Flawless Shell Insertion with Active Twisting:The built-in mechanical twisting spindle tightly winds the stripped wire core (adjustable from 1.5 to 12 mm) before the press strikes. This completely eliminates splayed copper strands, ensuring the crimped terminal fits effortlessly into its plastic housing cavities.
Unmatched Versatility Across AWG 28 to AWG 12:Handles an exceptionally wide range of wire sizes on a single machine. Seamlessly transition from delicate low-voltage signal lines to thick, heavy-gauge power wires with absolute consistency.
Blazing Fast Single-Head Output: Engineered for high-volume manufacturing, this workstation delivers a high throughput of up to 1500 completed pieces per hour at 300 mm lengths, keeping your assembly lines running at peak productivity.
Universal Tooling Compatibility:The heavy-duty press bolster accepts standard 30 mm and 40 mm stroke mini-applicators. This allows your team to utilize existing crimping dies from major connector brands like JST, Molex, and TE Connectivity without investing in custom tooling.
Saves Materials with Linear Precision:Driven by an intelligent control system, the machine maintains a tight cutting tolerance of ±(0.5+0.002*L)mm. This eliminates unnecessary margin allowances and significantly reduces wire scrap costs.
● Consumer Appliance Harnesses:Mass-produces single-ended pig-tail jumpers used inside refrigerators, microwave ovens, and heating systems where cables feed into multi-pin plastic housings.
● Industrial Controller Cabinet Wiring:Prepares flexible control wires with neatly twisted ends for clean, tool-free connection into push-in spring terminal blocks.
● Automotive Secondary Circuits:Delivers highly stable terminations for dashboards, lighting, and auxiliary sensor looms requiring high-spec open-barrel connections.
Q: Why is a single-head twisting and crimping machine preferred over standard crimpers for plastic housing terminals?
A: When standard machines strip a wire, the copper strands naturally untwist and spread outward. In typical applications, this might pass, but for terminals destined for plastic connector housings, even a single stray copper strand will catch on the plastic walls. This prevents the terminal from locking into position, leading to pushed-out pins. The EW-21D twisting module solves this by binding the strands tightly together prior to crimping, guaranteeing that every single wire filament is securely enclosed within the terminal collar.
Q: How does the EW-21D handle the transition from thick AWG 12 power cables to delicate AWG 28 signal wires?
A: The machine is engineered with adaptability in mind. The physical feed tension and stripping blade depths are fully adjustable via the intuitive bilingual touchscreen interface. The 2.0T mechanical press provides the necessary crushing force for heavy AWG 12 terminals, while remaining sensitive enough to execute clean, damage-free crimps on fragile AWG 28 wires when equipped with the appropriate applicator.
Q: What integrated safety features are in place to prevent production batch errors?
A: The EW-21D features a built-in sensor array that continuously monitors three critical parameters: wire presence, terminal feed status, and operational air pressure. If the wire run-out sensor detects the end of a reel, or if air pressure drops below the required threshold, the machine pauses instantly to prevent partial or low-force crimps. Additionally, an optional Crimp Force Monitor (CFM) can be integrated to analyze the exact pressure curve of every strike, automatically flagging out-of-tolerance crimps.
