Most delays in a stamping quote come from one missing input. The supplier sends a question, waits for an answer, and the clock runs. Send these together and the first reply can be a real quote.
1. The part, in a form the tool designer can use
A 3D model (STEP or IGES) shows the shape; the 2D drawing shows what matters - tolerances, datums, critical holes and surface classes. Send both. If only a PDF exists, say so.
2. Material, grade and thickness
The grade and thickness set the press tonnage, the die design and the scrap rate. Name the standard you buy to, and say if the coil is coated.
3. Volumes and dates
Annual volume decides between a progressive die and stage tools. The SOP date decides whether the tool room can build in time. The date you need the quote by tells the supplier how to plan the estimate.
4. Tooling
Say whether tooling exists. If it does, say where it is and who owns it. Moving a tool is a different quote from building one.
5. Confidentiality
If the drawings need an NDA first, say so up front and send a description only.
