Explore our factory-direct, CE-certified machine series tailored for electric motors, automotive subassemblies, HVAC blowers, and precision industrial pumps.
Aligning advanced stator inserting and winding automation with the technological demands of the Košice Self-Governing Region (Košický samosprávny kraj) and the Hornád industrial corridor.
With the expansion of Slovakia's automotive belt toward Eastern Slovakia—most notably the new mega-scale Valaliky Industrial Park near Košice dedicated to next-generation electric vehicle assembly—the need for localized sub-tier motor assembly has intensified. Our automated coil inserting and wedge making machines provide precision hairpin and round-wire insertion into low-voltage auxiliary drive stators, EPS (Electric Power Steering) units, coolant circulation pumps, and thermal management compressors.
Rooted in a profound legacy of metallurgy, metallurgical engineering, and heavy machinery around the U. S. Steel Košice complex and Kechnec Industrial Zone, regional plants require high-durability electric drive repair, rewinding, and serial production. The Zunqi automated slot paper insertion and heavy-gauge stator winding systems accommodate high-silicon electrical steel laminations, ensuring high slot fill rates without micro-fissuring or dielectric breakdown under harsh thermal stresses.
Suppliers across Košice, Prešov, and Michalovce producing commercial aeration units, industrial chiller fans, and hydronic circulation equipment rely on consistent slot wedge isolation. Our servo-driven coil and wedge insertion equipment processes Class F and Class H insulation paper (Nomex, DMD, NMN), executing synchronized pushing cycles that eliminate insulation cuff tear-out and ensure airtight IP55/IP68 motor compliance for European export.
Navigating the transition toward Ecodesign IE4/IE5 efficiency ratings and harmonized European safety compliance for motor production lines.
European motor efficiency regulations demand higher copper fill factors in smaller core envelopes. Our coil insertion blades push up to 80-85% slot fullness safely, minimizing joule losses and harmonic vibration to qualify stators for strict IE3, IE4, and Super Premium IE5 classes.
Every machine shipped to the Slovak Republic features full conformity certification: dual emergency circuits, Pilz/Sick safety interlocks, optical light curtain fencing, and EN 60204-1 compliant low-voltage electrical panels configured for European 400V 50Hz grid specifications.
To integrate seamlessly with enterprise MES and SCADA systems throughout Košice's tech corridors, our PLC controls provide native OPC-UA, Profinet, and Ethernet/IP connectivity, enabling real-time telemetry on insertion force, cycle times, and preventive maintenance triggers.
High-mix, low-volume (HMLV) European manufacturing mandates rapid changeovers. Our inserting machines utilize modular tooling cassettes, enabling stator stack height and slot diameter changeovers in under 25 minutes, reducing costly machine downtime.

Over seventeen years of dedicated stator manufacturing innovation, onsite verified production facilities, and an uncompromised commitment to long-term reliability.
From our central facility in Qishi Town, Dongguan, we have supplied hundreds of automated coil winding, inserting, forming, and testing systems to motor workshops across 40+ countries, fully acclimated to European customer quality demands.
Every stator profile is unique. We fabricate custom inserting blades, push rods, and wedge guide teeth specifically matched to your physical lamination samples, validated through comprehensive pre-shipment trial runs documented by 4K video evidence.
We minimize your spare parts overhead by integrating standardized, globally supported industrial components into your machines, including Siemens, Schneider, Mitsubishi, or Delta PLCs, SMC pneumatics, and Yaskawa servo drives.
Beyond stand-alone coil inserters, Zunqi designs synchronized, matched-cycle cells: from insulation paper insertion and high-speed multi-head winding to inter-phase forming, dual-end lacing, rotor turning, and shaft hydraulic press fitting.
Clear, definitive technical answers addressing logistics, electrical specifications, certification, and on-site integration in the Slovak Republic.
Whether you are expanding automotive auxiliary motor capacity, establishing high-efficiency HVAC assembly cells, or automating specialized pump winding, Zunqi delivers precision engineering, CE-certified safety, and factory-direct cost advantages.
