Review confirmed:
The correct terminal crimping machine is determined first by the terminal system, then by output. Selecting on tonnage or pieces per hour before confirming terminal presentation and tooling is the fastest route to an unusable machine. Match feed, applicator and crimp profile to the actual terminal drawing, then verify crimp height, pull result and changeover on your samples.
Classify the termination before selecting equipment
| Termination | Typical tooling route | Key question |
|---|---|---|
| Reel-fed open-barrel terminal | Applicator in a bench press or automatic line | Which applicator standard and feed direction? |
| Loose bootlace ferrule | Bowl or loose-piece feeding system | Which ferrule lengths and conductor sizes? |
| Tubular cable lug | Guided die with hydraulic or servo force | Which lug drawing, material and crimp profile? |
| Pre-insulated ring or fork terminal | Matched die and controlled positioning | Does insulation support require a second geometry? |
| Seal plus terminal | Seal insertion before crimping | What seal, lubrication and insertion depth? |
The terminal drawing and reel strip are more useful than a photograph. Provide carrier pitch, material thickness, feed direction and crimp specification. If the applicator already exists, provide its interface and shut height.
Choose the production architecture
Bench or semi-automatic press
A bench press is suitable when operators present pre-stripped wire, product mix is high or existing applicators must be reused. The WM-3130T servo terminal crimping machine is a controlled press platform; the final tooling still has to be matched to the terminal.
When an operator presents a pre-cut fine wire but terminals feed from a reel, the WM-395 strip-and-crimp station combines end stripping with applicator crimping. Confirm the terminal feed direction and applicator interface; cutting wire to length remains a separate step.
For connector contacts needing matched feeding and crimp tooling, review the WM-3116B connector-contact configuration with the contact drawing and inspection criteria. Compatibility is established for the actual contact and tooling; the aviation-style description is not aerospace qualification.
Fully automatic cut-strip-crimp line
A line such as the WM-3202 automatic double-end crimping machine is intended for repeat production where wire cutting, stripping and terminal application can run as one sequence. Its practical output depends on wire length, terminal feeding, process options and inspection plan—not only the machine’s headline rate.
Integrated identification and ferrule processing
Control-panel production may benefit from combining identification, stripping and ferrule crimping. The WM-393 number-tube printing and ferrule crimping machine addresses that workflow. Compare this with the flexible bench-cell approach described in the control panel wiring application guide.
Compare servo, pneumatic and mechanical presses
Drive type is separate from applicator feeding. For example, TE’s bench-press documentation describes motor-driven presses accepting different applicator feed systems. An air-fed applicator does not make the press pneumatic.
| Press route | When we would trial it | Check before choosing |
|---|---|---|
| Servo drive | Jobs needing the quoted programmable motion or setup controls | Which parameters are adjustable, and whether monitoring and logging are included |
| Pneumatic drive | Operator-loaded terminals with matched dies and a suitable air supply | Required pressure during operation, full die closure and terminal positioning |
| Conventional mechanical linkage drive | Repeat jobs within the press’s stroke and applicator interface | Shut height, available stroke, adjustment method and tooling condition |
Ask how the proposed motor or cylinder moves the ram; specify the transmission and its controls separately. None of these labels guarantees a better crimp. If the tooling interface or loading clearance fails, select another terminal press or lug-crimping configuration before comparing drive types.
Run the same wire-terminal combination on each candidate. Check first-piece approval, a repeated run and the first piece after changeover using the criteria below. Compare press plus applicator cost, compressed air where needed, maintenance, setup time, inspection and rejects at the same annual workload. A servo premium needs a demonstrated process benefit; a lower-priced press still needs to pass the same acceptance checks.
Specify acceptance before ordering
Our sample trial begins with written criteria:
- crimp height and width where specified by the terminal supplier;
- conductor brush and bellmouth condition;
- no cut or missing strands;
- insulation support position;
- pull-force threshold for the exact wire and terminal combination;
- cross-section requirements for compression, symmetry and voids when applicable.
The WM-813 crimp cross-section analysis system supports destructive section analysis. Pull force, cross-section and visual inspection answer different questions; one should not be presented as a substitute for the others.
A practical selection checklist
- Identify terminal presentation and tooling interface.
- Define every process step before and after crimping.
- Group orders by terminal and wire family to estimate real changeover frequency.
- Decide whether the operator loads the wire or the machine cuts from a reel.
- Write acceptance criteria before the trial.
- Trial the actual wire, terminal, seal and applicator combination.
See the power-cord production sequence or EV harness process for complete line context. Approved evidence is published in the case library. To match a terminal and applicator, send the drawings and sample details.

Questions engineers ask
What determines whether a terminal can run on a crimping machine?
The terminal presentation, applicator interface, strip dimensions, wire range and required crimp geometry must all match. A terminal on a reel, loose ferrule and tubular cable lug require different feeding and tooling systems.
When is a fully automatic crimping line justified?
It is justified when part families repeat long enough to recover setup time and when cutting, stripping, seals or double-end operations can be combined reliably. High product mix and short orders often favor separate semi-automatic stations.
How should a crimp be approved before production?
Approval should use the terminal supplier's dimensional and pull-force criteria where available, plus visual inspection and crimp cross-section analysis when required. Record the wire, terminal, applicator and settings used for the sample.
