RFQ Inputs

Information that speeds up supplier review

The fastest way to move from browsing to a real RFQ is to make the engineering and commercial assumptions visible in the first message. Use this list before contacting Bohua or comparing another supplier.

+2D drawing in PDF with revision status and critical dimensions marked
+3D model such as STEP or IGES when available
+Alloy, temper, mechanical requirement, or equivalent material standard
+Annual volume range, sample quantity, pilot quantity, and expected ramp timing
+Casting process preference if already fixed, or note that process selection is open
+Machining scope: datums, bores, sealing faces, ports, threads, O-ring grooves, surface finish
+Quality records required: material certificate, CMM report, X-ray, pressure-tightness test, PPAP, FAI, or traceability format
+Commercial notes: tooling ownership, Incoterm, destination, packaging requirement, NDA requirement, and target launch timing

Evidence Path

What evidence buyers can ask for

Prequalification

Company facts, certification scope, process list, equipment list, and export contact path

Drawing review

DFM questions, wall thickness, draft, machining allowance, datum logic, and process fit

Sampling

T1 sample plan, inspection record scope, open-issue list, correction loop, and buyer approval route

Serial production

Control plan, batch traceability, dimensional reports, material certificates, and shipment documentation as required by program scope

Second source

Existing part review, fixed-interface notes, tooling status, material match, and comparison against current supplier assumptions

Ready to prequalify Bohua for a casting RFQ?

Send one drawing package, supplier questionnaire, or second-source comparison target. Bohua can respond with process fit, open questions, and the evidence path needed for your approval process.

FAQ

Supplier capability sheet questions

What is an aluminum casting supplier capability sheet?

A supplier capability sheet is a concise prequalification page that summarizes company facts, casting processes, alloys, machining and inspection support, quality records, export readiness, and the RFQ information needed before quotation.

Can this page be used for supplier prequalification?

Yes. It is designed as a first-pass prequalification reference for buyers, SQE teams, and sourcing teams. For formal approval, buyers should request current certificates, project-specific inspection records, and any customer-specific documents required by their quality system.

What should buyers send after reviewing the capability sheet?

Send the drawing, 3D model if available, alloy or mechanical requirement, annual volume range, machining scope, inspection record requirements, tooling status, and any NDA or export documentation requirements.

Does Bohua quote finished cast and machined parts?

Yes. Bohua can review casting route, CNC machining scope, inspection requirements, and export assumptions together so the buyer can compare finished-part sourcing rather than only raw casting price.
