Parts Feeding RFQ Checklist 2026

A good RFQ saves weeks

Many feeder projects slow down before they start because the RFQ is too thin. A buyer asks for a bowl feeder quote, sends one photo, and waits for a meaningful answer. The supplier answers with a broad price range because that is all they can honestly do. Then both sides lose time clarifying the same basics that should have been defined on day one.

A parts-feeding RFQ does not need to be perfect, but it does need to be specific enough for engineering to make the right first decision. The supplier needs to know the part, the rate, the presentation requirement, and the operating conditions. Without that, the quotation is only a placeholder.

This guide lists the information that helps most. If your project is still at the budgeting stage, it pairs well with our price guide and custom automation buying guide.

The 15 items a supplier should receive

Below is the short list that usually makes the biggest difference. Not every project needs every item in the same depth, but skipping several of them almost always leads to rework at quotation stage.

1. Part drawing or 3D file. The supplier needs dimensions, tolerances, and shape, not just a verbal description.
2. Real production samples. Surface finish, oil, burrs, and lot variation show up here.
3. Target output. Give the required good-part rate, not a rough estimate.
4. Output orientation. Define exactly how the part must leave the feeder.
5. Part material and finish. Stainless, plated steel, molded plastic, coated, polished, and so on.
6. Part weight and size range. This affects bowl size and drive selection.
7. Expected lot variation. If the part comes from more than one supplier, say so.
8. Working environment. Cleanroom, washdown, oily shop floor, ESD area, and temperature constraints all matter.
9. Runtime expectation. State whether the line needs 30 minutes or 4 hours of unattended operation.
10. Available footprint and height. Many good designs fail because the machine base cannot accept them.
11. Power and controls preference. 110 V or 220 V, analog or digital controller, PLC integration, protocol needs.
12. Downstream interface. Escapement, robot pick, screwdriver, conveyor, or direct handoff.
13. Changeover frequency. One part forever is very different from weekly SKU changes.
14. Quality requirements. Cosmetic protection, orientation error tolerance, and reject handling.
15. Project timing. Needed delivery date, FAT expectation, and shipment destination.

Why RFQs go wrong

The most common problem is assuming a feeder is generic. It is not. Feeding performance depends on the real part and the real line. Another issue is mixing purchasing language and engineering language. Purchasing may ask for three quotes quickly, while engineering still has not defined the output orientation or the shift runtime. That creates pricing noise, not useful comparison.

Another common error is sending ideal data without the bad news. If the part is oily, scratched easily, or varies from lot to lot, include that early. Hiding those issues does not create a lower-cost feeder. It creates a more fragile quote.

How to compare the quotes you receive

Do not compare by price alone. Compare by scope, by assumptions, and by how clearly the supplier explains the feeder concept. A low quote that ignores the hopper, controls, changeover, or FAT requirements is not a low-cost project. It is a partial project.

Pay attention to whether the supplier asks follow-up questions. In feeder work, thoughtful questions are usually a good sign. They mean the supplier is trying to reduce risk before build instead of pushing that risk into your factory later.

Also check whether the quotation reflects your actual plant conditions. If you mentioned ESD, washdown, or cosmetic protection and the quote does not address them, you do not yet have a complete answer.

What Huben usually needs to quote accurately

For most parts-feeding RFQs, Huben Automation can move much faster once the team receives the part sample, output orientation, target ppm, runtime goal, and any special environment note such as cleanroom, ESD, or washdown. If the project involves robot picking or a custom assembly machine, then interface and controls information become just as important.

That does not mean buyers need a perfect specification package before first contact. It only means the closer the RFQ gets to the real production case, the faster the project moves from broad pricing to a credible feeder concept. If you want a quick engineering review before formal quotation, send us the sample, drawing, and target rate and we can help you tighten the RFQ.
