Custom Engineering Concepts turns concepts into precision parts and products — across automotive, aerospace, and technology. From sketch to fabricated, finished, delivered.
Three phases, one team. We carry a project end-to-end so nothing gets lost between idea and execution.
Concept, CAD, and mechanical design. We turn requirements into manufacturable geometry — fixtures, brackets, assemblies, and full products.
Prototyping, fabrication, and iteration. Metal fab, manufacturing, and hands-on validation until the part performs the way it should.
Production, project management, and handoff. Finished hardware, documented and delivered on spec.
Versatile by design — ranging from home automation and graphic design to product development, industrial, and landscape design.
A sample of fixtures, brackets, and assemblies across automotive and aerospace projects.
Custom Engineering Concepts was started by Christian Elmassry in 2005, targeting off-road racing and fabrication — then pivoting toward custom design in automotive, aerospace, and technology.
Before founding CEC, Christian served as a contractor and consultant at SpaceX, Senior Aerospace, Arrowhead Products, Vance & Hines Racing, and Integral Aerospace — bringing flight-grade discipline to every build.
That range is the point: one team that can take a project from napkin sketch to finished, delivered hardware.
