Wholesale Metal Zip Chain Making Machine

The machine forms continuous metal zip chains by feeding strip material through a series of progressive dies that cut, bend, and interlock each link in a single pass.

Designed for high‑volume production, the line integrates a servo‑driven feed, a pneumatic clamping station, and a programmable logic controller that stores up to 50 chain profiles.

Typical output reaches 120 m/min with a wire diameter range of 0.8–2.5 mm, making it suitable for both light‑duty and heavy‑duty zipper chains.

Technical Specifications

Values shown are typical; each parameter can be adjusted to match specific project requirements.

Operating Principle

A servo‑controlled feeder advances the metal strip into the first die station where a punch cuts the blank to length.

The blank then moves to a bending station that forms the characteristic “S” shape of a zip link; a synchronized pneumatic clamp holds the part while a second die creates the interlocking hook.

Because each station is driven by independent servo axes, the pitch, hook depth, and link height are programmable without mechanical change‑over.

Industrial Applications

The equipment serves sectors where repeatable, high‑strength zip chains are critical for product integrity.

• Automotive seating – chains endure constant tension and vibration; the machine’s precise pitch control ensures consistent load distribution.
• Luggage and bags – rapid change‑over allows manufacturers to switch between decorative and heavy‑duty chain profiles on the same line.
• Industrial fasteners – the ability to process stainless‑steel and coated wires meets corrosion‑resistance specifications.
• Medical device packaging – clean‑room compatible finishes and tight dimensional tolerances support sterile barrier requirements.

Customization Options

• Chain pitch and link geometry – fully programmable via HMI.
• Material grade – carbon steel, stainless 304/316, alloy steel, or customer‑specified alloy.
• Surface treatment – zinc plating, nickel plating, epoxy coating, or passivation.
• Control interface – standard PLC/HMI, optional EtherCAT, Profinet, or OPC UA for plant integration.
• Safety guarding – light curtains, interlocked doors, or full enclosure per CE/UL requirements.

Quality Assurance

Each machine undergoes a multi‑stage inspection before shipment: dimensional verification of critical die clearances using calibrated CMM, tensile testing of sample chains to confirm minimum break load, surface‑finish measurement per Ra specification, and a 30‑minute run‑in at rated speed to verify thermal stability.

Documentation includes a factory acceptance test report, material certificates, and a conformity declaration aligned with ISO 9001 quality management practices.

Packaging & Shipping

Units are secured in fumigated wooden crates with internal steel bracing; vibration‑absorbing foam protects the servo drives and HMI.

A shock‑indicator label and humidity‑controlled desiccant packs are included; containers are loaded with the machine’s center of gravity centered to minimize transit stress.

Standard Incoterms offered: EXW, FOB, CIF; alternative terms available upon request.

Frequently Asked Questions

Can the chain pitch be changed after installation?

Yes, the servo‑driven feed and programmable die positions allow pitch adjustments without mechanical tooling changes.

What information is required for a quotation?

Provide desired chain width, wire diameter, material grade, production volume, and any special surface‑finish or safety‑standard requirements.

Which materials can be processed?

Carbon steel, stainless 304/316, alloy steels, and most non‑ferrous alloys up to 2.5 mm diameter; other grades evaluated case by case.

How is quality inspected before delivery?

Factory acceptance testing covers dimensional accuracy, tensile strength, surface finish, and a 30‑minute run‑in at rated speed; full report supplied.

What packaging options are available for export?

Standard fumigated wooden crate with foam bracing, shock indicator, desiccant; custom crating or container loading plans on request.

What is the typical production lead time?

6–10 weeks from order confirmation, depending on customization level and current order backlog.

How are samples arranged?

Sample chains can be produced on a pilot machine; shipping cost and lead time quoted separately.
