Double-End Wire Seal Insertion and Terminal Crimping Machine, AWG 28–16 WM-377

Name: Double-End Wire Seal Insertion and Terminal Crimping Machine, AWG 28–16 WM-377
Brand: Wiromac
SKU: WM-377

CE Certified HS Code 8463.90 AWG 28–16 3,000 pcs/h

The WM-377 builds waterproof leads in one automated cycle — it cuts wire to length, strips both ends, slides a rubber wire seal onto each end and crimps terminals over both, at up to 3,000 pieces per hour for lengths within 100 mm. It covers AWG 28–16 wire and cutting lengths from 50 to 9,999 mm, holding tolerance within 1 mm plus 0.2% of length. Detection for missing wire, missing terminal, missing seal and low air pressure runs on every cycle, so bad parts stop at the station instead of reaching your customer.

Key features

Seals and crimps both ends in one pass — waterproof leads leave the machine finished, with no separate seal-threading bench
3,000 pieces per hour on leads within 100 mm keeps pace with automotive-volume delivery schedules
Four in-line checks — missing wire, missing terminal, missing seal and low air pressure — stop faulty parts at the station
2.0 and 3.0 ton crimping stations cover terminals across the full AWG 28–16 range, from signal wire to power leads

What it processes

Automotive and motorcycle waterproof connector harnesses with rubber single-wire seals
Sensor and lighting pigtails for engine-bay, chassis and outdoor equipment wiring
Harness plants replacing manual seal threading ahead of bench crimping presses

Suited for: waterproof automotive-style leads in AWG 28–16 where each end takes a rubber wire seal under the crimp — engine-bay, chassis, sensor and outdoor-equipment harnesses built at volume. If only one end needs finishing, or the station has to be switched between crimping and seal insertion depending on the order, the WM-3228 single-end crimping or seal inserting machine runs the same wire range on one terminal station at 348 kg instead of 440 kg.

Not suited for: unsealed leads — a plain double-end crimper like the WM-382 servo dual-end crimping machine runs those cheaper across AWG 14–28 — or housing insertion and wire outside AWG 28–16; browse the terminal crimping machines category for those jobs. Small batches that do not justify a full automatic line belong on the WM-3222 semi-automatic strip, seal and crimp machine instead — one station, pre-cut wire fed by hand, φ1.0–4.0 mm wire at 1,200–1,500 pieces per hour and 250 kg on castors.

Seal and terminal tooling is matched to your parts, so acceptance happens on your parts: send 2–3 meters of your wire with your terminal reel and seals, and we run the full cut, strip, seal and crimp cycle on this machine on video before you commit.

WM-377 — common questions

How does the machine handle the rubber wire seals?

Automatic feeders singulate the seals and thread one onto each stripped end before the terminal is crimped over it, and a seal-presence check runs on every cycle. Seal tooling is matched to your exact seal dimensions, so include seal samples with your inquiry for a confirmed setup.

What throughput should I plan for?

The rated 3,000 pieces per hour applies to cutting lengths within 100 mm — longer leads take longer to feed, so calculate capacity from your real lead lengths. Length tolerance holds within 1 mm plus 0.2% of cutting length across the whole 50–9,999 mm range.

What is the WM-377 not the right machine for?

Leads without seals are cheaper to run on a plain double-end crimper, and this model does not insert terminals into connector housings or process wire outside AWG 28–16 — see the other terminal crimping machines for those jobs.
