TREAS - Physical Vapor Deposition (PVD) Laser Cleaning - MRAS

The Department of the Treasury, through the General Services Administration (GSA), is conducting market research to procure ablative laser cleaning services for its IPC 1100 Physical Vapor Deposition (PVD) machines. These machines are located at the Bureau of Engraving and Printing's facilities in Washington, DC, and Fort Worth, TX. The PVD process is critical for producing high-quality thin coatings on surfaces by converting solid materials into vapor which then deposits onto a surface. This coating process is essential for the production of intaglio plates used in currency manufacturing.

The primary goal of this contract is to replace labor-intensive manual cleaning methods with a highly controlled, non-contact laser process. This will help reduce equipment downtime and prevent mechanical damage to sensitive vacuum surfaces within the PVD machines. The contractor will be responsible for providing all necessary labor and specialized equipment to perform ablative laser cleaning on four IPC 1100 PVD systems and their associated stainless steel components. The service must ensure complete removal of chrome build-up while maintaining the structural integrity of these components.

Technical requirements specify that the contractor must use an ablative laser system with a minimum power output of 100W to achieve uniform energy distribution during cleaning operations. This ensures consistent removal of chrome without creating hot spots that could damage substrates. Additionally, the process must be free from chemicals or abrasive media to avoid contaminating the PVD vacuum chamber with debris or residues.

To ensure safety during operations, contractors are required to integrate a high-capacity Laser-Generated Air Contaminant (LGAC) extraction unit with multi-stage filtration into their systems. Contractors must also comply with stringent occupational exposure limits for various contaminants such as chromium species and oxides of nitrogen. Personal protective equipment (PPE) will be mandatory for personnel operating within laser-controlled areas, ensuring compliance with site-specific safety plans and job safety analyses.
