Summary:The leakproofness of shock absorber tubes is one of the most important parameters determining the quality of these types of automotive parts. The technological parameters of forming their bottoms, as well as material properties strongly influence shock absorber leakproofness. This work focused on analysing the cause bottom cracking of shock absorber cylindrical tubes produced by the “hot bottom forming” method. The investigations showed that the cracks mainly resulted from improper parameters of the manufacturing technology. •Root cause analysis of cracks in the shock absorber tubes produced by hot bottom forming was made.•Formation of cracks resulted from improper parameters of manufacturing technology•Recommended technological improvements fixed problem
