SELMAX CORP.

SELMAX CORP. specializes in precision injection molding and custom plastic component manufacturing for high-security federal applications, with deep expertise in producing bullion packaging, coin holders, lens capsules, and specialized tubes and caps for U.S. Mint operations. The company’s technical capabilities include mold design, cavity modification, latent defect remediation, and economic price adjustment compliance within long-term government contracts. Their work demands stringent dimensional tolerances, material purity, and anti-tamper features, indicating proficiency in thermoplastic processing, cleanroom-compatible molding, and traceable production protocols for precious metal containment systems. SELMAX demonstrates consistent ability to execute complex mold modifications and maintain production continuity under evolving Treasury specifications, suggesting strong engineering support, quality control systems, and supply chain reliability for mission-critical government components. The contractor maintains an exclusive and sustained relationship with the Department of the Treasury, specifically supporting the U.S. Mint’s physical security and packaging infrastructure. All awarded work centers on the production and maintenance of plastic components used in the storage, transport, and presentation of bullion, coins, and numismatic items, indicating a trusted role in securing national currency assets. This long-standing partnership reflects deep familiarity with Treasury’s operational requirements, procurement cycles, and quality assurance standards for high-value physical assets. SELMAX operates under NAICS 326199, focusing on specialized plastics manufacturing outside standard consumer or industrial categories. Their niche lies in government-grade, low-volume, high-integrity plastic products—particularly those requiring anti-counterfeiting features, non-reactive materials, and precision fit for precious metals. This positions them as a niche supplier within the federal security and minting supply chain, distinct from mass-market plastic manufacturers. As a small business structured as a 2L entity based in Selinsgrove, Pennsylvania, SELMAX CORP. maintains a focused geographic footprint with no federal certifications listed. Their market positioning is defined by technical specialization rather than broad certification portfolios, serving as a mission-critical supplier to a single, highly regulated federal customer.
