This document is a Justification and Approval (J&A) for a sole-source procurement by the Rock Island Arsenal - Joint Manufacturing and Technology Center (RIA-JMTC) for a Robotic Sand Milling (RSM-22) Cell from Tinker Omega Sinto LLC. The $864,461 contract (W519TC25P2231) will modernize the Army's foundry production capabilities by replacing traditional pattern box molding with an advanced sand routing technology that offers significantly improved manufacturing flexibility and efficiency.

The RSM-22 Robotic Sand Milling Cell provides key advantages over existing methods, including faster mold production (approximately five times faster for large molds), greater design flexibility, ability to easily customize and modify molds, and fully automatic machining with computer-aided design and manufacturing capabilities. The cell can produce pattern-less castings using a 6-axis milling machine that routes mold cavities from cured sand blocks, enabling more versatile and rapid part production for critical military equipment like war fighter components. The sole-source justification is based on Tinker Omega Sinto being the exclusive developer and distributor of this specific technology.
