SIMPSON TECHNICAL SALES, INCORPORATED

SIMPSON TECHNICAL SALES, INCORPORATED specializes in precision metal casting for defense-grade applications, with core expertise in nonferrous die-casting and steel investment foundry processes. The company produces high-integrity components such as bronze aluminum parts and lever castings, adhering to strict military specifications for dimensional accuracy, material consistency, and structural integrity. Their technical proficiency lies in complex mold design, molten metal control, and post-casting finishing techniques required for mission-critical aerospace and ordnance systems. Differentiators include the ability to execute low-volume, high-precision runs with tight tolerances, ensuring compatibility with legacy and next-generation defense platforms. The contractor has delivered casting solutions exclusively to the Department of Defense, supporting both legacy and modernized weapon systems through custom-fabricated components used in mechanical assemblies and structural housings. Their work aligns with defense supply chain requirements for traceable materials, certified heat treatments, and compliance with military drawing standards. Industry focus centers on NAICS 331523 (nonferrous die-casting) and 331512 (steel investment foundries), serving niche segments within defense manufacturing that demand metallurgical precision and batch-to-batch repeatability. The company positions itself as a specialized supplier for small-batch, high-reliability castings, filling gaps where large foundries cannot economically support low-volume defense contracts. SIMPSON TECHNICAL SALES, INCORPORATED is a small, privately held business based in Aliquippa, Pennsylvania, with no active government certifications. Its geographic footprint is localized, yet its production capabilities are tailored to meet the exacting standards of federal defense procurement. The company operates as a focused niche supplier, leveraging regional manufacturing infrastructure to serve specialized DoD requirements without reliance on broad-scale certification programs.
