Greene Group Industries

What Greene Group Industries does

Greene Group Industries is a U.S.-based, vertically integrated precision components contract manufacturer serving regulated and performance-driven OEMs in medical device, defense and aerospace, commercial and industrial, and electronics and communications markets. The company operates three U.S. facilities totaling 127,000+ square feet in Oceanside, California (corporate headquarters and full-scale production), Port Huron, Michigan (MIM/CIM and Micro-MIM center of excellence with plastic overmolding), and Newark, California (PureForm metal 3D printing development and sales), and employs 275+ people with capacity to produce tens of millions of parts annually.

The company's core technical platform spans metal and ceramic injection molding (MIM/CIM), its proprietary PureForm DLP-based metal 3D printing process (producing MPIF-35 compliant parts with MIM-like microstructures), Micro-MIM for ultra-thin-wall components, precision CNC machining with 60+ machines, precision metal stamping, plastic overmolding, automated assembly, and in-house mold design and manufacture. This capability stack is offered as a single-source, prototype-to-production model targeting complex geometries, tight tolerances, and miniaturized features that conventional machining or casting cannot cost-effectively produce, and is qualified to ISO 9001:2015, ISO 13485, and AS9100.

GGI generates revenue through project-based custom quotes tied to part complexity, material, volume, and process mix, typically delivered under multi-year contracts with enterprise OEMs. GTM is consultative field sales with dedicated project and program managers supporting engineering collaboration on design for manufacturability. The company was acquired by private equity firm Tinicum in 2023 and completed the acquisition of Holo in March 2024 to extend its additive manufacturing footprint. Named customers include Medtronic, Intuitive Surgical, Northrop Grumman, and General Dynamics.
