QC workflow

The closed-loop quality system a factory floor actually runs on

Detection is just the start. Seam takes you from a detected defect to a recorded decision, a corrective action, a traceable shipment, and a certificate in the buyer’s inbox.

Ten workflows, one platform

Everything past the detection box

01

Lot disposition + AQL

Turn a graded lot into a recorded accept / reject / rework / downgrade decision. Built-in ANSI/ASQ Z1.4 sampling tells the inspector the sample size and accept/reject numbers; every sign-off is an auditable record.

ANSI/ASQ Z1.44-point gradeAudit trail
02

Corrective actions (CAPA)

Close the loop on alerts and SPC breaches. Record the assignable cause, the action taken, an owner, a due date and effectiveness verification on a status-laned board.

03

Operator · machine · shift

Every inspection carries who ran it, on which machine, on which shift — so "which loom? which operator? which shift?" is one click, and run-drift becomes machine-specific.

04

Roll defect map

Plot every defect at its meter mark along the roll so the cutting room can plan markers around defects — and see the longest defect-free cut at a glance.

05

Model vs. human accuracy

A confusion matrix and per-class precision/recall built from your reviewers’ corrections — so you can trust the model exactly where it has earned it.

06

Customer specs

Define acceptance rules per customer — AQL, four-point limit, inspection level, and auto-reject defect classes — and every lot is graded against the right spec automatically.

07

Quality certificates

A branded, print-ready certificate of analysis per batch — grade, defect breakdown, AQL plan, disposition and sign-off — to forward to buyers at contract signing.

Andon wall display

A big-screen, auto-refreshing floor view: one tile per line, live defect rate against its control limit, green/amber/red status and a breach ETA.

09

Traceability + recall

Link every roll back to its supplier lot and forward to the customer PO. Search any link to scope a recall instantly: "which shipments contain supplier lot X?"

Predictive early-warning

Project the run’s defect trend forward and estimate how many units until the SPC limit is breached — act before producing bad fabric, not after.

Lot disposition

From grade to a recorded decision

Seam grades the lot with the four-point system, runs the Z1.4 sampling plan, checks for banned defects, and recommends a disposition — then the reviewer signs it off. Here’s a real reject from a problem supplier.

  • ANSI/ASQ Z1.4 sample size + accept/reject numbers
  • Spec-aware: graded against the customer’s acceptance rules
  • Every decision is an auditable, timestamped record

Roll defect map

Plan your cuts around the defects

Every defect placed at its meter mark along the roll, with the longest clear run highlighted — the same view the cutting room uses to lay markers.
