Aluminum Casting RFQ Checklist
Ready to start? Open the formal RFQ form, then email drawing files separately. This page is a buyer checklist, not the submission form. Ningbo Bohua Mechanical Parts Co., Ltd. supports OEM buyers who need a serious aluminum casting quote, not a generic contact page. We quote gravity casting, die casting, low-pressure casting, and selected sand casting programs with machining and surface treatment support. Prepare drawings, alloy, volume, tolerance, surface treatment and inspection requirements and our team can move quickly from review to a usable manufacturing quote.
Fast quote path
Structured RFQ review for drawing-ready projects
Best first message: drawing + alloy + annual volume + machining scope.
Preferred files: PDF plus STEP.
Direct RFQ inbox: [email protected]
Processes we can quote
Choose the casting route that matches the part, volume, and quality target
Gravity casting
Best fit for A356 / ZL114 parts that need stronger mechanical performance, stable wall sections, and machining-friendly quality.
Die casting
A strong route for ADC12 programs that need efficient production, good surface finish, and repeatable volume output.
Low-pressure casting
Useful when buyers need better fill control, stable structure, and a cleaner route for selected housing and automotive parts.
Sand casting
A flexible option for selected lower-volume or more complex geometries before moving into a higher-volume production route.
What to send for quotation
RFQ inputs that help us quote faster and more accurately
→Specify inspection scope early: state PPAP level, X-ray zones, CMM datum scheme, and pressure-tightness method in the first message so inspection cost is visible from the start.
→Include pressure or sealing requirements with the drawing — not after samples — to allow process route and machining datum review before tooling is released.
→Export note: confirm your preferred term (EXW, FOB Ningbo/Shanghai, CIF, DAP/DDP as needed) so packaging, freight, and documentation assumptions are part of the initial quote.
Why buyers use this page
A direct RFQ page for commercial-intent search traffic
This page is built for searches like aluminum casting RFQ, aluminum casting quote China, and request quote aluminum parts China.
Instead of pushing buyers into a generic contact page, it frames the quote path around process, drawing quality, and purchasing inputs.
If your team already has drawings ready, go straight to the formal RFQ page or email and skip the research loop.

Factory evidence
Evidence buyers can verify before releasing a drawing-based aluminum casting RFQ order
Ningbo Bohua Mechanical Parts Co., Ltd. operates an NQA-certified IATF 16949 quality system. The current certificate covers manufacturing of aluminum alloy cast parts and is valid through 2027-11-20.
Capability does not mean every inspection method is automatically included. The drawing, CTQs, sampling level, records, and acceptance criteria must be agreed in the RFQ and control plan.
Drawing to evidence
Define the record before comparing supplier quotes
| Checkpoint | Bohua capability evidence | Buyer must define |
|---|---|---|
| Material identity | Oxford OES and project material certificates | Alloy designation, temper, governing standard, and certificate format |
| Internal soundness | Unicomp UNC-160 and Y.MU2000-D X-ray capability | Critical zones, inspection frequency, and acceptance reference |
| Dimensional approval | Hexagon Global S and NANO Metrology CMM capability | Datums, CTQs, sampling plan, and report layout |
| Pressure tightness | Dedicated pressure-tightness testing workshop | Medium, pressure, hold time, allowable leakage, and test stage |
| Submission package | PPAP documentation can be provided up to Level 5 according to project requirements. Heat/serial traceability. | PPAP level, FAI scope, retention period, and change-control requirements |
FAQ
Buyer questions before sending an aluminum casting RFQ
What information should I send for an aluminum casting RFQ?
Send 2D drawings, 3D models (STEP preferred), alloy or mechanical requirements, annual volume, secondary operations scope, surface finish, and quality review requirements. The more buyer-side decisions are visible up front, the faster we can quote process route, tooling, and lead time without back-and-forth.
What affects aluminum casting cost?
Part weight and alloy, casting process selection (gravity vs low-pressure vs HPDC vs sand), secondary operations scope, tooling complexity, annual volume, quality review package (internal-soundness verification, dimensional verification, casting integrity review), heat treatment, surface treatment, and packaging/export terms. RFQs that fix the casting process and secondary operations scope upfront converge to a real quote faster.
How long does an aluminum casting project take?
Bohua's confirmed tooling-to-T1 reference is 45 days standard; 35 days expedited. Sample approval, machining validation, heat treatment, inspection records, and buyer response time affect the total launch plan.
How should buyers evaluate an aluminum casting supplier in China?
Verify the quality-system certificate, issuer, dates, and scope; then check process, secondary-operation, inspection, documentation, and traceability capability. For Bohua specifically: Bohua Casting operates under an NQA-certified IATF 16949 quality management system. ISO 9001 requirements are incorporated within the IATF 16949 system; Bohua does not currently hold a separate ISO 9001 certificate. ISO 14001 certification is under application.
How does Bohua approach part qualification and documentation?
PPAP documentation can be provided up to Level 5 according to project requirements. Dimensional reports, material records, process flow, control plans, PFMEA, MSA, and first-article requirements are confirmed from the project scope before tooling release.
