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):
30+ defect types including missing code, tape damage, shrunk teeth
Inspection accuracy 0.1 mm
Real-time feedback and reject sorting linkage

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).
Synced with assembly station cycle; in-process rejection and traceability
③Tape gluing & punching
Tape gluing & punching inspection module
Glue position, width, overflow; hole offset
Missing holes, burrs, tape damage
④Slider insertion
Slider insertion inspection module
Slider presence, orientation, damage
Synced with machine cycle; alarm/stop linkage
⑤Top/bottom stop injection
Top/bottom stop injection inspection module
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
Smart Inspection Slider Insertion Machine
Complete machine
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
Smart Inspection Slider Sorting Machine
Complete machine
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
Contact us with samples and line video for on-site assessment, design, and trial inspection.
