Brake Band
Benefit: Weight Saving
Main Forming Process: Conventional Processing
End Use Sector: Automotive
Material: Ferrous

Finishing: Deburring, Steam Treatment, Cracking

Requirements

These components are used in manual seat-height adjustment devices in automobiles. With a total of five other uniaxial compacted powder-metal components, a set of two brake bands are fitted into each adjustment unit. It is the narrow tolerances of this component which pose a big challenge for the process technology.

Benefits

With a thinnest wall thickness of less than 2mm, and an outside diameter of 53mm, high tolerance demands are also placed on the evenness of the component, amounting to 0.2mm with the total height of the part being 4mm. The use of PM being a carefully controlled and fully linked production process enabled the manufacture of several million such components in compliance with the tolerance demands.

Component Specification

Density (g/cm3): 6.85
Tensile Strength (MPa): 250
Hardness (HV10): 80
