SMALL PARTS MANUFACTURING CO., INC.

Small Parts Manufacturing Co., Inc. specializes in the precision fabrication of aluminum sheet, plate, and foil components for defense applications, with demonstrated expertise in manufacturing custom enclosures that meet stringent military environmental and structural requirements. Their core capabilities include cold rolling, shearing, stamping, and forming of high-purity aluminum alloys to achieve tight tolerances and surface finishes suitable for electromagnetic shielding, thermal management, and ruggedized housing applications. The company’s technical focus centers on producing dimensionally stable, corrosion-resistant enclosures for sensitive electronic systems, leveraging material science knowledge of aluminum tempers and grain structures to optimize mechanical performance under vibration and thermal cycling. Their specialization lies in low-volume, high-precision manufacturing where geometric accuracy and material integrity are critical to mission success. The contractor has delivered directly to the Department of Defense, providing mission-critical aluminum enclosures for naval and defense systems. Their work supports integrated electronic subsystems requiring durable, lightweight housings that comply with military specification standards for environmental sealing and EMI/RFI attenuation. The relationship reflects a focused supplier partnership centered on niche, non-commodity components essential to defense hardware assembly. The primary NAICS 331315 reflects a niche manufacturing capability in engineered aluminum forms, positioning the company within the defense supply chain as a specialized producer of raw material-derived components rather than finished systems. This vertical specialization distinguishes them from broad-spectrum fabricators, targeting applications where material properties and dimensional consistency are paramount. Small Parts Manufacturing Co., Inc. is a small, locally based manufacturer headquartered in Portland, Oregon, operating as a 2L entity with no federal certifications on record. Their market presence is defined by direct, contract-specific engagements with defense customers, emphasizing technical precision over scale or broad certification compliance.
