Double-End Crimping and Heat Shrink Tube Inserting Machine with Laser Marking, 0.3–5 mm² WM-389

Name: Double-End Crimping and Heat Shrink Tube Inserting Machine with Laser Marking, 0.3–5 mm² WM-389
Brand: Wiromac
SKU: WM-389

CE Certified HS Code 8463.90 0.3–5 mm² 1,100–1,300 pcs/h

The WM-389 combines processes that usually occupy three benches — it cuts wire, strips and crimps terminals on one or both ends, threads heat shrink tube over the joint, laser-marks the tube and shrinks it in place, all in one automated pass. It handles 0.3–5 mm² wire (AWG 24–10) at 1,100–1,300 pieces per hour, cutting from 50 to 9,999 mm in 0.1 mm steps. Crimping force spans 2.0–4.0 tons on general OTP applicators, and sensors verify wire, tube, terminal and air pressure on every cycle.

Key features

Crimp, thread, mark and shrink in one pass — insulated, traceable joints leave the machine finished instead of visiting three separate benches
Laser marks your circuit code onto the shrink tube before it shrinks, so every lead carries permanent identification without stick-on labels
2.0–4.0 ton crimping on general OTP applicators covers 0.3–5 mm² wire, from signal leads to power circuits
Tube, wire, terminal and air-pressure sensors stop incomplete assemblies at the station rather than at final inspection

What it processes

Appliance and power-tool leads with insulated, code-marked crimp joints in 0.3–5 mm²
Control-cabinet and energy-storage jumpers where every circuit needs a printed identifier
Harness plants merging crimping, sleeve threading and marking stations into one line

Suited for: leads whose crimp joints must ship insulated and identified — appliance, power-tool, control-cabinet and energy-storage wiring in 0.3–5 mm², with shrink tube threaded, laser-marked and shrunk over the crimp automatically. Not suited for: shrinking pre-cut tube on finished cable assemblies — for that, pick the WM-661B heat shrink heating station, the dedicated hot-air bench for made-up assemblies — or wire outside 0.3–5 mm².

Tube, terminal and marking programs are proven on your parts: send 2–3 meters of your wire with your terminals and shrink tube, and we run the full crimp, thread, mark and shrink cycle on this machine on video before you commit.

WM-389 — common questions

Why combine shrink tubing and laser marking with crimping?

Handling is the hidden cost — each extra bench means another queue, another operator and another chance to mix up circuits. Here the tube is threaded, laser-marked with your circuit code and shrunk over the fresh crimp in the same cycle, so leads come off finished and traceable at 1,100–1,300 pieces per hour.

Which wires and terminals does it accept?

Wire from 0.3 to 5 mm² (AWG 24–10) with stripping lengths of 1–15 mm, crimped at 2.0–4.0 tons using general OTP applicators. Single-end and double-end programs cover cutting lengths from 50 to 9,999 mm set in 0.1 mm steps.

What is the WM-389 not built for?

It shrinks tube that it threads itself — for shrinking pre-cut tube on assembled cables see the heat shrink processing machines category, and for plain crimping without tubes the other terminal crimping machines run leaner. Wire outside 0.3–5 mm² is out of range.
