Precision Surface Preparation and Cleaning Services

The contract requires precise multi-stage surface preparation of aluminum optical mandrels to ensure optimal adhesion and performance prior to plating. The process includes solvent cleaning to remove oils and contaminants, followed by an alkaline soak to further decontaminate the surface, and an etching step to create a microscopically roughened texture. Two applications of zincate are then performed to establish a stable, uniform zinc layer, and a strike coating is applied to serve as a foundational metallic layer for subsequent plating operations. This sequence is critical for maintaining the dimensional accuracy and optical quality of the mandrels used in space-based instrumentation. The solicitation is categorized as a subcontract under NAICS code 332813, issued by the NASA Shared Services Center on behalf of the National Aeronautics and Space Administration. The contract was posted on July 2, 2026, with a response deadline of July 7, 2026, at 8:00 PM Eastern Time. No set-aside designation is specified, and there is no detailed information provided regarding the place of performance or point of contact. Interested parties must submit proposals through the designated SAM.gov portal prior to the deadline to be considered for award.
