Alloy steel and tool steel are optimal for mandrels due to their high strength, wear resistance, and durability under the stresses of coil winding in downcoilers.
The mandrel acts as a cylindrical shaft that expands via hydraulic actuators and segments to form and support the metal strip coil during winding, ensuring tight, uniform coils.
Essential BOM items include the mandrel body, expansion segments, hydraulic actuators, and drive connection, all critical for performance and requiring regular inspection.
