Mantel Machine Products Inc.

Mantel Machine Products Inc., a for-profit Subchapter S corporation manufacturer headquartered in Menomonee Falls, Wisconsin, with an additional facility in Los Alamitos, California, specializes in the design and manufacture of precision mechanical components and assemblies for defense applications. Registered in SAM.gov since November 22, 2022, the company is classified as a small business, woman-owned business, and manufacturer of goods. Mantel Machine Products serves as a prime contractor to the U.S. Department of Defense, primarily through the Defense Logistics Agency (DLA) and its sub-agencies, supplying critical mechanical hardware essential to military vehicles, aircraft, vessels, and weapons systems across various platform types and operational requirements.

Mantel Machine Products has demonstrated extensive capability through a substantial portfolio of prime federal contract awards spanning multiple years. The company's product offerings include a diverse array of mechanical fasteners and components such as pins (straight-headed, shoulder-headed, grooved-headed, and headless variants), shafts (shouldered and standard configurations), nuts (plain round, steering brake, and helical compression seats), bolts (eye bolts and fluid passage bolts), bushings, sleeves, spacers, adapters, keys, couplings, guides, valves (bleeder and other hydraulic/pneumatic types), clamps, manifolds, covers, plugs, studs, handles, clevis rod ends, extension screws, latch mechanisms, and various other specialized mechanical assemblies. Contract awards have been funded primarily through DLA Aviation, DLA Land and Maritime, and DLA Troop Support divisions, with the vast majority structured as firm fixed-price purchase orders and delivery orders. Individual contract values have ranged from under $1,000 to more than $441,000, with most awards falling between $1,500 and $7,500. While the company primarily operates as a prime contractor without identified major subcontractors, several contracts have included small business set-aside designations, including total small business set-asides for procurements such as spacer rotor drive components, locking trigger latches, grooved headless pins, and various other mechanical parts. Recent awards spanning from 2023 through October 2025 demonstrate consistent engagement with the Defense Logistics Agency across multiple product categories and delivery requirements.

Mantel Machine Products Inc. currently maintains two active Indefinite Delivery Contracts (IDCs) with the Defense Logistics Agency, both designated as total small business set-asides. The first IDC, awarded by DLA Aviation on January 22, 2025, carries a ceiling value of $250,000 with an ultimate completion date of January 22, 2026, and procures adapters and torsion bar mechanical components for use across various military platforms and defense logistics operations. This contract was established following a Request for Quotation solicitation posted in November 2024 with projected requirements for approximately four orders annually and a guaranteed minimum quantity of 14 units, with primary manufacturing occurring at the Menomonee Falls, Wisconsin facility. The second IDC, awarded by DLA Aviation on April 30, 2024, carries a ceiling value of $250,000 with an ultimate completion date of April 29, 2029, and covers a broader portfolio of critical mechanical components including pins, shafts, keys, nuts, bolts, couplings, and hydraulic/pneumatic parts. This longer-term contract vehicle has been actively utilized through multiple delivery orders for specialized spacers used in rotor drive systems, with individual task orders valued between approximately $3,233 and $3,571. Both IDCs are structured to enable the Defense Logistics Agency and its sub-agencies to efficiently procure diverse mechanical components necessary for military applications while providing Mantel Machine Products with predictable volume commitments and sustained business opportunities within the defense supply chain.
