What Kso Metalfab does

KSO MetalFab, Inc. is a privately held precision contract manufacturer founded in March 1973 by John and Dora Kuzelka and headquartered in Streamwood, Illinois, near Chicago's O'Hare International Airport. The company operates as a vertically integrated job shop providing precision sheet metal fabrication, CNC and conventional machining, welding (TIG, MIG, spot/projection), mechanical assembly, metal finishing, and engineering support including Design for Manufacture (DFM) consulting and reverse engineering. Its technology base includes Amada ACIES 2515T and HK Laser PL3015-Fiber 3000 Watt laser cutting systems, CNC milling and turning, surface and cylindrical grinding, lapping, coordinate measuring (Mitutoyo BH706 CMM), and Fabrivision digital part scanning, with CAD/CAM software (Metalsoft Fabriwin, Pro-Engineer) and MIE Trak32 ERP providing real-time job tracking.

The business model is project- and contract-based B2B services revenue: KSO sells one-time fabrication and machining engagements plus professional services for DFM and engineering, quoting each engagement through a website request form or direct phone/email contact with a stated 24–48 hour response commitment. Pricing is not publicly disclosed. The company targets equipment manufacturers, government transportation agencies (leveraging DBE/WBE/SBE certifications in more than 30 states plus CCR/Cage Code federal registration), and specialized verticals including security, aerospace/avionics, military, medical, semiconductor, transportation equipment, energy, and POS/kiosk manufacturers. Go-to-market is direct enterprise field sales with no formal channel partners, distributors, or marketplace listings identified in the available data.

Broad incumbents

• Protolabs: Significantly larger digital manufacturing services company offering CNC machining, sheet metal fabrication, injection molding, and 3D printing — overlapping in core capabilities but operating at a fundamentally different scale, speed, and price point.
• Ryerson: Large publicly traded metal processor and distributor with fabrication services; not a direct competitor on custom job-shop work, but represents the broader metals-services value chain and a potential customer for material inputs.

Direct peers

• BTD Manufacturing: Lakeville, Minnesota-based contract manufacturer offering sheet metal fabrication, CNC machining, welding, powder coating, and assembly — a close operational analog to KSO's vertically integrated job-shop model.
• Talan Products: Cleveland-based contract metal manufacturer providing stamping, fabrication, machining, and assembly for industrial OEM customers, directly comparable to KSO in capability mix and customer type.
• Kapco Metal Stamping: Wisconsin-based contract metal stamper and fabricator providing metal stamping, fabrication, and assembly services to industrial customers, comparable to KSO in vertical integration and Midwestern manufacturing services.
• Pro-Fabrication: Sheet metal and structural fabrication services company serving industrial and architectural customers with laser cutting, forming, and welding capabilities overlapping KSO's core offering.
• Tempco Manufacturing: Mid-sized precision sheet metal fabricator offering laser cutting, CNC forming, welding, and assembly to OEM customers — directly comparable in scale, capability set, and customer profile.
