Their comprehensive finishing capabilities serve diverse industries where precision, consistency, and reliability are essential for component performance and longevity in demanding applications. The company's core service portfolio encompasses five primary metal finishing processes that address various customer requirements. Black oxide finishing provides enhanced corrosion resistance and improved appearance for steel components used in automotive, firearms, and industrial applications. Passivation services restore the corrosion-resistant properties of stainless steel components by removing free iron and other contaminants. Phosphating treatments create conversion coatings that improve paint adhesion and provide additional corrosion protection. Dip spin coatings offer uniform coverage for complex geometries, while their vision camera sorting capabilities ensure quality control and component verification throughout the finishing process. SWD Inc. maintains licensed applicator status for premium coating systems from industry-leading manufacturers including Doerken, Magni, and Yuken. This certification enables them to offer numerous automotive and industrial specifications that meet stringent OEM requirements and industry standards. Their licensed status demonstrates their commitment to technical excellence and ensures customers receive coatings that comply with manufacturer specifications and performance criteria. The company's expertise in applying these specialized coating systems positions them as a trusted partner for manufacturers requiring certified finishing processes. The company's fully automated coating lines represent a significant competitive advantage in the metal finishing industry. These advanced systems provide "Gentle Handling" capabilities that protect customer-supplied parts from damage during processing.
