OEM Plastic Zipper Assembling Line Machinery Supplier
This page describes the modular assembly line equipment designed for the production of plastic coil zippers. It outlines the technical parameters, functional capabilities, and integration considerations relevant to OEM manufacturers.
System Overview
The line consists of sequentially arranged stations: monomer feeding, tooth formation, tape attachment, winding, and optional inspection. Each station is driven by synchronized servo motors to maintain precise pitch control. Modular construction allows the total number of stations to be adjusted according to required zipper width and output rate.
Typical line speed reaches up to 150 m/min with a positioning repeatability of ±0.02 mm. Electrical supply is three‑phase 380 V 50/60 Hz, and compressed air at 0.6 MPa powers pneumatic actuators for tool changes.

Key Functional Characteristics
These characteristics directly influence product yield, changeover time, and maintenance intervals.
- Servo‑driven tooth molding with torque feedback for consistent profile
- Precise tape tension control using closed‑loop dancer system
- Automatic length measurement and cut‑off with laser encoder
- Quick‑change tooling system allowing size swap in under 5 minutes
- Integrated vision inspection for missing teeth and tape misalignment
Typical Applications in Zipper Production
Plastic coil zippers are used in garments, luggage, sports equipment, and outdoor gear where flexibility and corrosion resistance are required. The line accommodates tape widths from 2 mm to 5 mm and can produce invisible, conventional, and waterproof tooth profiles by swapping molding inserts. Continuous operation minimizes batch changeover losses compared with semi‑automatic presses.
Customization and Integration Options
Options are selected based on plant layout, product mix, and data‑traceability needs.
- Adjustable station spacing to accommodate varying zipper lengths
- Optional laser marking module for brand logos or lot codes
- MES‑compatible data logging interface (OPC UA)
- Retrofit kit for integrating with existing conveyor systems
- Safety guarding configurations meeting ISO 13849‑1 PL e
Quality Control and Validation Approach
In‑process monitoring includes torque feedback from each servo drive and real‑time vision analysis of tooth geometry. Finished zippers undergo tensile strength testing (≥ 15 N per tooth) and pull‑off force verification. Calibration of measurement equipment is traceable to national standards, and a statistical process control chart tracks key dimensions per shift.
Frequently Asked Questions
- Can the line be adapted for different zipper sizes?
Yes, station spacing and molding inserts are adjustable; a full size change typically requires < 30 minutes. - What information is needed for a quotation?
Required inputs include target zipper width, tape material, desired output rate, and any special features such as waterproof coating or laser marking. - Which materials are compatible with the molding stations?
The process works with standard POM, PET, and PP granules; material flow rates are adjusted via the feeding hopper. - How is quality inspected during production?
Each station provides torque feedback; a vision system checks tooth presence and tape alignment at 100 % line speed; statistical sampling validates dimensions. - What packaging options are available for shipment?
Machines are shipped in sealed, shock‑absorbing crates with optional corrosion‑inhibiting film; dimensions are provided per order.
