A356-T6 pressure-tight pump housing RFQ guide for leak-test, CNC machining, and PPAP-ready quote packages
Use this RFQ page when an A356-T6 pump housing quote depends on pressure or leak-test criteria, CNC datums, sealing faces, tooling status, and inspection documentation.
This page is built for procurement, SQE, and engineering buyers who already know the part family and need a drawing-based supplier response instead of a generic catalog answer.

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.

What to include so the quote is real
• 2D PDF drawing with revision status, marked critical dimensions, and sealing or pressure-related features
• STEP or IGES model if available, especially for ports, internal passages, ribs, bosses, and machining allowances
• A356-T6 target or accepted equivalent alloy and temper notes
• Leak-test medium, pressure, hold time, acceptance criteria, sampling plan, and record format
• CNC machining scope: datums, bores, threads, O-ring grooves, gasket faces, flatness, perpendicularity, and surface finish
• Tooling status: new tool, current supplier tool transfer, correction tool, or prototype-to-production plan
• Annual volume, pilot quantity, MOQ target, destination country, Incoterm, packaging, and launch timing
• Inspection package: CMM, material certificate, X-ray or CT expectation, FAI, PPAP, control plan, or traceability requirement
Commercial comparison
Questions that separate a serious quote from a placeholder quote
| Leak-test definition | A serious RFQ states method, medium, pressure, hold time, pass/fail criteria, and whether testing is sample-based or lot-based. |
|---|---|
| Casting route | A356-T6 pump housings often need casting-route review before price comparison because wall thickness, feed path, machining exposure, and heat treatment change risk. |
| CNC scope | Quote accuracy improves when buyers mark datums, bearing or port bores, gasket faces, O-ring grooves, threads, and surface-finish expectations. |
| Tooling risk | New-tool and transfer-tool RFQs should separate mold condition, sample correction loop, machining fixture status, and approval records. |
| Documentation | PPAP, FAI, CMM, material certificates, leak-test records, and traceability should be quoted as part of the supply scope instead of added after samples. |

Questions buyers usually ask on quote-intent pages
What makes an A356-T6 pump housing RFQ different from a generic casting quote?
The quote should include heat-treatment assumptions, pressure or leak-test criteria, CNC datums, sealing faces, tool status, and inspection records. A generic casting quote often misses the details that drive cost and sample approval risk.
Should buyers send leak-test requirements before the final standard is frozen?
Yes. Even preliminary leak-test intent helps the supplier evaluate porosity risk, gating or feeding assumptions, machining sequence, and whether inspection cost should be included in the first quote.
Can Bohua review both casting and CNC machining scope for a pump housing?
Yes. Buyers should mark the casting route, heat treatment, datums, ports, bores, sealing surfaces, threads, and required inspection reports so casting and machining are reviewed together.
What should be stated for PPAP or FAI readiness?
State whether the buyer needs PPAP, FAI, CMM reports, material certificates, leak-test records, control plan, traceability, or customer-specific forms. The required documentation changes the quote scope.
