Automatic Flat Ribbon Cable Double-End Terminal Crimping Machine, 3–20 Pins WM-3215

›

The WM-3215 terminates flat multi-conductor cable — ribbon, DuPont-style and similar 3-to-20-pin cable — in one automatic cycle: it cuts to length, splits the web between conductors, strips every tail and crimps a terminal onto each conductor at both ends. Rated at 15,000 terminals per hour, with 20–40 pins available as a customization, a servo linear screw transfer and Japan DC53 tooling.

Specifications

Key features

• Built for flat cable, not round wire — the cycle splits the insulation web between conductors before stripping, so a whole row of tails is prepared at once instead of one wire at a time
• Both ends terminated in the same pass; the machine also runs single-head crimping when only one end needs a terminal
• 3 to 20 pins as standard, 20 to 40 pins available as a customization, with split length set at 25 mm or more from the end
• Servo linear screw transfer moves the cable between stations; cylinder hold-downs clamp the flat cable flat so the conductors stay in register through the press
• Japan DC53 tool steel for the cutting and stripping tooling
• In-cycle detection covers wire presence, terminal presence, crimp pressure and wire breakage, so a fault stops the run instead of filling a bin with bad leads

What it processes

• Ribbon and DuPont-style cable assemblies for consumer electronics, instruments and appliances
• Flat multi-conductor jumpers between PCBs, backplanes and control boards
• Harness shops replacing hand splitting and bench-press crimping on flat cable, where every conductor in the row has to be terminated

Suited for: flat multi-conductor cable — ribbon, DuPont-style and similar 3-to-20-pin cable, 60 mm long and up — that has to be cut, split into separate conductors, stripped and crimped with a terminal on every conductor at one or both ends. Not suited for: single round discrete wire. That is a different feed and a different tooling set: for AWG 18–28 at 3,800 or more pieces per hour, use the WM-3202 automatic double-end crimping machine, and for AWG 30–14 with strip lengths to 35 mm and ±0.02% cut tolerance, the WM-3210 servo double-end crimping machine. If your terminals arrive loose in a bag with the insulation sleeve already on them, neither those nor this machine will feed them — the WM-3212 double-end pre-insulated terminal crimping machine orients loose pre-insulated terminals in a vibratory bowl and covers AWG 24–10 at 900 pieces per hour. For flat power cable in the 10–120 mm² class the WM-161PX flat cable cutting, slitting and stripping machine does the cut, slit and strip at 1,800 pieces per hour — note that it stops at stripping and does not crimp. And if the flat thing you are terminating is a printed flex circuit rather than a cable of separate conductors, that is the WM-385 membrane switch crimping machine, which crimps 2P–20P FPC and FFC tails at 2.0 T on a single end.

Where this sits against our round-wire double-end crimpers: the WM-3202 and the WM-3210 both start from a spool of single wire and produce one lead per cycle, and they are quoted in pieces per hour because every piece carries exactly two crimps. The WM-3215 starts from flat cable and produces a whole row of terminated conductors per cycle, which is why it is quoted in terminals per hour instead. The mechanism differs accordingly: this machine has to split the conductor web, hold the row of tails in register through a comb clamp, and index the press across the row. It is the larger machine of the group — 1,800 × 1,600 mm and 620 kg — because of that extra motion.

The other thing worth checking before you choose is the upstream step. If your flat cable only needs cutting, splitting and stripping and you crimp elsewhere, a smaller machine will do: the WM-182 2-pin flat cable cutting, stripping and splitting machine is a 33 kg benchtop unit for 2-pin flat cable at 1,000–2,000 pieces per hour, and the WM-1220 flat ribbon cable cutting and stripping machine covers 2 to 12 pins — cutting, splitting and stripping 0–15 mm at 3,000–5,000 pieces per hour, with middle stripping, but no crimping.

Flat cables differ in pitch, web thickness and conductor gauge more than any datasheet shows. Send us 2–3 metres of your actual cable and a strip of your terminals — we set the machine up, run your sample on camera, and you judge the split and the crimp before you commit to the order.
