Xwind Technologies offers Round Expanding Adjustable mandrels / formers that will collapse for easy coil removal. In addition to our standard design, we can customize design and manufacture to suits your application/needs at no additional cost.
Our Expandable Mandrels come with many expansion ranges for great flexibility. Medium duty - for smaller coils & heavy-duty high torque - for large coils. Our high-quality industrial mandrels assure many years of production use. Custom configurations, mounting plates, leaf shapes, and various drive styles (single or both ends - manual or powered).
With boost of high-quality, accuracy and precision in our Transformer Winding Mandrels. The accuracy maintained in our Transformer Winding Mandrels, which do not exceed a variation, not more that ±1 mm/mtr across the diameter of the entire working length. Our unique mandrel product design not only eliminates coil damages, but also eliminates the polygonal effect on coils.
Features:
Heavy-duty structure: Engineered to withstand high-torque operations, ensuring stability and durability during rigorous winding cycles.
Smooth collapsing mechanism: The collapsing operation by operating a single nut facilitates effortless and rapid removal of wound coils, preventing damage and improving production efficiency.
Precision alignment: Tight tolerance of +- 1 mm/mtr, and eccentricity of 0.5 mm/m, guarantees accurate wire placement and consistent coil geometry, crucial for electrical performance.
Custom diameters available: All our collapsible formers can be manufactured to specific dimensions to accommodate a wide range of coil requirements. Ensure clients can use the formers on all their existing machines.
Top covering material: Formers come with different Covering Materials Like Parma wood and HDPE nylon strips, as per the client’s choice.
