Fully Automatic Double-End Terminal Crimping Machine with Optional Waterproof Seal Stations WM-390
The WM-390 cuts, strips and crimps terminals on both wire ends fully automatically, covering 0.3–6.0 mm² wire with 4-ton crimping units — a heavier class than typical double-end crimpers. Cutting lengths run from 60 to 10,000 mm at under 1‰ total length error, and optional seal stations fit a rubber waterproof seal on each end before the crimp. The controller supports production records for actual length, crimp height, crimp force and pass count; the measurement arrangement for each field is confirmed on the quote, and the MES-ready controller imports worksheet data and prints a process ticket per batch.

Key features
- Optional seal insertion stations fit a rubber waterproof seal before crimping — confirm one-end or two-end tooling on the quote; retrofit compatibility is assessed for the installed configuration
- 4-ton crimping units and a 0.3–6.0 mm² wire range take power leads that lighter AWG-class double-end crimpers cannot close
- Built-in encoder and crimp force monitoring with fault alarm — every cycle is measured, and tracking feed moves wire without indentation marks
- MES-ready control system imports worksheet data, accepts scheduling from your MES and supports remote upgrade; production records per piece cover actual length, crimp height, crimp force and qualified quantity
- Modular ball-screw and rotary-reducer construction supports servicing; the maintenance schedule and wear parts are confirmed for the supplied configuration
- Process ticket printer is standard; an optional inline inkjet changes printed characters on the fly within 50 mm of wire, and an optional two-layer take-up handles leads up to 10 m and discharges rejects automatically
What it processes
- Waterproof automotive, motorcycle and outdoor-equipment harnesses with single-wire seals under both crimps
- Power and control leads from 0.3 to 6.0 mm² double-end crimped at volume for appliances, cabinets and energy products
- Long jumper leads up to 10 meters using the optional two-layer take-up with automatic reject discharge
Suited for: double-end crimped leads in 0.3–6.0 mm² wire — including waterproof harnesses once the optional seal stations are fitted — and plants that need per-piece crimp force records for MES traceability. Not suited for: cable cross-sections above 6.0 mm² — battery and lug work belongs on the WM-3135T 35-ton cable lug crimping machine pressing terminals up to 120 mm² — or two pre-cut wires processed side by side for seal insertion and crimping, which is the job of the WM-3140FS double wire seal insertion and crimping machine covering 0.2–2.5 mm² pairs. For anything else in this class, browse the terminal crimping machines category.
Crimp and seal tooling is matched to your parts, so acceptance happens on your parts: send 2–3 meters of your wire together with your terminal reels (and seals, if you take the seal stations), and we run the full cycle on this machine on video before you order.

WM-390 — common questions
Are the waterproof seal stations included in the base machine?
The base WM-390 is a fully automatic double-end crimping machine; the seal insertion stations are optional working stations fitted for one or both ends. Seal tooling is matched to your exact seal dimensions, so send seal samples with your inquiry and we confirm the setup before quoting.
What production records does the machine keep?
The controller supports records for actual cut length, crimp height, crimp force and pass/fail results, with a standard process-ticket printer. Confirm how each field is measured or entered for the supplied configuration; crimp-force monitoring alone is not a direct crimp-height measurement. The controller can import worksheet data, take scheduling from an MES system and be upgraded remotely.
How accurate is the cut length on long leads?
Length is measured by a built-in encoder, holding total length error under 1‰ across the whole 60 mm to 10,000 mm range — under 10 mm on a 10-meter lead. For leads at the long end of the range, the optional two-layer take-up coils the finished wire and separates rejected pieces automatically.
