Step-by-step RFQ

A buyer-friendly RFQ workflow (NDA first)

1

NDA (if needed)

For sensitive programs, we can sign your NDA or provide ours before you share CAD and drawings.

2

Send drawing + model

Send 2D PDF and 3D STEP/IGES with revision level. If you have an assembly, include interface notes and critical features.

3

Define material + finish

Provide grade/condition and finish standard (anodize/passivation/plating/coating). If flexible, we can recommend options.

4

Quantity + schedule

Prototype vs production, target ship date, and any ramp plans. This impacts routing, fixture approach, and pricing.

5

Documentation requirements

Specify CoC, material certs (MTR), dimensional reports, and first-article package requirements. Also note any customer-specific formats.

6

Packaging + shipping

Labeling rules, serial/lot traceability, kitting BOMs, and surface protection requirements. Provide ship-to and incoterms if applicable.

What happens after you submit an RFQ

A quote is only useful if it is built on the same assumptions your receiving and engineering teams will use later. After we receive your package, SEMIX runs a structured review so the quote reflects reality—material availability, process route, inspection plan, and finishing boundaries.

  1. Contract review: confirm revision, quantities, CTQs, documentation requirements, and packaging expectations.
  2. Manufacturing route: determine clampings, datum strategy, and operations required (milling/turning/4‑axis/5‑axis, secondary ops).
  3. Inspection planning: define how CTQs will be verified (method, sampling logic, report format).
  4. Quote and options: we return price, lead time, and assumptions. If you have trade‑off flexibility (finish, material condition, inspection depth), we can provide alternates.

What we send back (quote package)

  • Price + lead time with clear assumptions (material, finish, inspection, packaging).
  • Open questions and required clarifications (so you don’t discover gaps during production).
  • DFM notes when geometry can be improved for cost, yield, or stability.
  • Documentation list showing what will ship with the parts (CoC, MTR, inspection report, finish certs).

Send your RFQ

Tell us what you need and attach drawings/models. We typically reply within 1 business day with questions and a quote timeline. If the upload is larger than 25MB, you can also email sales@semix.vn with a link (Google Drive/Dropbox).

If you need a sample CTQ report or dossier format, request an Evidence Pack in your notes.

Accepted: PDF, STEP, IGES, DXF/DWG, ZIP. Attach what you have — we can start NDA-first.

Maximum attached files are 25 MB. Please let us know if you need a ftp account.

RFQ package checklist (so the quote is accurate the first time)

Information that prevents re-quotes and mismatched expectations
Priority What to include Why it matters
Must 3D model (STEP/Parasolid) and/or 2D drawing with revision clearly identified Locks geometry and prevents quoting the wrong revision—one of the most common global supply chain failure modes.
Must Material spec: grade/condition (e.g., Al 6061‑T6, SS 304, Ti‑6Al‑4V) and any compliance notes Material condition changes machinability, distortion risk, and achievable finish/tolerance.
Must Quantity + program stage (prototype / pilot / production) and target delivery date Drives route decisions, setup amortization, and inspection depth.
Should CTQs called out (features that drive fit/function), plus mating conditions if relevant Focuses process and inspection planning on the characteristics that matter most.
Should Finish requirements (anodize/passivation/plating/coating) and cosmetic expectations Finishing boundaries affect lead time, cost, and acceptance criteria at receiving.
Should Inspection/reporting needs (CMM report, sampling plan, first‑article layout) Prevents approval delays and rework caused by missing evidence.
Optional Packaging/kitting instructions, labeling, part marking, and ship-to consolidation needs Reduces internal touch time and accelerates receiving/assembly.
Optional Target cost / alternates you will accept (material, finish, tolerance relaxations) Lets us propose options that improve lead time and total landed cost.

Cost drivers vs lead‑time drivers (a practical view)

Cost drivers
  • Complexity and number of clampings (more setups = more risk and touch time)
  • Material cost and machinability (tool wear, cycle time, scrap risk)
  • Inspection depth (CMM time can dominate for tight GD&T)
  • Finishing scope (masking, special handling, certification requirements)
  • Edge condition and cosmetic expectations (manual work content)
Lead‑time drivers
  • Material availability and certification lead time
  • External finishing queue time (anodize/passivation/plating)
  • Engineering clarification cycles (unclear CTQs, missing revisions)
  • Inspection capacity for approval packages (FAI / layouts)
  • Packaging/kitting complexity and consolidation requirements

Quote assumptions (how to avoid surprises)

  • Measurement conditions matter: datums, temperature state, and method can change pass/fail near tight limits.
  • Finish boundaries must be explicit: what is cosmetic vs functional, masking rules, and acceptance criteria.
  • Revision discipline reduces risk: update drawings/models through a single controlled channel and define effective dates.

Need an NDA?

If your design is sensitive, request an NDA before sharing detailed CAD. We can start with a high-level summary (part family, material, size envelope, quantity) while the NDA is in progress, then finalize the quote once the full package is received.

Email RFQ files to admin@semix.vn. For NDA-first requests, email admin@semix.vn. (Optional: set up rfq@semix.vn and sales@semix.vn aliases.)

When you do not have a complete drawing package yet

Early-stage projects often start with partial information. You can still get a useful budgetary quote if you provide:

  • A 3D model + a short list of critical dimensions (CTQs)
  • Target material family and any must-have properties (strength, corrosion, weight, temperature)
  • Quantity and timeline (even if approximate)
  • Notes on mating parts or functional interfaces (what must align, seal, or slide)

Once the drawing is released, we convert the budgetary quote into a production quote through contract review and inspection planning.

Change management (how to avoid “surprise re-quotes”)

  • One revision channel: control updates to drawings/models through a single owner and revision log.
  • Effective date: define which parts are built to which revision if a change occurs mid-order.
  • Approval characteristics: if CTQs change, confirm whether first-article evidence is required again.

Lead‑time critical path (what actually drives delivery)

Lead time is usually the sum of the slowest steps, not the average. Understanding the critical path helps you decide where to spend time (engineering clarification) and where to reduce risk (material availability, finishing boundaries, inspection scope).

Typical critical-path elements for machined part delivery
Step Why it becomes the bottleneck How to reduce risk
Material procurement Certified material and specific conditions can have long lead times Confirm alternates early; include acceptable equivalents if possible
Finishing External queues and unclear acceptance criteria cause delays Define standard/spec and masking rules; avoid late changes
Engineering clarifications Unclear CTQs or missing revisions trigger re-quotes Use the RFQ checklist; call out CTQs; confirm revision control
Inspection & approval packages Tight GD&T and first-article evidence requires planning and time Agree on inspection level and method during RFQ
Packaging / kitting Complex labeling, kitting, and consolidation adds touch time Provide clear packing instructions; standardize labeling

Prototype vs production RFQs (scope correctly)

  • Prototype / quick‑turn: prioritize speed and learning. Define CTQs, accept cosmetic flexibility where possible, and avoid over‑inspection on noncritical features.
  • Pilot: lock the process route and inspection method; align documentation expectations so receiving approves consistently.
  • Production: add forecast information, packaging standards, and change control requirements; confirm what triggers re‑approval (revision changes, CTQ changes).
