In short: Precision crimping joins wire to terminal with a controlled force and no insulation inside the conductor crimp, then automatic bundling gathers the crimped wires into a harness along a designed path. A servo press such as the LP-MC2024 paired with CCD vision verifies crimp height and wire presence on every piece, catching shallow crimps, jacket bite, broken strands and deformed terminals in cycle.

How automated crimping and bundling turn loose wires into tidy, reliable harnesses — and the equipment that makes the difference on a real production line.

What the Process Does
Precision crimping plus automatic bundling means crimping wires to terminals accurately, then gathering those crimped wires into a neat harness by a designed path. As electronics, cars, and appliances get more complex, the demand for reliable joins and orderly harnesses keeps rising.
Hand crimping and tying is slow and uneven — loose joints and tangled harnesses show up fast at volume. Automation fixes both: in a car, for instance, a messy or weak harness can mean bad contacts and unstable signals, so getting this right matters for performance and safety.
Crimping Equipment
The crimp itself forces the terminal onto the conductor for a sound electrical and mechanical bond, with no insulation in the conductor crimp. Whether fed by hand or automatically, the terminal is placed in the die, the stripped wire is inserted, and the upper die comes down.
- A servo-driven precision terminator such as the Lanneas LP-MC2024, paired with a CCD vision system, can check crimp height and wire presence on every piece. Monitored servo presses hold a programmable force window and flag shallow crimps, jacket bite, broken or lifted strands, and deformed terminals in real time.
- A double-end stripping-and-crimping machine with a servo CNC can cut to length, strip one or both ends, fit seals, crimp, and twist. With optional force monitoring it compares the force curve live against the approved reference.
- Linked to MES, the line logs and exports per-cycle data for audit and first-article inspection.
Bundling Equipment
The bundler is the part that shapes the harness. It gathers crimped wires by the drawing's route and branches, using tape wrap, cable ties, or corrugated or braided sleeve, into one tidy bundle that's easier to fit, service, and pack, and that takes less space.
- Tie method & spacing: tape comes in 6, 12, or 19 mm widths; ties are auto-fed, pulled, and cut. Tape spacing is adjustable (commonly 10–50 mm) or set at fixed points per the drawing.
- Bundle diameter: ranges from a few millimeters to over a hundred.
- Routing: wires are laid in a fixture or on a pin board with routing slots, then the head moves along to wrap or tie. Complex harnesses use a dedicated assembly board with locating pins and channels.
Why Shops Adopt It
- Speed: a full-auto line runs many times the hand rate for hundreds of harnesses per hour.
- Quality: sensors and controls hold length, strip, and crimp consistent, cutting rework. In-line inspection (e.g. J30J-WSM wire-sequence and pin-retention checks) catches defects manual QC misses.
- Cost: the upfront machine is pricey, but lower labor, less scrap, and higher throughput pay it back, with modest upkeep. Flexible programming and modules also handle varied specs without re-tooling.
Where It's Going
Next comes smarter gear that predicts and self-fixes faults from production data, more integrated and compact cells, greener materials and drives, and tighter links to MES and ERP for real-time, flexible production.
