Plastic Zipper Hole Punching Machine Introduction     

The Auto Delrin Plastic Zipper Hole Punching Machine (Model HTD-PP03) is a specialized piece of equipment designed for the open-end zipper production line. Its primary function is to punch precise holes on plastic zipper tape after the film sealing (tape welding) process and before the insertion of pin boxes (sliders and stops) .

This machine features a specialized four-small-hole punching design – punching four small holes at specific positions on the zipper tape. These holes are critical for securing the pin box (Injection plastic insert at the zipper's open end), ensuring that the finished open-end zipper has strong pull resistance and long-term durability.

The HTD-PP03 is specifically engineered for Delrin, resin, and Vislon ,plastic zipper chains, and is an indispensable step in any automated open-end zipper production line.

Plastic Zipper Hole Punching Machine Working Principle & Process Flow      

The HTD-PP03 operates as a critical station in the open-end zipper production line:

Film Sealing – The zipper tape first passes through a film sealing/welding machine (such as the HTD-PW02) to apply reinforcing tape.

Hole Punching – The reinforced zipper tape enters the HTD-PP03, where the four-small-hole punching mechanism precisely creates holes at designated positions.

Pin Box Insertion – The punched holes serve as anchor points for inserting and securing the pin box (slider stop), completing the open-end zipper assembly.

This sequential process ensures that the pin box is firmly attached, preventing detachment and ensuring the zipper's long-term reliability.

Plastic Zipper Hole Punching Machine Application Scenarios   

The hole punching machine is a core process step in open-end zipper manufacturing:

Open-end zipper production – punching four small holes for pin box anchoring after film sealing

Garment manufacturing – jackets, coats, sportswear, and other apparel

Luggage & handbags – backpacks, suitcases, travel bags

Footwear – shoes and boots requiring durable zippers

Outdoor equipment – tents, sleeping bags, and other high-durability applications

It is typically used together with zipper gapping machines, film sealing/welding machines, and pin box inserters to form a complete automated open-end zipper production line.

1. Specialized Four-Small-Hole Punching Design

The HTD-PP03 is engineered with a specialized four-small-hole punching mechanism. This unique design creates four precisely positioned small holes that securely anchor the pin box, preventing it from loosening or falling off during repeated use – a critical requirement for high-quality open-end zippers.

2. Perfect Welding & Water Resistance

The punching process is combined with perfect welding technology, ensuring that the punched holes are clean, burr-free, and resistant to water penetration. This prevents the pin box from loosening or detaching over time, even under wet or high-stress conditions.

3. High-Speed Output

With an average output of 2,500 pieces per hour (based on 60 cm length), and a maximum capacity of up to 4,000 pieces per hour, the HTD-PP03 delivers exceptional productivity for high-volume manufacturing environments.

4. Wide Compatibility

Supports plastic zipper teeth from size #3 to #30, covering the full range of sizes used in garments, luggage, footwear, and outdoor gear.

5. Robust & Reliable Construction

Built with a sturdy mechanical structure, the machine is designed for continuous, heavy-duty operation. Core components include PLC, engine, and motor, ensuring stable performance and easy maintenance.

6. Complete Safety Protection

Equipped with a high-quality safety cover and door protection system, the machine complies with modern factory safety standards.
