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