Session 2: Metal Finishing: Past, Present, and Future

Abstract Number:

For applicators that produce welded or laser cut components, the ‎necessity for a robust yet ‎sustainable scale removal process is ‎critical. Leaving oxide and scale on a component will diminish ‎the ‎final part quality; often the weld or laser cut areas of these ‎components have poor adhesion of ‎the finish and become the first ‎point of failure. This presentation will address how to overcome ‎‎these concerns with modern technologies.‎

Topics:

Advances in Surface Finishing Technology
Technologies for ‎Improved Performance or Increased Efficiency

Applicators that produce welded and/or laser cut components are often tasked with ‎identifying the ‎most ideal way to integrate scale removal into their production process. ‎Unaddressed, oxide and ‎scale can compromise the finished part quality greatly, whether ‎considering a painted or plated ‎component. Traditionally, mechanical methods like grinding ‎or media blasting have been used due ‎to their relatively low upfront equipment cost. Others ‎will utilize chemical methods, often ‎commodity acids, to manage their scale removal needs. ‎These processes work but come with several ‎disadvantages. This leaves applicators seeking ‎a safer and more sustainable solution.‎

The most economical method for integrating scale removal processes is directly into the ‎existing ‎finishing system. This is rather easy to accomplish for lines already utilizing ‎conventional chemical ‎scale removal chemistries, applicators with floor space to add ‎additional washer capacity, or for new ‎line builds. For others this has long been a challenge ‎and reason many have selected traditional ‎scale removal processes, but advancements in ‎proprietary chemistries are now allowing applicators ‎to integrate it into their existing ‎finishing process without major modifications. The result is a ‎simplified process that meets ‎applicator's needs without significant investment.‎

This presentation will explore deeper what conventional scale removal methods are, their ‎‎disadvantages, and how applicators can overcome them with a more sophisticated and ‎sustainable ‎approach to scale and oxide removal. Although most of the presentation and ‎case studies presented ‎will be focused on paint applications, the advancements in descaling ‎technology can also be applied ‎to plating applications as well.‎
