Water quality is one of the most important factors in industrial process. While this is carefully considered in cooling tower and finishing processes—it is almost always overlooked or totally neglected where metal-stamping processes are concerned. While many production facilities will obsess over the quality of diluent water for cleaning and surface treatment processes—especially rinsing stages—the same facility will use questionable city, well or river/reservoir supplied water for stamping processes.
Even though stamping lubricants are fortified to protect against tool wear, friction and corrosion—the same chemistry can behave very differently in differing water sources. The following series of bulletins will discuss the various effects poor water quality can have on stamping lubricants and why closer consideration should be given to diluent water.
