Batch Traceability: From Incoming Material to First Article, Production and Reorder

Acrylic-panelled enclosure line in production
Short answer: To trace an acrylic part from its sheet lot to the batch you received, use the part number and drawing revision as the key, and ask the supplier to link four records to it: the incoming material record (grade, thickness, sheet lot), the first-article result for that drawing revision, the dimensional and final inspection results, and any approved change. A drawing revision should trigger a new first article. Which of these records come with your order, and at what level — lot, batch or part — is agreed in the quotation.
AcrylicFabWorks is the acrylic division of SinoPlastix. We machine PMMA parts at one site in Suzhou, China, by default from Calypto cast acrylic sheet cast on our own line, so the sheet and the machining sit under one roof; Mitsubishi or Lucite optical-grade PMMA is used when the order specifies it.
What a traceability chain should connect
- Incoming material: grade, thickness and sheet lot, checked against the order
- Drawing review and the approved drawing revision
- First article against that revision
- Dimensional report on the flagged critical features
- Customer approval of the first article or sample
- Production and final inspection under an agreed sampling plan
- The batch record that ties the above to the order number and part number
- On reorder: a comparison against the approved first article and the same drawing revision
Reorders and lot-to-lot consistency
The usual cause of a reorder looking different is an unrecorded change — a different sheet source, a new drawing revision or a changed process. Ask that material, process and drawing changes be confirmed with you before production and recorded against the part number, so the new state is traceable.

Which traceability level fits your order
| Your situation | Ask for | Usually not needed when |
|---|---|---|
| You must trace parts back to a material lot | Material lot record or certificate tied to the order | Part-level evidence is enough |
| You reorder the same part regularly | Comparison against the approved first article and drawing revision | It is a one-off prototype |
| Your drawing revision changed | A new first article for the new revision | The reorder is unchanged |
| Your QA needs inspection evidence per batch | Dimensional report and final inspection record for the batch | A certificate of conformity alone is accepted |
What to put in the RFQ
- Part number and drawing revision
- Traceability level required: lot, batch or part
- Which records you need with the shipment, and whether redacted examples are needed before the purchase order
- Your change-notification requirement
FAQ
Can I trace a part number back to its material lot?
Ask for lot-level traceability in the RFQ; the quotation confirms which material record is linked to your order.
What should happen when the drawing revision changes?
A new first article against the new revision, with the change recorded against the part number.
Are batch records published online?
No. They are order-specific and are not published on this site.
Which records come with a production order?
The quotation lists them for your order; agree the set before the purchase order.
