B2B Plastic Zipper Tooth Forming Machine
This machine forms plastic zipper teeth by melting thermoplastic resin and injecting it into precision molds that shape the tooth profile.
It operates continuously, delivering a stream of formed teeth that can be directly fed to zipper tape assembly lines.
Technical Specifications
Key performance parameters are presented below; values vary according to model selection and material characteristics.
| Parameter | Typical Value | Notes |
|---|---|---|

| Max tooth width | 8 mm | Adjustable via die set |
| Max tooth height | 4 mm | Depends on material shrinkage |
| Production speed | Up to 250 teeth/min | Limited by cooling capacity |
| Motor power | 7.5 kW | Main drive |
| Control system | PLC with HMI | Recipe storage |
| Heating method | Electric barrel heaters | Zoned temperature control |
| Footprint (L×W×H) | 1800 mm × 900 mm × 1500 mm | Includes control cabinet |

These specifications enable engineers to calculate line throughput and required floor space for integration.
Applications
In apparel manufacturing, consistent tooth geometry ensures smooth slider movement and reduces fastening failures.
Industrial sectors such as automotive upholstery and sports equipment rely on the same tooth precision for durable closures.
Customization Options
Manufacturers adapt the forming machine to specific zipper designs by changing die geometry and processing parameters.
- Die width adjustment from 3 mm to 8 mm
- Interchangeable tooth profiles (standard, reverse, concealed)
- Variable feed rate up to 200 teeth/min
- Temperature zones with independent control (±2 °C)
- Optional pneumatic ejection for delicate materials
Quality Control
Inline laser gauges measure tooth width and height at a sampling rate of 100 Hz, feeding data to the PLC for real‑time adjustment.
Periodic sampling with a coordinate measuring machine validates long‑term dimensional stability.
Frequently Asked Questions
Can the machine be configured for different thermoplastic materials?
Yes, barrel screws and temperature profiles can be swapped to process materials such as POM, PP, or TPU, depending on melt flow characteristics.
What information is required to obtain a quotation?
Provide target tooth dimensions, desired production speed, material type, and any required auxiliary equipment (e.g., cooling conveyor).
How is machine installation supported?
The supplier supplies foundation drawings, electrical schematics, and commissioning guidance; on‑site training is available upon request.
What maintenance intervals are recommended?
Lubrication of moving parts every 500 operating hours, barrel cleaning when changing materials, and annual calibration of measurement sensors.
