Press forming is a blending operation which is used to give shape to a sheet or to make it shallow. Sometimes people usually confuse press forming with blending; however both of them are different because latter one produces more complex and multi axis shapes. Before this process is used it is important for an individual to understand failures which one can come across due to cold mechanism and what implications it can leave behind.
The process may lead to wear and tear in materials used during the process. The loss is mainly of tooling material and it can be in terms of hardness, volume or the carbide type. However the amount of wear and tear suffered shall vary depending on the quality of sheet used and what were the process conditions when press forming was taking place. Some portion of the steel may chip away due to its inability to resist the process, it is hence important to pick up good quality steel which can pass through the process successfully. The steel may also have to suffer from plastic deformation but it happens specifically in cases where the process stresses a lot on the steel however steel does not has that much strength to bear it.
Once failures have been identified some of the basic decisions rest on individuals which includes identifying as to what kind of steel is prone to failure, selecting a steel which has the capability of overcoming such failure and lastly matching the choice of steel to your requirement and exposing it to the process.
