How Fixed-Length Cable Seals Are Manufactured: From Steel Cable Cutting To Custom Printing

Fixed-length cable seals are widely used for tamper-evident security in logistics, transportation, warehousing, utilities, retail, and asset management. Their reliable locking structure and durable design make them an effective solution for protecting goods while providing clear visual evidence of unauthorized access.

This video takes you inside the Junyue Security Seal factory to demonstrate the complete manufacturing process of our fixed-length cable seals, highlighting the precision and quality control behind every product.

Step 1: Steel Cable Cutting

Production begins with cutting high-quality steel cable to the required length. Accurate cutting ensures dimensional consistency and reliable performance for every seal.

Step 2: End Plug Installation

A precision end plug is securely installed onto the cable. This component is essential for smooth insertion and dependable locking performance.

Step 3: Lock Body Assembly

The locking mechanism is assembled with strict dimensional control to ensure each seal locks securely and cannot be reopened without visible damage.

Step 4: Plastic Injection Overmolding

The assembled lock body is encapsulated using injection molding technology. The plastic housing protects the internal locking mechanism while providing a durable surface for customized printing.

Step 5: Custom Printing

To support product identification and supply chain traceability, we offer customized printing services including:

• Company logos

• Sequential serial numbers

• QR codes

• Barcodes

• Variable data

• Warning messages and custom text

Our advanced laser marking technology produces clear, permanent markings with excellent resistance to wear and handling.

Step 6: Quality Inspection

Before packaging, every production batch undergoes comprehensive quality inspection to verify locking performance, print quality, dimensional accuracy, and overall appearance. This ensures every cable seal meets our quality standards before shipment.
