The WM-3140FS strips two pre-cut wires side by side, slides a rubber seal onto each and crimps both terminals in a 3-second cycle — 2 pieces per cycle, 1,000–1,200 sealed wires per hour from one operator. It covers 0.2–2.5 mm² wire and seals up to φ 10 × 10, with a listed cutting error of ±0.02 mm; seal seating is verified separately on the sample. The press delivers 3 T through a switchable 30 / 40 mm stroke; the floor-standing frame measures 125 × 123 × 179 cm at 450 kg and runs on 0.5–0.7 MPa shop air.

Specifications

Key features

• Two wires per machine cycle — stripping, seal fitting and crimping run in parallel lanes with one operator
• Seal goes on before the crimp, so the rubber sits captive under the terminal barrel the way sealed connector systems are designed to be assembled
• The specified cutting error is ±0.02 mm; stripping repeatability and seal seating depth are checked separately using your wire, seal and terminal
• 3 T press with the stroke switchable between 30 and 40 mm to suit different applicator standards
• Touchscreen setting of stripping, insertion and crimping parameters at the machine

What it processes

• Automotive waterproof connector leads — engine bay, chassis and lighting harnesses built on wire seals
• Sensor and actuator pigtails of 0.2–2.5 mm² that must pass sealed-connector pull and leak requirements
• Any double-up batch job where one operator currently feeds a seal station and a crimping press separately

Suited for: double-wire production of sealed, waterproof terminations — 0.2–2.5 mm² wire with rubber seals up to φ 10 × 10, the construction behind automotive and outdoor-equipment connectors. Not suited for: everyday unsealed crimping (the WM-382 servo dual-end crimping machine runs plain AWG 14–28 leads with no seal station) or tubular ferrule work — for that, pick the WM-3116 bootlace ferrule crimping machine, which strips, twists and crimps 0.3–16 mm² tube terminals. For jobs outside the 0.2–2.5 mm² range, request a sample review rather than converting conductor area to outside diameter. For suitable inner conductors of sheathed cable, compare the single-lane WM-3222 semi-automatic strip, seal and crimp machine instead — it is sized in outside diameter (φ1.0–4.0 mm), takes sheathed cable down to a 22 mm stripping length and runs 1,200–1,500 pieces per hour from one station. If your presses and applicators are already in place and the only missing step is the seal, the WM-3221 semi-automatic wire seal insertion machine does seal fitting alone — seals up to 9 × 10 mm with a 0.6–3.0 mm bore on wire of 1–3.5 mm outer diameter, at up to 50 insertions per minute.

Send 2–3 meters of wire plus your seals and terminals — we program both lanes, run your combination on camera and return the video with sample leads before you order.

The 2 pcs / 3 s machine cycle and 1,000–1,200 pcs/h output are different references. Operator loading, unloading and inspection affect accepted hourly production.
