Meeting electrical steel suppliers at a trade show: how to prepare
A twenty-minute meeting at a booth is enough to qualify a supplier, if you bring the right information and ask the right questions.
With CWIEME Berlin in May and CWIEME Shanghai in June, spring is the busiest season for meeting core-material suppliers. Booth meetings are short, so preparation decides whether you leave with a usable quotation or just a brochure.
Bring
- Your grade, thickness and width requirements, or a drawing of the lamination or core.
- Annual volume and typical order size.
- Destination port and the Incoterm you normally buy on.
- The test frequency and flux density your design uses, so loss figures can be compared like for like.
Ask
- Which mill supplies the base material, and will each coil come with that mill’s certificate?
- What processing is done in-house, and what inspection report comes with each delivery?
- Can I see the plant, in person or by video?
- Which grades are available now in my thickness, and which depend on the next mill allocation?
Reading samples at the booth
Pick up a lamination or a core and look at the edges against the light: a clean, even cut with little burr shows sharp tooling and correct clearance. On a stacked core, the faces should be flat and the outline should line up without steps. On coated parts, the coating should be even and should not flake at the edges. None of this replaces a test, but it tells you quickly whether a supplier is worth testing.
If you can, ask for the mill certificate of the coil the sample was made from. A supplier who can produce it at the booth or within a day usually runs real traceability on the shop floor.
Warning signs
- Loss figures quoted without the test condition or the standard.
- Reluctance to name the mill or to show a certificate.
- Prices far below the mill price for the same grade.
Write short notes after each meeting, before the next one starts. After ten booths, the details run together, and the notes are what let you compare suppliers fairly once you are back at your desk: who named the mill, who offered a certificate, who could show a sample from the grade you need.
After the show
Send a short summary of what was agreed within a week, while it is fresh on both sides, and ask for samples or a quotation against your written specification. A good supplier will answer with the grade, the mill, the processing route and the documents you will receive.
Our answers: Baosteel material with the Baosteel certificate, in-house slitting, cutting and stamping, an inspection report with every delivery, and plant or video visits on request. If we do not meet at a show, the same conversation works by email or video call.
