Semi-Automatic Ring and Fork Terminal Crimping Machine for 0.3–6 mm² Pre-Insulated Terminals WM-3220

›

The WM-3220 strips a pre-cut lead and presses a loose pre-insulated fork (U-type) or ring (O-type) terminal onto it in one cycle, covering 0.3 to 6 mm² wire at 600 finished pieces an hour. Terminals are tipped loose into a vibratory bowl instead of being threaded off a reel, two imported tungsten-steel rotary blades do the stripping, and the crimp is formed four-sided or double-sided up to a maximum crimp length of 12 mm. It runs on single-phase AC 220 V at 400 W, weighs 70 kg and takes up 540 × 570 mm of bench.

Specifications

Key features

• Loose ring and fork terminals feed from a vibratory bowl — nothing is threaded off a reel and no applicator strip is loaded, so a terminal change is a bowl refill and a feed-track setting
• Strip and crimp in one cycle: two imported tungsten-steel rotary blades take the insulation off and the press closes on the terminal, so the operator only presents the lead and takes it away
• Eight wire sizes are preset on the touchscreen — 0.3, 0.5, 0.75, 1.0, 1.5, 2.5, 4.0 and 6.0 — so moving between sizes is a key press rather than a tooling change
• Motor and imported ball screw drive the press, and the wire clamp is motor-driven with clamping force held by the control program rather than by shop air pressure
• Terminal shortage detection stops the cycle when the feed track empties, so no lead leaves the machine with a bare crimp
• 70 kg on a 540 × 570 mm footprint — a bench machine that sits beside the operator, not a floor cell that needs its own bay
• Free sample test — send your wire and a bag of your terminals, we run them on this machine and send you the video and the crimped samples before you order

What it processes

• Control panels, switchgear and distribution boxes, where insulated fork and ring lugs land on screw terminal blocks
• Appliance, motor and transformer lead sets in 0.3 to 6 mm² flexible wire
• Battery, inverter and combiner-box leads that bolt down through an insulated ring terminal
• Job shops that buy pre-insulated terminals loose in bags and currently crimp them with hand tools or a foot press

Suited for: pre-cut leads from 0.3 to 6 mm² that need a loose pre-insulated fork or ring terminal — the insulated spade and eyelet lugs that go onto screw terminal blocks, bolted studs and busbars. The wire is stripped and the terminal is pressed in the same cycle, and the terminals go in loose, the way they arrive from the supplier.

Not suited for: bootlace and tube ferrules — a ferrule is a different tool and a different feed. For those, the WM-397 E-tube terminal crimping machine does strip, twist and crimp in 2.5 seconds across 0.3–4 mm² and 2.5–6 mm², and the WM-3116 servo bootlace ferrule crimping machine runs 0.3–16 mm². Terminals that come on a reel belong on an applicator press — the WM-3102T 2-ton low-noise terminal crimping machine takes OTP and 2000# applicators. Conductors heavier than 6 mm² and bare copper cable lugs need tonnage this machine does not have; the WM-3135T 35-ton servo cable lug crimping machine presses terminals up to 120 mm².

If the volume outgrows an operator. This is a hand-paced bench machine at 600 pieces an hour and 70 kg. The WM-3212 fully automatic double-end pre-insulated terminal crimping machine feeds loose pre-insulated terminals from a bowl in the same way but pulls the wire off a reel, cuts it, strips both ends, twists the strands and crimps both ends unattended — AWG 24 to AWG 10, about 900 leads an hour, 550 kg. The trade is footprint and price against the operator you no longer need standing at the machine.
