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 for various defects.
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 machine—inspection only, no cutting; connects to third-party cutters; cutter OEM must update the interface program
2. Detectable Defects
The system detects 30+ common defects across teeth, tape, sliders, and parts (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
Slider
- Missing, reversed, damaged slider; paint loss; mixed types
- Pull tab defect, paint loss, mixed types
Parts
- Missing/damaged/misplaced top/bottom stops; exposed teeth; excess material
- Missing pin; tooth displacement; missing pin punch hole
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 Teeth moulding/sewing, chain zipper assembly, 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 teeth moulding / sewing machine cycle; stable, traceable QC
- Tape and tooth defects on chain zippers
- Synced with assembly station cycle; in-process rejection and traceability
- 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 typical processes such as chain zipper assembly, slider insertion, and slider sorting, Jingduo provides integrated machine solutions that combine inspection with process actions. Ready to use right out of the box and perfectly synchronized in cycle time, these machines allow for rapid integration into your production line.
- Chain zipper assembly, AI vision inspection, and labeling integrated for in-process QC and identification
- Synchronized detection of tape and tooth defects on chain zippers
- 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
