Component Specifications

Definition
A mandrel shaft is a critical cylindrical tooling component in industrial press systems, specifically designed for stacking mandrel applications. It provides precise alignment, support, and forming surfaces during material processing operations such as coiling, winding, or pressing of sheet materials, tubes, or composite structures. The shaft maintains dimensional stability under high radial and axial loads while ensuring consistent product geometry.
Working Principle
The mandrel shaft operates by providing a rigid cylindrical form around which materials are wound, stacked, or pressed. During operation, it maintains precise alignment through bearing surfaces while withstanding torsional and compressive forces from the press mechanism. The shaft's dimensional accuracy ensures uniform material distribution and prevents deformation during high-pressure forming processes.
Materials
High-strength alloy steel (AISI 4140/4340), hardened to 45-50 HRC with surface treatments (chrome plating or nitriding) for wear resistance. Alternative materials include tool steel (D2, H13) for high-temperature applications or carbide-tipped designs for abrasive materials.
Technical Parameters
  • Length Range 500-3000 mm
  • Straightness 0.01 mm/m
  • Load Capacity Up to 50 kN radial, 100 kN axial
  • Surface Finish Ra 0.4 μm
  • Diameter Tolerance ±0.005 mm
  • Operating Temperature -20°C to 200°C
Standards
ISO 286-2, DIN 7150, ISO 2768-mK
