Short answer:<\/strong> A complete metal stamping drawing package should include the controlled 2D drawing, 3D model if available, revision level, material grade and thickness, finish, tolerance notes, burr direction, critical features, assembly use, inspection requirements, packaging needs, annual volume, and target timing. Missing data usually turns into quote assumptions, delays, or cost changes after tooling review.<\/p>\n

Many quote delays are not caused by supplier capacity. They happen because the RFQ package leaves too much for the supplier to guess. A stamping supplier can estimate tooling and unit price faster when the drawing package separates fixed requirements from open decisions.<\/p>\n

Use this checklist with the drawing review checklist<\/a>, quote assumptions checklist<\/a>, RFQ checklist<\/a>, and DFM review before tooling guide<\/a>.<\/p>\n

Package item<\/th>\nWhy it matters<\/th>\nWhat to send<\/th>\n<\/tr>\n<\/thead>\n
Controlled drawing<\/td>\nThe 2D drawing is the quote authority for tolerance, revision, and notes.<\/td>\nPDF plus native CAD if allowed, revision, release date, and drawing owner.<\/td>\n<\/tr>\n
3D model<\/td>\nFormed features and assembly clearances are easier to review in 3D.<\/td>\nSTEP, Parasolid, or other neutral file tied to the same revision.<\/td>\n<\/tr>\n

Mark what is fixed and what can be reviewed<\/h2>\n

A supplier can help with manufacturability only when the RFQ shows which requirements are fixed. Material grade, thickness, finish, assembly interface, and safety-critical dimensions may be locked. Hole size, bend radius, burr side, packaging, or inspection sample size may still be open for DFM review.<\/p>\n

If a part has previous supplier problems, include the failure history instead of only sending a clean drawing. Burr complaints, late tool changes, mixed revisions, plating stains, or poor flatness tell the supplier where to focus review. For risk planning, connect the package to the supplier risk matrix<\/a> and critical dimensions inspection plan<\/a>.<\/p>\n

Keep the file revision trail clear<\/h2>\n

Do not send a PDF, STEP file, and sample photo if they show different revisions without explanation. The supplier may quote the wrong geometry or build tooling to the wrong feature set. If files are mixed because the latest 3D model is not available, state which file controls each decision.<\/p>\n

A controlled file list should include file name, revision, date, and whether the file is for quote only, tooling, inspection, or packaging. This is especially useful when purchasing, engineering, and quality each send documents separately.<\/p>\n
