Aluminum casting RFQ: send a drawing for DFM review
One drawing, the alloy and the annual quantity are enough to start. Add the leak or strength requirement if the part has one.
Not sure what to include?
The casting RFQ checklist builds a one-page project brief you can paste into the message field: part and revision, material and condition, quantities, critical requirements and tests, finish, and open questions.
What to send with the drawing
Three items start a review. The rest decide the route and the price, so add them if you have them.
| Item | Needed to start | Helps engineering decide |
|---|---|---|
| Drawing or model | Yes: PDF, STEP, STP, IGES, IGS or STL, one file up to 25 MB | Revision, units and datums on the 2D drawing |
| Alloy and temper | Yes, or write "open" | Governing standard, e.g. A356.2-T6 to a named specification |
| Annual quantity | Yes | First order, release pattern and forecast |
| Leak or pressure requirement | If the part is sealed | Medium, test pressure, allowable leak rate, test stage |
| Strength requirement | If the part carries load | Minimums, specimen location, test method |
| Current process | If converting | Forging, HPDC, gravity or billet, with the original drawing |
Routes quoted from this form
| Route | Published range | Typical parts |
|---|---|---|

Not quoted: aerospace, medical, food-contact and pressure-vessel parts; gravity, sand and investment casting, forging and additive manufacturing. Capabilities and limits
What the quotation lists
- Proposed route and alloy, or the reason a part does not fit
- Tooling, samples and validation, separate from the part price
- Machining, heat treatment, finishing and inspection included
- Open questions from the drawing review, in writing
Before or after quoting, factory visits and live video audits of the casting, machining and inspection areas can be arranged. Certifications · Casting inspection plan · A356-T6 specification
Questions about sending a drawing
- What is the minimum I need to send for a quote?
- A drawing or model, the alloy (or "open") and the annual quantity. Add the leak or strength requirement if the part has one.
- Which file formats does the form accept?
- PDF, STEP, STP, IGES, IGS or STL, one file of up to 25 MB. For a larger package, describe it in the message and agree a transfer method.
- How is my drawing protected?
- Drawings sent through the form are stored outside the public website and can be downloaded only by authorized site administrators. Tick the NDA option if you need an NDA first.
- Can we audit the factory before ordering?
- Yes. Factory visits and live video audits of the casting, machining and inspection areas can be arranged.
