The short answer
Most machining RFQs get ignored for boring reasons: bad package, vague demand, unrealistic timing, or a part that does not fit the supplier's sweet spot.
Why shops stay silent
Suppliers ignore RFQs when the package is incomplete, the geometry looks risky, the volume is unclear, or the customer appears likely to argue about every revision. Shops also ignore work that is obviously outside their niche but not stated clearly enough to decline quickly.
Silence is usually a filtering mechanism, not a mystery.
What a responsive RFQ looks like
A clean RFQ has revision-controlled files, quantity, forecast if known, material, finish, required reports, target timing, and a short note on what matters most: speed, price, quality package, or domestic source. That lets the supplier decide quickly whether to engage.
Buyers who hide demand profile or quality requirements create their own low response rate.
What to fix first
Make the email subject clear. Put the due date, quantity, and process clues in the body. Name the attachment revisions. Ask for a yes or no if the supplier cannot quote. And stop sending ten unrelated parts to a shop that only likes one of them.
Supplier fit is a response-rate issue as much as email quality.
A harsh but useful rule
If your RFQ would force you to ask three clarification questions before quoting, it deserves a low response rate. Fix the package first, then blame the market.
The market is not obligated to decode lazy RFQs.

The right move is usually to define the real functional requirement, remove the decorative requirements, and let the supplier build a route around what actually matters.
Comparison table where relevant
| Problem | What the shop sees | Fix |
|---|---|---|
| No quantity or forecast | No idea how to route the job | State lot size and annual use |
| Missing material/finish | Quote risk | Specify exact material and finish |
| Unrealistic timing | Likely time waste | Give honest due dates |
| Bad supplier fit | Outside capability or appetite | Target the right shops |
How to specify this in your RFQ
Put revision, quantity, material, finish, cert requirements, and quote due date in the email body. Ask suppliers to confirm fit fast, even if they decline. That one line improves response rate because it lowers the burden of saying no.
A clean RFQ does not just list requirements. It separates must-haves from preferences so the supplier can optimize where it is safe.
