Power-Transmission Components

Riveting uses a metal pin with a head, deforming or 'bucking' the opposite end to fasten materials together, common in aerospace and structural assemblies.

Riveting

Computer-controlled vacuum, atmosphere, salt-bath and induction furnaces provide hardening, carburizing, nitriding, solution aging, annealing and stress-relief cycles up to 2 000 °F with ±5 °F uniformity. Integrated quench systems (oil, polymer, inert gas) and real-time FNC sensors ensure repeatable microstructure, case depth and dimensional stability per AMS 2750G.

Heat-Treating & Thermal Processing

Precision Roller Chain Manufacturing

Design and supply of agricultural and heavy-duty conveyor chains engineered for elevated load and environmental exposure. Product families feature robust link geometries, abrasion- and corrosion-resistant finishes, and configurations sized for bucket elevators, conveyors and agricultural drives. Documentation covers installation, maintenance and specification selection to support OEM integration and aftermarket replacement requirements.

Conveyor Systems & Modules

Powder Coating is a dry finishing process where a powder material is applied to a metal surface, then cured under heat to form a hard, protective layer. This coating is durable, corrosion-resistant, and available in many colors, making it popular in automotive, appliance, and consumer goods industries.

Powder Coating

Rolling passes metal stock through one or more pairs of rolls to reduce thickness, ensure uniformity, and achieve desired mechanical properties.

Rolling

Agricultural & Industrial Chain Solutions

Supply of specialty chain components and assemblies for environmental and bulk-handling applications, including auger and conveyor-drive interfaces. Offerings focus on high-wear flight and shaft components, abrasion-resistant materials and optional hard-faced finishes to extend service life. Product variants are documented for material compatibility and configured for OEM retrofits and process-specific longevity requirements.

A product-family covering all modular components used to build screw-type bulk-material conveyors—including complete conveyor screws, ribbon screws, blender/mixer screws, shafts, couplings, hangers, and wear shoes.  Components are supplied in carbon, stainless, or specialty alloys and may feature sectional or helicoid flight construction, hard-facing, dynamic balancing, and turnkey machining for ready installation.

Screw Conveyor Components

Cold Working comprises metal forming processes carried out below the metal’s recrystallization temperature. It increases strength and hardness through plastic deformation methods like cold rolling, cold forging, and cold drawing.

Cold Working

Corrective leveling with 17–23 staggered work rolls and hydraulic backup flights, removing coil set and cross-bow to achieve flatness ≤0.003 in·ft⁻¹ for laser or stamping stock.

Precision Roller Leveling

Environmental & Specialty Chain Components

Production of sprockets and matched power-transmission hardware using CNC machining and controlled finishing. Deliverables include hardened tooth profiles, keyed and taper-lock bores, and matched-bore assemblies sized to AGMA/ISO conventions. Components are supplied as matched sets for roller-chain drives and power-train installations with material and finish options documented for interchangeability and service conditions.

Design, manufacture and alignment of complete drive-trains—including cast or fabricated girth gears, precision-machined pinions, drop-in gearboxes, fluid couplings and high-efficiency motors—supplied as matched sets with torque-arm bases and lubrication systems, then installed and laser-aligned on site.

Rotary Drive-Train Manufacturing & Integration

CNC Machining is subtractive manufacturing performed on computer-numerically controlled machine tools. Toolpaths generated from CAM drive multi-axis milling, turning, and mill-turn equipment to remove material accurately and repeatably. The approach enables tight tolerances, stable process capability, and scalable automation for prototypes through production across metals and engineering plastics.

CNC Machining

Metal forging compresses heated billets between open-die hammers, closed-die presses or hydraulic up-setters to refine grain flow, eliminate porosity and enhance fatigue life. Equipment ranges from 1,500-lb hammers to 6,000-T hydraulic presses, producing parts up to 10,000 lb with ±0.010 in die-impression accuracy.
