Energy & Power Systems
Fabrication Built for Safety & Performance
HFI Manufacturing fabricates enclosures, cabinets, and structural components for energy storage, power generation, and electrical distribution systems. Built to UL and NEMA standards.
Fabrication for the Energy Sector
Energy and power systems demand enclosures and structures that manage heat, contain batteries, withstand weather, and meet strict electrical safety codes. HFI fabricates components for battery storage, generator sets, switchgear, and solar infrastructure — from prototype to production.
Our team works with your engineers to integrate thermal management, cable routing, and code-compliant labeling directly into the fabrication design, reducing field installation and permitting delays.

Our Energy & Power Capabilities
Fabrication processes designed for the thermal, electrical, and environmental demands of power systems.
ISO 9001-certified quality system with documented inspections, full traceability, and verification to ensure every enclosure and component meets stringent electrical and industry standards.
Fiber laser cuts stainless up to 1/2″ with burr-free edges. No secondary deburring required for most food-contact surfaces.
CNC press brakes handle up to 10ga steel. Consistent flanges for gasket compression and cabinet sealing in outdoor-rated enclosures.
Continuous seam welding for weather-tight enclosures. Robotic MIG for high-volume production, TIG for cosmetic stainless surfaces.
Hinges, latches, ground studs, cable glands, and bus bars installed. Doors aligned and hardware torqued to specification.
Outdoor-grade powder coating in RAL or custom colors. UV-resistant with salt spray testing available for coastal installations.
