What Information Should I Send to Get an Accurate Sheet Metal Fabrication Quote?

Direct answer: For an engineering-based sheet-metal RFQ, send the drawing or 3D model, material and grade, quantity, critical tolerances, surface treatment, packaging, and delivery requirements. Complete inputs reduce assumptions; this page is the RFQ materials checklist, while the quote guide explains how the supplier reviews those inputs and the comparison page helps compare resulting scopes.

What missing information affects

FAQ

What should I send first? Send the latest drawing or model together with material, quantity, critical tolerances, finish, packaging, and delivery context.

Why do missing details change a quote? Missing inputs require assumptions about process, material, inspection, finishing, or logistics.

How is this different from the quote guide? This page is the RFQ submission checklist; the quote guide explains engineering review, and the comparison page helps normalize supplier scopes.

Use the quote guide, the quote comparison page, and the contact page. Inquiries are answered within 2 hours.

The distance between a rough estimate and a fabrication quote you can hold us to is mostly the information you send. Also, a complete package lets our engineers price the part instead of guessing, and every missing field becomes an assumption buried in the price. Overall, this page walks through the six fields, the file formats that protect them, and how fast the reply arrives.

How to get an accurate fabrication quote

Q1. What information makes the quote accurate?

A full quote request carries six pieces of information: the 3D model or 2D drawing, the material grade, the quantity, the surface finish, the tolerance callouts, and the target delivery date. Missing details force assumptions, and assumptions move the price. Moreover, the more precisely you describe the part, the closer the fabrication quote matches the final invoice. If the drawing does not carry tolerances, say which dimensions are critical — that single note prevents the most common re-quote later on.

Q2. Which file formats protect the fabrication quote?

Before anything else, send the drawing in PDF, STEP, or IGES format. These formats let our engineers review geometry, tolerances, and manufacturability directly. Specifically, a STEP file is the strongest choice when the price must survive a design change: it keeps the full 3D geometry, so the number you receive stays tied to the model you sent.

Q3. Why does quantity matter for the quotation?

Because volume changes the process choice, state the annual or total quantity. A small batch may follow a different route than high-volume production, and the fabrication quote depends on that route. Tooling cost, setup time, and the press schedule all sit differently at the low end, and that difference is what volume pricing is for. If you do not know the exact number yet, give a realistic range — a quote built on your range stays valid across it, and the per-part price at each point can be itemized.

Q4. How fast will I receive the quotation?

Our engineers review the geometry before quoting and flag tolerance, tooling, and finishing risks in a free DFM review. We respond to inquiries within 2 hours. Then, our engineers confirm the timeline for your fabrication quote in that first reply. That reply is where a missing drawing note or an unclear finish gets clarified — answer it once, and the price is settled.

Before you write that email, our sheet metal fabrication quote guide lists exactly which information keeps the pricing accurate.

Send your drawing with the five fields — material grade, quantity, finish, tolerances, delivery date — to tylor@xinjiuxinji.com. and the DFM review comes with the first reply. Besides the direct email above, our metal fabrication RFQ checklist lists every field that keeps the price accurate. Finally, message us directly on WhatsApp if you need a faster channel.
