and critical risk checks, while repeat supply also needs aligned inspection records, packing, change control, and delivery rhythm.
