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.

What does a buyer check before placing a casting with a new foundry?

Illustrative. The question is real; it is the one this guide answers.

What buyers check in metals and metalworking

Non-destructive test report

Conformity to the casting drawing

Dimensional inspection report

Asked at: first article and on request

Every claim on a supplier site has a document behind it or it does not. Buyers in castings and foundry know which is which.

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. 1

    Alloys poured

    The first filter, and often a hard one.

  2. 2

    Casting process

    Sand, investment, die and centrifugal casting produce different parts.

  3. 3

    Weight and size range

    A direct yes-or-no on the buyer's part.

  4. 4

    Annual tonnage and volume band

    Prototype, low volume and series suit different foundries.

  5. 5

    Machining capability

    Whether you supply as-cast or finish-machined.

  6. 6

    Pattern and tooling ownership

    The question that decides whether a transfer is possible.

  7. 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.

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

Is one of them you?

Illustrative. The documents are the ones buyers in this industry ask for.

What Plact does for metals and metalworking suppliers

Four jobs, done on your site. Each one is a document buyers in this industry already ask for.

  1. Put the ISO 9001 or sector certification on the page buyers check

    Quality system, plus automotive or pressure certification where relevant

  2. Put the Pattern ownership terms on the page buyers check

    Who owns the pattern and what happens at end of life

  3. Name the First article inspection and share it on request

    Full verification before series production begins

  4. Name the Simulation or methoding capability and share it on request

    That solidification is engineered rather than guessed

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. Clearer pages can help discovery and evaluation. They do not guarantee rankings, AI citations, enquiries or revenue.
