Choosing a fabrication partner is a qualification exercise, and most qualification conversations fail the same way: the buyer asks general questions, gets confident general answers, and learns nothing. The fix is asking questions that only a well-run shop can answer specifically. Here are twelve, grouped the way procurement actually evaluates — capability, quality, schedule, and program management — with what a strong answer sounds like for each. They are worth asking of any fabricator, including this one; put them in your next RFQ and see what comes back.
Capability
1. Which operations are in-house, and which are brokered out?
Cutting, forming, printing, bonding, finishing — each step that leaves the building adds a handoff, a transit leg, and a second shop’s queue to your lead time, and blurs accountability when something is wrong. A strong answer names what is done in-house and is candid about what isn’t.
2. What happens to the schedule when a step is outsourced?
If a process is brokered, the partner should be able to say how that leg is scheduled and who owns the date. “It’s usually fine” is not an answer.
3. What materials and thicknesses do you actually run?
A shop that works acrylic alongside polycarbonate, PETG, and other sheet materials can advise on the material choice instead of defaulting to what’s on the rack. The acrylic-versus-polycarbonate decision alone changes guarding, glazing, and display projects.
Quality
4. How do you define an acceptable surface — is there a measurable standard, or an adjective?
This is the single most revealing question on the list. A weak answer is “we do high-quality work.” A strong answer names a criterion with units attached — for example, finish grades defined by inspection distance, the way the Acrylic Quality Standards fix Production Finish, Display Finish, and Museum Archival Finish to the distance at which cosmetic characteristics may become visible.
5. What tolerance do you hold — per process?
One blanket number is a red flag, because cutting methods differ: published ranges like laser-cut components at approximately ±1/32 inch to ±1/64 inch versus saw-cut work at approximately ±1/16 inch to ±1/8 inch, per the Acrylic Fabrication Tolerances standard, are what a per-process answer looks like. A shop that publishes its ranges has decided to be measured against them.
6. What does first-article approval look like?
For production runs, the first article is the reference every later part is compared to. A strong answer describes what gets checked — dimensions against process bands, finish on named surfaces, print against the approved proof — and how approval is recorded.
Schedule
7. When you commit a date, what mechanism backs it?
There is a real difference between a promise and reserved capacity. Under the Production Scheduling Standard, standard work is sequenced by available capacity, Accelerated Production moves a project forward when available capacity allows, and only Reserved Production — dedicated fabrication capacity allocated to the project — guarantees a specific manufacturing completion date. Whatever vocabulary a shop uses, it should be able to tell you which of its commitments are which.
8. How is time-critical work scheduled?
The follow-up to question 7: when your deadline is fixed and public, what does the shop actually do differently? A strong answer describes a mechanism, not an attitude.
9. What is your clarification process when a drawing has a gap?
Every project has at least one open question. You want a shop that asks early — at quote or file review — rather than guessing and letting the guess surface at delivery.
Program
10. How do you guarantee reorder consistency?
If this fixture works, you will order it again. A strong answer involves a record — locked drawings, approved proofs, retained program files — so that the reorder is a purchase order, not a reinvention.
11. How are revisions controlled?
Designs change. The question is whether a revision produces a new, identified drawing state that both sides quote and build against, or an email thread that someone has to reconstruct later.
12. How is our tooling, fixturing, and artwork handled?
Forms, jigs, and production art created for your program should be identified with your program — ask how they are stored, and what happens to them over time.
Scoring the answers
Across all twelve, the pattern to listen for is the same: strong answers are specific and measurable — named grades, published ranges, described mechanisms, identified records. Weak answers are adjectives and reassurance. No shop will be perfect on all twelve, and candor about a weak spot is itself a strong answer. The partner you want is the one whose answers you could write into a purchase order.
Ask us the same twelve — start with your next RFQ and hold the answers to the standard above.
