Midwest Machining Solutions

What Midwest Machining Solutions does

Midwest Machining Solutions LLC is a privately held, precision machining and metal fabrication job shop headquartered in a 25,000-square-foot facility on North Broadway in Saint Louis, Missouri. Founded in July 2001 by Dave and Lisa Kilwin as a two-person operation in a two-car garage, the company has grown organically to 30 employees without external capital, sales staff, or marketing programs — all demand is sourced through reputation and word-of-mouth referrals. Its service portfolio spans CNC horizontal and vertical milling, CNC turning, manual milling and turning, five-axis waterjet cutting, large-diameter turning with live tooling, metal fabrication (weldments and conveyors), MIG/TIG/stick welding, gearbox repair and rebuild, and stocking of metric and standard keyed shafting, with machining tolerances documented from +/- 1/64" down to .0005" on materials ranging from mild steels to exotic alloys.

The business operates a one-stop, project-quoted model: each engagement is custom-priced based on specifications, materials, complexity, and turnaround, with no standardized tiers or subscription product. Customers are split across six verticals — industrial manufacturing (primary), construction, medical and pharmaceutical, food and beverage, government and military, and heavy industrial — and include Fortune 500 manufacturers alongside regulated buyers benefitting from the company's WBE (Women's Business Enterprise) certification. Geographic reach is concentrated in the St. Louis metropolitan area across roughly ten cities in Missouri and Illinois; distribution is exclusively direct via phone and website contact, with no resellers or marketplace presence.

Operationally, the company's advantage rests on a multi-capability, journeyman-driven shop floor: each machinist programs, sets up, and machines their own parts, supporting diverse, low-to-high complexity work in a single facility. The company has weathered a major customer bankruptcy and multiple economic cycles while continuing to expand capacity, and is currently scaling toward a stated target of 50 employees on the same ownership and organic-growth footing.

Direct peers

• BTD Manufacturing: BTD Manufacturing is a Midwest-based metal fabrication and machining company serving industrial OEMs with welding, laser cutting, and forming services. It is one of the closest regional analogues to Midwest Machining in scope, customer mix, and operational scale.
• MFG.com: MFG.com is an online marketplace that connects buyers with custom manufacturers for CNC machining, fabrication, and related processes. It serves the same customer need (outsourced precision machined parts) that Midwest Machining addresses directly through its St. Louis facility.
• Fictiv: Fictiv is a digital manufacturing platform offering CNC machining, injection molding, and fabrication services through a curated network of vetted machine shops. It competes head-to-head with Midwest Machining for the same custom machined parts and quick-turn production work, primarily via instant online quoting.
• Xometry: Xometry is an on-demand manufacturing marketplace that matches customers with CNC machining, fabrication, and related metalworking service providers. It directly competes with Midwest Machining for outsourced custom parts work, though it does so via a digital marketplace rather than a single owned shop.
• Plethora: Plethora is a U.S.-based precision machining and sheet metal fabrication service provider with a focus on rapid-turn, custom parts for industrial customers. It mirrors Midwest Machining's combination of CNC machining and fabrication services, with comparable tolerance and material capabilities.

Broad incumbents

• Protolabs: Protolabs is a large, publicly traded digital manufacturer offering CNC machining, sheet metal fabrication, and injection molding with automated quoting. It overlaps heavily with Midwest Machining's core CNC and fabrication capabilities but operates at national scale with proprietary software and a much broader service portfolio.
• Shape Technologies: Shape Technologies is a leading global supplier of waterjet cutting systems and contract waterjet cutting services. It overlaps with Midwest Machining's five-axis waterjet cutting service line as a larger, technology-owning incumbent with both equipment and service exposure.
• O'Neal Manufacturing Services: O'Neal Manufacturing Services is a large U.S. metal fabrication company offering plate processing, machining, welding, and assembly across multiple facilities. It competes with Midwest Machining in industrial fabrication and machining but at meaningfully larger scale and with a national footprint.
