What equipment is used to make pigtails

Producing pigtails requires specialized machinery tailored to the type of pigtail, including fiber optic production lines, coil spring forming machines, and rebar or industrial pigtail machines.

Fiber Optic Pigtail Production

For fiber optic pigtails, which are short fiber cables with one end terminated for splicing, a complete production line includes several key machines and tools: Cable Preparation: Automatic cable cutting machines and precise jacket strippers ensure accurate fiber lengths and clean exposure. Assembly & Crimping: Pneumatic or high-pressure crimping machines secure the Kevlar strength members to the connector body. Epoxy Injection & Curing: Automated epoxy injection systems and curing ovens solidify the ferrule bond.

Polishing: Fiber polishing machines with specialized jigs for SC, LC, FC, or ST connectors achieve the required UPC or APC geometry. Testing & Inspection: Video fiber microscopes for end-face inspection and IL/RL test sets verify insertion loss and return loss. These machines are designed for high-volume production, capable of producing hundreds of pigtails per hour, and ensure compliance with industry standards like Telcordia GR-326-CORE.

Mechanical or Coil Pigtail Production

For coil springs or rebar pigtails, specialized forming machines are used: Coil Spring Pigtail Machines: Automatically form the end of a coil spring into a pigtail shape using a forming jig controlled by a pre-set program. The jig can be adjusted for different pigtail shapes, and the machine can integrate with coiling and quenching processes. Rebar Pigtail Machines: Fully automated machines twist steel reinforcing bars into pigtail loops, using PLCs and sensors to detect bar size and apply precise torque.

Semi-automatic and manual versions exist for smaller-scale operations. These machines can produce 300–500 pigtails per hour depending on the model and material.

Accessories and Supporting Tools

Dies, Lubricants, and Tooling Kits: Enhance machine performance and longevity. Conveyor Systems: Facilitate high-volume production and integration with upstream and downstream processes. Inspection Tools: Ensure quality and consistency, such as torque meters for rebar or microscopes for fiber optics.

Summary

The choice of equipment depends on the type of pigtail and production scale. Fiber optic pigtails require a precision production line with cutting, crimping, polishing, and testing stations, while mechanical pigtails for springs or rebar rely on forming machines with programmable jigs and automation for high efficiency. Both setups benefit from supporting tools and quality control systems to ensure consistent, reliable output.
