3. 3 Core Technologies

Independent Servo for Every Spindle
This 6-axis dense winding machine adopts an independent servo drive structure for each spindle, abandoning the traditional single-shaft driving mode. Every spindle supports separate speed adjustment, wire tension control and stroke setting. It ensures high consistency during mass coil production and perfectly suits thin wire and multi-type coil manufacturing.
Encoder Closed-Loop Needle Control — Fully Digitized Winding Precision
Equipped with encoder real-time feedback system, this automatic dense winding machine precisely controls needle verticality and movement track. It eliminates manual adjustment errors and effectively avoids needle offset, uneven coil end faces and winding deviation. Stable precision is guaranteed for high-density dense coil winding.
Synchronized 6-Axis Dense Winding Process — Flat Coils and Low Defect Rate
The system synchronizes all six spindles with unified tension and operation beat. The dense winding process produces compact, flat and neat coils with stable space factor. It greatly reduces wire overlapping and edge collapse, meeting strict quality requirements for automotive relays, high-precision inductors and electromagnetic coils.

4. Multi-Product Flexible Production — Fast Model Switching

This 6-axis dense winding machine comes with 3 sets of standard bobbin fixtures. Product switching only requires fixture replacement and parameter recall, no complicated debugging. One dense winding machine supports multiple coil specifications, helping manufacturers save equipment investment and workshop space. It fully adapts to small-batch and multi-variety production modes.

5. Tandem Connection Design — Expandable Production Capacity

The automatic dense winding machine can work independently or be connected in series for capacity expansion. Tandem operation unifies production beats and improves overall line efficiency. It reserves long-term upgrade space and avoids repeated equipment investment for coil factories.

6. Standard Brand Configuration — Stable and Easy Maintenance

This dense winding machine adopts mainstream industrial components for stable performance and convenient after-sales maintenance:

Inovance PLC: open interface, one-click parameter storage and recall
Inovance Servo System: fast response and stable high-speed winding precision
Airtac Pneumatic Parts: durable, widely available spare parts

Universal standard accessories lower long-term maintenance costs and reduce equipment downtime.
