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.
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

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.
| Industry | Typical Application | Why JH12-3J |
|---|---|---|
| Home Appliances | Control board harnesses with wires connecting to different points at varying distances | Free length tail accommodates different connection distances. Middle twisting organizes paired wires. |
| Digital Devices | Internal module connections requiring different wire lengths | Variable free length eliminates manual trimming. Tinning prepares wires for PCB soldering. |
| Industrial Control | Sensor cables and control wiring with twisted pairs | Middle twisting for noise reduction. Single-end insertion for plug-in connections. |
| Consumer Electronics | Power and signal wiring in compact devices | Precision processing for fine wires. Flexible length configuration. |
Q1: What is the main feature of the JH12-3J?
A: The JH12-3J features a free length tail (variable exposed conductor length), middle twisting, and switchable tinning/semi-strip processing.
Q2: What is middle twisting?
A: Middle twisting twists two or more wires together at a specified midpoint – useful for paired conductors, grouped wires, or twisted pairs for noise reduction.
Q3: Can the machine switch between tinning and semi-strip?
A: Yes. The JH12-3J supports switchable tinning and semi-strip modes.
Q4: What does "free length tail" mean?
A: The exposed conductor length on the processing end can be independently adjusted, accommodating different connection distances.
Q5: What wire types does the machine process?
A: Electronic wires for PCB connections, sensor cables, and internal device wiring.
