This is what a buyer checks before they shortlist metals and metalworking suppliers.
What does a buyer check before placing a casting with a new foundry?
They check the alloys you pour, the weight and size range you handle, and your inspection capability, because castings are accepted on internal soundness as much as dimensions. Pattern ownership is the commercial question that follows immediately.
A buyer is moving a casting away from a foundry that has become unreliable, and the pattern is the hostage.

First, what the product is
The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Alloys poured
The first filter, and often a hard one.
- 2
Casting process
Sand, investment, die and centrifugal casting produce different parts.
- 3
Weight and size range
A direct yes-or-no on the buyer's part.
- 4
Annual tonnage and volume band
Prototype, low volume and series suit different foundries.
- 5
Machining capability
Whether you supply as-cast or finish-machined.
- 6
Pattern and tooling ownership
The question that decides whether a transfer is possible.
- 7
Achievable tolerance and surface finish
Determines the machining allowance required.
Then the paperwork
Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.
| Document | What it proves | Where it belongs |
|---|---|---|
| Material test certificateAsked at: with delivery | Chemistry and mechanical properties of the poured alloy | Per shipment |
| Non-destructive test reportAsked at: critical castings | Radiographic, ultrasonic or dye penetrant results for internal soundness | Per shipment |
| Dimensional inspection reportAsked at: first article and on request | Conformity to the casting drawing | Per shipment |
| First article inspectionAsked at: before series release | Full verification before series production begins | Name it, share on request |
| ISO 9001 or sector certificationAsked at: vendor approval | Quality system, plus automotive or pressure certification where relevant | Publish it |
| Pattern ownership termsAsked at: before the pattern is made | Who owns the pattern and what happens at end of life | Publish it |
| Simulation or methoding capabilityAsked at: technical assessment | That solidification is engineered rather than guessed | Name it, share on request |
The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.
The buyer asks: What does a buyer check before placing a casting with a new foundry?
A few suppliers get compared side by side:
A supplier with ISO 9001 or sector certification on the page
Quality system, plus automotive or pressure certification where relevant
A supplier with Pattern ownership terms on the page
Who owns the pattern and what happens at end of life
A supplier with First article inspection ready to send
Full verification before series production begins

What a useful enquiry looks like
A form that collects these fields can be answered properly the first time. A form that collects a name and a message cannot.
Enquiry form · castings and foundry
Enough to reply usefully, short enough that a buyer finishes it.
- Casting drawing or model
- The only basis for a real quote.
- Alloy and specification
- Determines feasibility.
- Annual volume and batch size
- Drives process and tooling choice.
- Pattern status
- Existing, transferring or new.
- Machining requirement
- As-cast or finished changes the quote entirely.
- Inspection and certification required
- Non-destructive testing needs planning and adds cost.

Questions suppliers ask
How do we win a casting transfer from another foundry?
By answering the pattern question before it is asked. State plainly how transferred patterns are received, inspected and refurbished, who owns them afterwards, and on what terms they can be released. The technical work is rarely the barrier; the tooling relationship is.
Should we publish our inspection equipment list?
Yes, with the equipment named. Castings are accepted on internal quality, and a buyer judging risk wants to know whether soundness is verified in-house or subcontracted. It is also one of the few genuinely differentiating things a foundry can publish.
Is simulation capability worth mentioning?
Yes, in plain terms — that solidification and feeding are modelled before the pattern is cut. Buyers who have suffered scrap from poor methoding understand exactly what it means, and it separates a foundry that engineers castings from one that pours them.
Documents and standards named here are the ones buyers in this industry commonly ask for; requirements vary by market, customer and contract, so treat this as a starting checklist rather than a compliance list.
