JH12-3J Fully Automatic Single-End Crimping & Insertion Machine – Free Length Tail, Twisting, Tinning

Product Overview

The JH12-3J is a fully automatic single-end crimping and insertion machine designed for wires requiring variable free lengths, middle twisting, and switchable tinning or semi-strip processing. It integrates automatic stripping, twisting, tinning, semi-strip switching, and terminal crimping with housing insertion in one continuous cycle.

The machine's defining feature is its ability to process wires with freely adjustable tail lengths – the exposed conductor length on the tinning or insertion end can be set independently, accommodating different connection distances between modules in home appliances, digital devices, and industrial equipment.

The JH12-3J also features middle twisting, allowing two or more wires to be twisted together at a specified midpoint – ideal for applications requiring paired or grouped conductors within a harness.

As part of JUHAI's comprehensive wire processing equipment lineup, the JH12-3J delivers efficient wire harness automation for manufacturers producing PCB connection wires, sensor cables, and multi-module internal wiring.

四、Key Highlights

• Free length tail – A-end wire length independently adjustable for different connection distances

• Middle twisting – Twists two or more wires together at a specified midpoint

• Tinning / Semi-strip switchable – Switch between full tinning and partial stripping

• Single-end crimping + insertion – Crimps terminal and inserts into housing on one end

• Automatic stripping, twisting, tinning – All processes integrated in one cycle

• Flexible wire configuration – Supports wires with different lengths in the same harness

• Precision processing – Suitable for fine-gauge electronic wires

• Applications – Home appliance control boards, digital device internal wiring, sensor cables, multi-module connections

六、Key Features

1. Free Length Tail – Variable Exposed Conductor Length

The JH12-3J allows the exposed conductor length on the processing end to be freely adjusted. This is essential for applications where wires connect to different points at varying distances – such as control boards with components at different locations.

2. Middle Twisting Function

The machine features a middle twisting function that twists two or more wires together at a specified midpoint. This is valuable for applications requiring:

• Paired conductors for signal transmission

• Grouped wires for organized harness routing

• Twisted pairs for noise reduction

3. Tinning / Semi-Strip Switchable

The JH12-3J offers switchable processing modes: full tinning for soldered connections, or semi-strip for applications requiring partial insulation removal.

4. Single-End Crimping + Insertion

The machine crimps a terminal onto one end and inserts it into a housing – completing the termination in one automated cycle.

5. Integrated Processing

Stripping, twisting, tinning, and crimping are all completed in one continuous cycle. This integration reduces handling, minimizes work-in-progress, and ensures consistent quality.

6. Precision for Fine Wire

The JH12-3J is designed for precision processing of fine-gauge electronic wires, with controlled stripping and twisting to prevent conductor damage.
