Custom OEM Manufacturing
Built to Your Exact Specifications

HFI Manufacturing is a true contract manufacturer for OEMs who need end-to-end fabrication — from prototype to production. We don’t just make parts, we manufacture products

Your Product, Our Production Line

Custom OEM manufacturing is more than fabrication — it’s a partnership. HFI serves as an extension of your production team, handling laser cutting, forming, welding, finishing, assembly, and kitting under one roof. One vendor, one invoice, one quality standard.

We work with your engineers from concept through production. DFM reviews during prototyping, process validation for production scale-up, and continuous improvement throughout the lifecycle of your product.

Our Custom OEM Manufacturing Capabilities

Full-service fabrication under one roof — from raw material to finished, kitted product.

Quality

ISO 9001-certified quality system with documented inspections, full traceability, and in-process verification for consistent results from prototype through production.

Cutting

Fiber laser cuts stainless up to 1/2″ with burr-free edges. No secondary deburring required for most food-contact surfaces.

Bending

Hydraulic press brakes with ±0.005″ repeatability. Consistent bends across every part, every run, every day.

Welding

Robotic MIG for high-volume production, TIG for cosmetic and sanitary applications, and stick welding for heavy structural work.

Assembly & Kitting

Sub-assembly, hardware insertion, wiring, labeling, and packaging. Deliver ready-to-ship product that reduces your final assembly time.

Finishing

Powder coating, grinding, polishing, brushing, and passivation. We deliver the finish your product requires — cosmetic or functional.
