What Prince Industries does

Prince Industries, founded in 1959 and headquartered in Carol Stream, Illinois, is a precision contract manufacturer producing CNC-machined components and sheet metal fabricated parts for enterprise OEMs in aerospace, medical device, and general industrial end-markets. The company operates seven manufacturing facilities across Illinois (Carol Stream, Batavia), Florida (Titusville, Tampa), Vermont (Brattleboro), Massachusetts (Pepperell), and Shanghai, China, with capabilities spanning multi-axis CNC milling, Swiss turning, mill/turn, CNC EDM, precision grinding and honing, long-bar horizontal milling, sheet metal laser cutting, forming, welding, and in-house powder coat painting. Quality certifications include AS9100 (held by five facilities), ISO 13485 for medical devices, ISO 9001:2015, and ITAR registration at Pepperell, complemented by expertise in high-temperature alloys such as titanium, Inconel, and stellite.

A portfolio company of HC Private Investments (HCPI), with Isleworth Capital Partners as co-investor, Prince has executed an acquisition-driven expansion under private-equity ownership, completing four deals between December 2022 and September 2024: Precision Shapes (Titusville, FL), Vulcan Machine (Tampa, FL), Bradford Machine (Brattleboro, VT), and Keystone Precision & Engineering (Pepperell, MA). Each acquired entity retains operating identity under the Prince umbrella and brought incremental AS9100-certified aerospace capacity, with Keystone adding rapid 3D-printed prototyping, thermal enclosures, and box build assembly, and Bradford deepening medical device capability. Prince also operates the QP Hydraulics division, established in 2006, which manufactures hydraulic and electronic joysticks and check valves for mobile and industrial hydraulics markets.

The commercial model is enterprise field sales: quote-based, project-priced contracts with Net 30 standard terms and no publicly disclosed pricing. Prince positions itself as a strategic supply chain partner offering built-in supplier consolidation across multi-process requirements, supported by early-stage engineering collaboration, value engineering, and design-for-manufacturability services. Demand generation runs through a content-marketing website, hosted webinars on aerospace automation, CMMC cybersecurity, and Model-Based Enterprise digitalization, and a structured discovery-call sales intake that funnels enterprise aerospace, medical device, and industrial buyer interest.

Direct peers

• Mayville Engineering Company (MEC): Diversified precision metal fabrication and machining supplier serving industrial, aerospace, and military markets from multiple US facilities. Most directly comparable to Prince as a multi-site, multi-process contract manufacturer with similar customer verticals.
• NN Inc. Precision engineered components and assemblies serving aerospace, medical, and industrial end markets. Comparable in multi-process precision manufacturing, regulated-industry certifications, and customer profile.

Broad incumbents

• Ducommun Incorporated: Established aerospace structural components and electronic systems supplier with AS9100-certified machining capabilities. Significantly larger than Prince but competes for similar tier-2 aerospace machined parts programs.
• Triumph Group: Major tier-1 aerospace structures, precision machined components, and systems supplier. Competes with Prince in machined aerospace components but at a meaningfully larger scale and broader systems scope.
• Protolabs: Digital manufacturing service provider offering CNC machining, sheet metal, and injection molding with rapid lead times. Overlaps with Prince's machining and prototyping capabilities, though Protolabs is platform/digital-led rather than relationship-led.
• Magellan Aerospace: Aerospace components manufacturer with capabilities in complex machined parts and assemblies. Comparable in AS9100-certified aerospace machining but operates at materially larger scale and broader product scope.
• RBC Bearings: Precision-engineered bearings and components manufacturer serving aerospace, defense, and industrial markets. Comparable in precision-machined component capability and regulated aerospace certifications but specialized in bearing products.

Emerging players

• Velo3D: Metal additive manufacturing provider serving aerospace and defense customers with complex geometries. Compares as an emerging alternative to traditional precision machining for certain high-value aerospace parts where Prince's EDM and 5-axis capabilities are relevant.
• Xometry: On-demand manufacturing marketplace connecting buyers to a network of CNC machining and sheet metal suppliers. Indirectly comparable to Prince as alternative sourcing channel for buyers of precision machined components.
• Fictiv: Digital manufacturing platform offering CNC machining and sheet metal fabrication services. Comparable in precision machining offering but competes through a marketplace model rather than direct enterprise relationships.
