About me

Homam Alhelwani

Mechanical design and development engineer

For around eight years, I have developed, designed and optimised machines and assemblies in Germany's mechanical engineering industry. My experience spans concept development and manufacturing-ready design through to support during manufacturing, assembly and commissioning.

I compare technical approaches and consider function, manufacturing effort, assembly and maintenance — so that the effort and benefits align.

I place particular emphasis on functional and manufacturing-appropriate tolerances, clear technical documentation and close coordination during implementation.

Services

How I can support you.

From the initial idea through detailed design to implementation support: I focus on the tasks that move your project forward.

Special-purpose machine design

Development and design of customised machines, test benches and handling units — from concepts, 3D CAD, manufacturing drawings, parts lists and technical documentation to support during manufacturing, assembly and commissioning. Function, cost-effective production and thoughtful assembly are considered together from the outset.

Tooling & fixture design

Design of tools, vulcanisation moulds and fixtures for clamping, assembly and testing. I consider part geometry, process-related dimensional changes, manufacturing methods and operating requirements — for functional solutions that are economical to manufacture and practical to use.

Prototype development & 3D printing

From a technical idea to a fully designed functional model: I develop prototypes and parts suited to 3D printing to assess space, assembly and function. This includes CAD models, technical documentation and further design development based on manufacturing and test findings.

Engineering services

Engineering calculations, FEM and CFD simulations, and research and development support. For assessing and optimising components and assemblies — with traceable results and specific recommendations for your design.

I support research and development projects from feasibility assessment and concept development to prototypes and experimental fixtures. Test findings feed into further development of the design.

Working together

Direct, personal and structured.

You speak directly with the engineer working on your design task. Scope, interfaces and deliverables are agreed at the outset.

01

Clarify the task

Review function, requirements, interfaces and available documentation together.

02

Develop the solution

Develop concepts and design decisions within the agreed scope.

03

Coordinate the design

Review progress and align function, manufacturing and assembly.

04

Deliver the results

Provide models, drawings and technical documents in a structured form.
