Automatic Sheathed Cable Machine for Single-End Crimping and Single-End Tinning WM-391
The WM-391 turns multi-core sheathed cable into finished leads in one enclosed cell — wire cutting, double-end jacket and core stripping, terminal crimping on side A and core twisting plus tinning on side B. It processes cable of 2.0 to 6.5 mm outer diameter, cutting 80 to 1,000 mm lengths (customizable), stripping the jacket 10 – 45 mm on the crimp side and 10 – 100 mm on the tinning side. Output runs 500 to 1,500 pcs/h depending on core count, with air-pressure detection and alarm guarding every cycle.

Key features
- Replaces four hand stations in one pass — cut, strip both ends, crimp side A, twist and tin side B, untouched in between
- One lead leaves with a crimped terminal for the connector and a tinned end for the solder joint, so both downstream processes get the finish they need
- Jacket strips reach 100 mm on the tinning side for long-reach terminations inside housings and junction boxes
- Air-pressure detection alarm halts the cycle when supply drops, protecting crimp height before bad parts pile up
What it processes
- Appliance and small-motor leads — connector-crimped on one end, PCB-tinned on the other
- Control panel and power-adapter cable assemblies from 2 to 10 core sheathed cable
- Harness shops consolidating cut-strip-crimp-tin lines for OD 2.0 – 6.5 mm cable into one cell
Suited for: multi-core sheathed cable from OD 2.0 to 6.5 mm (2–10 cores) that must leave the machine crimped on one end and twisted-plus-tinned on the other, at 500–1,500 pcs/h. Not suited for: loose discrete wires that need crimping and tinning at higher piece rates — for that, pick the WM-3201 automatic wire crimping and tinning machine, which runs AWG 14–28 single leads at 2,000–3,000 pcs/h with the same crimp-plus-tin finish. If your 2-core or 3-core cable needs a terminal crimped on every conductor rather than one crimped end and one tinned end, the WM-399 staggered core stripping and crimping machine strips each core to its own length and crimps all of them at 4 tons, 1,200–1,500 pcs/h.
Every cable construction behaves differently in the twist-and-tin stage, so we prove it first: send 2–3 meters of your actual cable and we run it on this machine on video before you commit — crimp side and tinned side both on camera.
The equipment table includes a 500 cycles/h reference and separate 500–1,500 pcs/h figures by cable construction. Confirm the counting basis and accepted lead output with the actual cable during the trial.

WM-391 — common questions
How fast does the WM-391 actually run on my cable?
It depends on core count. The specification lists OD within 5.0 mm (2 – 4 cores) at 1,500 pcs/h, 5.0 – 5.5 mm (5 – 7 cores) at 1,000 pcs/h, and 5.5 – 6.5 mm (7 – 10 cores) at 500 pcs/h. Send us your cable construction and we confirm the real cycle on video.
How long can each end be stripped?
On the crimping side (A) the jacket strips 10 – 45 mm, customizable, with core wires stripped 1 – 15 mm. On the tinning side (B) the jacket strips 10 – 100 mm with the same 1 – 15 mm core window — enough reach for leads that terminate deep inside an enclosure.
What can it not do?
It crimps one end only — it will not put terminals on both ends, and it is built for sheathed multi-core cable rather than loose single wires. For double-end crimping and other terminal work, start from our terminal crimping machine range.
