Wireform RFQ checklist: 14 things to send
A formed wire part is quoted from the drawing, the wire call and the volume. Leave one out and the supplier will fill the gap with an assumption that you pay for later.
Topic hub
Formed wire looks simple until a bend radius, a temper or a load test decides whether the part works. These guides cover the drawing calls that matter, the process limits behind them and the questions to ask before a quote.

What a tier one or OEM programme expects from a formed wire part, and the records that have to survive the first year of production.
Material and coating choices for wire parts that live in wet, vibrating air paths, and the contact points where both failures start.
What a buyer needs to send, what tooling actually covers, how volume changes the route and where the cost sits between quote and first shipment.
A compact audit script for buyers: the questions that separate a forming shop from a trader, and the records that prove the answers.
Four practical routes for small wireform batches, what each one is good for, and how to write an RFQ that a supplier can price without building a production tool.
Spring index links stress, rate, tolerance and tooling in one number. Here is why the practical band runs from 4 to 12, and what to change when a design falls outside it.
