Semi-Automatic Wire Rubber Seal Insertion Machine for Large Seals up to 13 × 14 mm WM-3231

›

The WM-3231 fits waterproof rubber seals onto wire ends and does nothing else. What sets it apart from a small-seal station is capacity: it takes seals up to 13 × 14 mm outer diameter by length — the largest seal envelope on this site — and runs at 60 cycles per minute. The whole machine weighs about 36 kg and occupies 200 × 600 × 630 mm, so it sits on a bench next to the crimping presses you already own. Seals are fed and oriented by a rotating perforated drum; the operator only presents the wire.

Specifications

Key features

• Takes large seals — up to 13 × 14 mm outer diameter by length, the widest seal envelope of any machine on this site, for heavy-gauge sealed leads that small-bore stations cannot swallow
• 60 cycles per minute of machine time, faster per cycle than a small-seal drum station
• About 36 kg and 200 × 600 × 630 mm — genuinely a benchtop machine, movable by one person, not a floor-standing cell
• Seal insertion only, so it drops in beside your existing crimping presses instead of replacing them
• Rotating perforated drum feeds and orients bulk seals; the drum face is open to view so the operator can see the seal level and top it up
• Screen sets drum and vibration on or off, drive voltage and frequency, continuous or single-shot running, with a live piece counter
• Free sample test — send your wire and your seals, we run them on this machine and send you the video plus the sample leads before you order

What it processes

• Heavy-gauge automotive and industrial sealed leads where the rubber seal is too large for a small-bore insertion station
• Harness shops that already crimp in-house and only need the seal step mechanised
• Energy-storage, EV and appliance harnesses built on thick single-core wire with large single-wire seals
• Low-volume and prototype sealed leads where a floor-standing seal-and-crimp cell cannot be justified

Suited for: mechanising the seal step on its own, for large single-wire rubber seals up to 13 × 14 mm, in a shop that already crimps. At about 36 kg and 200 × 600 × 630 mm it is a bench machine, and it needs 0.5–0.6 MPa of shop air.

If your seals are smaller and you need published bore, wire-diameter and accuracy figures to qualify the machine, the WM-3221 semi-automatic wire seal insertion machine is the better-documented choice at that end — seals up to 9 × 10 mm with a 0.6–3.0 mm bore, wire of 1–3.5 mm outer diameter, ±0.3 mm insertion accuracy, 50 insertions per minute.

Not suited for: anything past the seal itself. It does not strip, and it does not crimp.

• Seal fitted and terminal crimped in one cycle, two wires at a time — WM-3140FS double wire seal insertion and crimping machine, 0.2–2.5 mm² wire, seals φ ≤ 10 × 10, 3 T press, 1,000–1,200 pcs/h.
• Strip, seal and crimp at one bench position — WM-3222 semi-automatic wire stripping, seal insertion and crimping machine, φ1.0–4.0 mm wire, 2 T press, 1,200–1,500 pcs/h.
• Cut, strip, seal and crimp both ends unattended — WM-377 double-end wire seal insertion and terminal crimping machine, AWG 28–16, 3,000 pcs/h.
• Seals on some leads and plain crimps on others, from one automatic machine — WM-3228 automatic single-end terminal crimping or rubber seal inserting machine, AWG 28–16, 3,000 pcs/h, either operation selected per job.

The published data sheet for this machine gives the seal envelope, air, power, speed, weight and footprint, but no seal bore range, no wire diameter range and no stated insertion accuracy. We have left those blank rather than guess. Send wire and seal samples with your inquiry and we will measure all three on the actual machine and send you the figures and the video before you order.
