China Stirrup Bender Manufacturers: Drawing Revision Control

Quick answer: When ordering a stirrup bender from a Chinese manufacturer, give every production drawing a revision number and agree which revision the quotation and factory trial cover. A clear change record prevents the wrong shape from becoming the acceptance sample.

Create one approved drawing set

A drawing set should identify the part name, revision, units, steel grade, bar diameter and required dimensions. Put the document date and the buyer’s approval on the same record. If several departments send files, nominate one person to approve the final set so the manufacturer does not receive competing instructions.

Separate a clarification from a design change

A clearer scan of the same drawing is different from a new bend radius or changed bar grade. Ask the manufacturer to confirm whether a change affects tooling, feeding settings, programming, price or delivery. Keep the earlier revision for traceability and mark it superseded rather than silently replacing it.

Connect the quote, program and sample

Use the same drawing identifier in the written quotation, trial request and sample inspection sheet. During a demonstration, ask which program and tooling correspond to that identifier. A video showing an unidentified stirrup cannot establish that the quoted configuration has processed the buyer’s revised design.

A practical approval record

Record four items together: approved drawing revision; manufacturer’s compatibility response; agreed test conditions; and buyer’s acceptance decision. For a mixed order, list every shape that is essential. This is a procurement workflow example, not a claim that a particular configuration will make every reinforcement shape.

Questions for the manufacturer

Can a drawing change affect delivery?

It can, particularly if it changes tooling, material requirements or the trial scope. Ask the manufacturer to confirm the effect before approving the revision.

What should I send Haihui?

Send the approved drawings, revision list, material specification and required production task. Identify which dimensions are critical to your application.
