Second-source aluminum casting RFQ guide for buyers qualifying a backup supplier before supply risk becomes urgent

Use this RFQ page when a buyer needs a second source for existing aluminum castings, transfer tooling, backup capacity, sample validation, or PPAP/FAI documentation.

This page is for procurement, SQE, and operations teams comparing backup casting suppliers with a real approval path, not only a lower unit-price quote.

What procurement wants clarified

Commercial checkpoints before the buyer sends the RFQ

• Second-source RFQs should state the risk being reduced: quality instability, delivery exposure, cost pressure, capacity limits, or business continuity.

• Tooling status changes the quote: new tool, duplicate tool, transfer tool, existing fixture, or buyer-owned tooling each has a different approval path.

• Sample validation should test communication, dimensional control, machining scope, inspection records, and packaging assumptions before serial allocation.

• A serious backup supplier quote should separate unit price, tooling, sample cost, machining, inspection, PPAP/FAI records, packaging, Incoterm, and ramp timing.

RFQ action

Use this page as the last stop before contact

The goal is to replace vague contact intent with a quote that includes drawing/spec, material, quantity or MOQ, tooling, lead time, testing, and reply path.

Buyer checklist

What to include so the quote is real

• Current drawing package with revision status and any approved deviations or open engineering changes

• Current supplier pain points if shareable: quality, delivery, documentation, cost, communication, capacity, or tooling wear

• Part family and risk level: pump housing, valve body, gearbox housing, bracket, intake manifold, or other custom casting

• Tooling status: new tool, duplicate tool, transfer tool, trim fixture, machining fixture, core box, and ownership notes

• Current and target annual volume, pilot quantity, backup allocation target, and whether this is standby or active dual-source supply

• Required validation package: sample order, FAI, CMM, material certificate, leak-test record, PPAP, control plan, or customer-specific documents

• Commercial notes: destination, Incoterm, packaging, forecast cadence, target qualification date, and preferred contact path

Commercial comparison

Questions that separate a serious quote from a placeholder quote

Second-source goal	State whether the buyer needs backup capacity, cost-down leverage, quality recovery, supplier replacement, or transfer-tool review. The answer changes the quote and qualification plan.
Tooling route	New tooling gives more control, transfer tooling may reduce launch cost, and duplicate tooling can support dual-source continuity. Each option should be quoted separately when relevant.
Approval evidence	Sample parts alone are rarely enough. Buyers should define FAI, CMM, material records, leak-test records, PPAP, control plan, or traceability needs before awarding a second source.
Allocation plan	Standby source, pilot source, 80/20 split, 50/50 split, and emergency replacement programs all require different MOQ, inventory, communication, and scheduling assumptions.
Risk language	The RFQ should describe the risk without exposing confidential supplier names, pricing, or customer programs until NDA and commercial terms are handled.
