Double‑Arm Sleeving Winding Unit

GWD‑S16 Series Double‑Arm Sleeving Winding Unit

Single‑Wire & Multi‑Wire Options

Product Overview

The GWD‑S16 series double‑arm sleeving winding unit is high‑performance automated winding equipment independently engineered by Grewin Industrial Group (founded in 1993).

This bobbin winding winder includes two core variants: GWD‑S16 Double Arms Single Wire Single Sleeve Machine and GWD‑S16 Double Arms Three Wires Three Sleeves Machine.

 

Designed for mass‑volume SMPS, power supply, and high‑frequency transformer workshops across India and South Asia, this automated winding unit completes bobbin winding, sleeving, and terminal wrapping in one full production cycle. With a dual mechanical‑arm structure and 12 servo motors, the winding machinery delivers stable output, simplifies operator programming, and lowers coil defect rates for multi‑shift factory environments.

 

Manufacturers producing standard transformers and complex wound components can pick either single‑wire single‑sleeve or three‑wire three‑sleeve configuration according to their production bill‑of‑materials. The unit supports inline connection, allowing multiple winders to link up and build a fully automatic transformer production line.

Key Application Scenarios

SMPS high‑frequency transformer bobbin winding

Power supply coil & inductor component fabrication

Multi‑wire insulated bobbin coil manufacturing

Batch‑mode transformer production for electronic factories in India

 

Core Features

One‑cycle complete transformer winding: Simplified programming workflow, zero‑adjustment sleeving function plus automatic positioning. Operators finish full coil forming without repeated manual fine‑tuning.

Flexible inline production capability: Stand‑alone winding or multi‑unit connection to construct continuous manufacturing lines, adaptable for small‑batch trial and mass‑volume output.

Free terminal pin assignment: Start and finish terminals can wrap onto arbitrary bobbin pins (note: dual wires inside one sleeve cannot be separated).

Broad component compatibility: Works with most standard‑size transformer bobbins and handles complicated winding processes.

Versatile wire‑feeding mechanism: Shared feeding structure supports both fine magnet wire and relatively thick copper wire, enabling simultaneous thick‑thin wire production on the same winding equipment.

High‑density servo‑driven architecture: 12 servo motors guarantee precise movement for dual‑arm actions, improving winding consistency for high‑quality finished coils.

Important note for shop‑floor use: Each winding run handles one designated wire diameter (single‑wire variant) or matched multi‑wire sets (three‑wire variant). Do not mix unmatched wire gauges in one production batch.

Why Select Grewin GWD‑S16 Bobbin Winder for Your Indian Factory

Proven dual‑arm mechanical design reduces manual intervention, well‑suited for multi‑shift workshop running conditions.

Dedicated Grewin control system shortens the operator learning curve; less maintenance downtime compared with generic winding machinery.

Stand‑alone or line‑integratable layout: you can expand production capacity by adding more winding units later.

Grewin has supplied winding‑related equipment for transformer and inductor manufacturers across India for years, providing technical consultation and spare‑part support.
