Detailed Description
Overview
This cylindrical adjustable winding mandrel is engineered for flexibility and efficiency. Its vertical and horizontal dual-use capability means you can mount it on different winding machines without changing tooling. The variable diameter mechanism enables quick size adjustment, making it ideal for prototype development and small-batch production.
Key Features
Dual orientation – Works in both vertical and horizontal winding positions
Variable diameter – Quickly adjust to different coil inner diameters
Rigid construction – Maintains accuracy under winding tension
Compatible design – Fits standard winding machine shafts
Benefits
One mandrel replaces multiple fixed-size mandrels
