Case Metrics
Finished Zipper Inspection Equipment
1. Overview
Smart QC for the final cutting & packaging stage of zipper production. Multiple configurations inspect nylon, metal, and resin zippers before or after cutting.
Flexible complete-machine options:
- Smart cut-and-inspect machine—integrated cutting + AI inspection
- Cut-pack-inspect all-in-one—cut, QC, count, and packaging linked
- Smart inspection labeling machine—label only; mounts before existing cutters for fast vision upgrades
2. Detectable Defects
The system detects 30+ common defects across teeth, tape, sliders, and cut positioning (nylon / metal / resin; model-dependent):
Teeth
- Missing, damaged, skewed, shrunk teeth
- Misalignment, burrs, tooth defects
- Poor engagement, height mismatch
Tape / appearance
- Tape tear, stain, scratch
- Color variance, wrinkle, weave anomaly
- Poor sealing, edge burr
Marking / length
- Missing/mixed/wrong marks
- Length out of spec, cut offset
- Sorting/count errors
Slider / parts
- Missing, reversed, damaged slider
- Missing/misplaced top/bottom stops
- Poor pin/box fit
Miss rate below 0.01%; auto reject and count; up to ~40 pcs/min depending on spec and model.

In-Process Zipper Inspection Modules / Equipment
1. Overview
In-process vision QC at key zipper manufacturing stages—from metering (tooth)/sewing, tape gluing & punching, and slider insertion to top/bottom stop injection—to catch defects mid-process.
2. Products & Solutions
For key in-process stations, JND offers inspection modules (retrofit to existing machines) and complete machines (inspection integrated with process actions) for mid-line rejection, marking, traceability, and closed-loop QC data.
Inspection modules
AI vision modules embed at key stations along the zipper line for in-process rejection and traceability. The flow below shows typical stations and matching inspection solutions (stations can be added or removed per your process).
- Tooth spacing, missing teeth, sewing defects
- Synced with machine cycle; stable, traceable QC
- Glue position, width, overflow; hole offset
- Missing holes, burrs, tape damage
- Slider presence, orientation, damage
- Synced with machine cycle; alarm/stop linkage
- Stop appearance, position, defects online
- Misalignment, missing, flash; alarm and data logging
Complete machines
For marking, slider insertion, slider sorting, and other typical in-process stations, JND provides complete-machine solutions that integrate inspection with process actions—ready to deploy with matched cycle time.
- Marking, AI vision inspection, and labeling integrated for in-process QC and identification
- Detects missing/mixed/wrong marks and zipper appearance defects in one pass
- Synced with line cycle; alarm linkage and traceability
- Slider insertion and AI vision inspection in one machine
- Online check for slider presence, orientation, and damage
- Real-time alarm and stop linkage to reduce downstream defects
- Slider vision inspection and automatic sorting integrated
- Identifies appearance, size, orientation defects and sorts rejects
- Improves slider feeding quality and cuts manual re-inspection
For other stations or special machines, we offer station-level vision solutions with custom mounting and MES/PLC integration for closed-loop QC data.
Combine in-process and finished-goods inspection to cut returns and rework.
Custom Solutions
Beyond standard models, we offer end-to-end customization by line layout, zipper type (nylon / metal / resin), station (in-process / finished, pre/post cut), and MES/ERP integration:
- Station fit—modules for cutters, packers, slider machines, conveyors
- Algorithm—train on your SKU library; ~19 s setup, ~5 min changeover
- Mechanical—loading, flip, divert, reject paths per layout
- Data—reports, batch traceability, factory IT integration
