General Manufacturing

Versatile precision machining and assembly for custom tooling and components across diverse general-manufacturing projects.

The design and production of large‐scale machinery, automation systems, and heavy equipment for industrial applications, where reliability and performance are paramount. Adherence to ISO, ANSI, and other applicable standards supports continuous operation under high‐stress conditions, with custom‐engineered systems often required.

Industrial Machinery & Heavy Equipment

Manufactures precision tooling and assemblies supporting automation systems and heavy industrial machinery.

Heavy-duty equipment, wear-resistant components, and downstream smelting or refining systems for mineral extraction and metal production. MSHA safety, abrasion-resistant materials, and harsh-environment design ensure reliable operation in demanding conditions.

Mining, Metals & Minerals Processing

Produces wear-resistant components for harsh mining and minerals-processing environments.

The design, manufacturing, and assembly of components and systems for passenger cars, commercial and off-highway vehicles, rail rolling stock, and emerging electric/Autonomous mobility platforms. High-volume production, IATF 16949 compliance, JIT supply chains, and continuous innovation ensure reliable powertrains, safety-critical systems, and cost-efficient delivery across a broad transportation landscape.

Automotive & Transportation

Delivers precision tooling and components for automotive systems with efficient, quality-focused production.

The design, manufacturing, and integration of high‐precision components, systems, and subsystems for commercial aircraft and military platforms, with emphasis on meeting stringent certifications such as AS9100, ITAR, and MIL‐STD. Priorities include advanced materials, rigorous quality assurance, and robust engineering to ensure reliability in mission‐critical applications.

Aerospace & Defense

High-precision machining and assembly for aerospace and defense platforms, compliant with AS9100D and ITAR.

Rolling-element and plain bearings, linear guides, gear reducers, couplings, belts and associated housings that transmit motion and load in industrial machinery. Manufacturing focuses on heat-treated races, precision grinding, ABEC/ISO tolerances and lubrication channels to ensure long service life under high-rpm, shock and contaminated environments.

Bearings & Power Transmission Components

Supplies grinding quills, raceway tooling, and tight-tolerance parts enabling high-speed, low-noise bearing production.

Involves the design, development, and production of armaments, from small arms to artillery, missiles, and munitions. Requires precision engineering, safety protocols, and compliance with defense export and usage regulations.

Weapons & Ammunition

Manufactures precision fixtures, tooling, and machined components for firearm and ammunition production under strict ITAR controls.
