Masking/Plugging

Back to All Finishes

Masking and plugging are precision preparation techniques used during the metal finishing process to protect specific areas of a component from receiving a coating, plating, anodizing treatment, or chemical conversion finish. By strategically covering selected surfaces, threads, holes, sealing areas, or critical dimensions, masking and plugging ensure that finishes are applied only where required while preserving the functionality and tolerances of protected areas. These techniques are essential for components with complex geometries or specialized performance requirements.

At Kion Tech, masking and plugging solutions are customized to each component's design and specification requirements. Using a variety of tapes, caps, plugs, fixtures, and specialized masking materials, our team carefully protects critical features throughout the finishing process. This attention to detail helps ensure dimensional accuracy, proper assembly fit, electrical conductivity where required, and compliance with customer and industry specifications across aerospace, defense, semiconductor, medical, and commercial applications.
