Toleranzen bei kundenspezifischer Drahtgeflecht-Fertigung, die Käufer bestätigen sollten

Englischer Originalleitfaden

Custom mesh parts fail when tolerance logic is not defined

Buyers often send drawings for baskets, guards, discs, panels, trays, or formed parts without clearly identifying which dimensions are critical. Suppliers can manufacture the part, but disputes appear later if the RFQ does not distinguish cosmetic dimensions from fit-critical tolerances.

Different fabrication steps introduce different variation

Cutting, shearing, bending, spot welding, rolling, edging, and frame assembly each add their own tolerance stack. A woven mesh panel with formed edges will not hold the same dimensional behavior as a laser-cut sheet component. Buyers should align realistic tolerances to the actual process route.

Approve samples against a measurement plan

• Mark critical dimensions, datum references, and inspection points on the drawing.
• Confirm whether flatness, squareness, and weld marks are acceptance items.
• Ask how packaging protects formed geometry during export.

Clear tolerance agreements reduce claim risk, shorten sampling rounds, and improve repeat-order consistency.
