Core selling points
What procurement teams usually need to verify
Direct answer for sourcing teams
Use Bohua when the RFQ needs A356 material review, cast-plus-machined scope, and supplier evidence rather than a catalog-only response.
A356 route before price
The quote starts with alloy, temper, wall thickness, machining stock, porosity-sensitive zones, and inspection burden before unit price is compared.
Supplier package visibility
Buyer-facing records such as material certificate, CMM report, X-ray scope, leak test, FAI, or PPAP are discussed before tooling approval.
Comparison intent
How buyers usually compare China suppliers before RFQ
OEM drawing review
Bohua approach
A356 RFQs are reviewed against drawing, tooling status, annual volume, machining datums, and validation records.
Typical market gap
A supplier quotes a raw casting from weight and delays machining or inspection discussion until after sampling.
A356-T6 planning
Bohua approach
T6, machining allowance, distortion risk, and sample validation are discussed as one route.
Typical market gap
Heat treatment, machining, and inspection are quoted as separate add-ons without a shared launch plan.
Export-ready RFQ
Bohua approach
Destination, Incoterm, packaging, approval records, and serial-production assumptions are captured during RFQ review.
Typical market gap
Commercial terms stay vague until late-stage negotiation, making supplier comparisons harder.
RFQ micro-conversion
Send an A356 OEM supplier RFQ that can be reviewed without guesswork
A useful A356 RFQ shows drawing revision, alloy/temper, machining scope, inspection records, launch timing, and annual volume before tooling discussion.

New A356 OEM casting RFQ
Best when
The buyer has a drawing package and needs a manufacturing quote for a new A356 or A356-T6 part.
Send these inputs
PDF + STEP, alloy/temper target, annual volume, machining scope, inspection package, destination, and Incoterm.
Pressure-conscious A356 housing
Best when
Pump, valve, or sealed housing programs need leak-test criteria, sealing faces, and porosity-sensitive zones reviewed before tooling.
Send these inputs
Pressure or leak-test method, acceptance criteria, CNC datums, sealing faces, X-ray scope, CMM needs, and annual demand.
Second-source supplier review
Best when
Procurement needs an alternate supplier for an existing A356 program and wants tooling, qualification, and approval risks visible.
Send these inputs
Current drawing revision, existing tooling status, supplier issue, pilot quantity, approval records, and target qualification date.
RFQ checklist
What to send if you want a serious quotation
• PDF plus STEP drawing package with critical datums, machined faces, and sealing or pressure areas marked
• A356, A356-T6, ZL114 equivalent, or buyer-approved standard with any mechanical target
• Annual volume, pilot quantity, sample target, and expected serial launch window
• Tooling status: new, duplicate, transfer, redesign, or supplier-change review
• Inspection requirements: CMM, X-ray, leak test, material certificate, FAI, PPAP, or traceability format
Pricing / MOQ / lead time / tooling / testing
Commercial questions procurement teams ask before supplier approval
| Typical RFQ stage | Drawing-ready A356 OEM programs, second-source review, or supplier comparison before tooling release. |
|---|---|
| Process fit | Gravity casting for many A356 structural or pressure-conscious parts; low-pressure reviewed when geometry and volume justify it. |
| Tooling timing | New permanent-mold tooling is typically planned as a 5-8 week window before T1 sampling once inputs and buyer approvals are defined. |
| MOQ | Reviewed by tooling route, machining cycle, part weight, inspection burden, and prototype-to-serial plan. |
| Price basis | Quoted after alloy, casting route, machining scope, heat treatment, inspection, volume, packaging, and Incoterm review. |

Questions buyers usually ask before contacting a manufacturer
Is Bohua an A356 OEM supplier or only a casting shop?
Bohua reviews A356 projects as OEM drawing-based programs, including casting route, tooling, CNC machining, inspection records, and export assumptions. The buyer should send drawings, annual volume, alloy or mechanical target, and approval requirements.
Which A356 parts are a strong fit for Bohua?
Pump housings, valve bodies, gearbox housings, motor housings, structural brackets, manifolds, and machined housings are typical fits when the drawing requires heat-treatable aluminum, machining stability, or pressure-conscious review.
Can Bohua support A356-T6?
Yes. Bohua can review A356-T6 programs where heat treatment, dimensional stability, CNC machining, and validation records are part of the RFQ scope. The final route depends on drawing, wall thickness, tooling, and buyer acceptance criteria.
What should an A356 OEM RFQ include?
Send PDF plus STEP drawings, A356 or A356-T6 requirement, annual volume, machining scope, surface treatment, inspection package, leak-test or X-ray needs, destination, Incoterm, and target timing.
Does Bohua publish fixed A356 prices?
No. A useful quote depends on casting route, tooling, heat treatment, machining scope, inspection burden, quantity, packaging, and export terms, so pricing is confirmed after drawing review.
