R A.

I take products from idea to manufactured reality: concept, mechanical design, DFM, prototype and production files. One experienced engineer, 10+ years, 100+ products designed for production. Most hardware projects stall in the gap between a nice render and a factory-ready part. That gap is where I work. I design parts that molders, machinists and sheet-metal shops can build right the first time, saving you redesign loops, tooling changes and months of delay. ━━━━━━━━━━━━━━━━━━━━ 1) NEW PRODUCT DESIGN & DEVELOPMENT From a sketch, idea or rough prototype to a production-ready product. • Concept development and detailed 3D CAD • Mechanisms: gears, hinges, ratchets, linkages, snap-fits, sliding and locking parts • Consumer products, wearables, fitness equipment, devices and tools • Material and process selection to hit your cost and quality target 2) ELECTRONICS ENCLOSURES & DESIGN FOR MANUFACTURING Housings that fit your PCB, protect it, and pass manufacturing. • Injection-molded parts: draft, ribs, bosses, uniform walls, snap-fits • Sheet metal, aluminium extrusion and 3D-printed enclosures • IP-rated sealing, gaskets, venting and thermal paths • RF-friendly design that keeps antennas working • DFM reviews of your existing design before you pay for tooling 3) PROTOTYPING & MANUFACTURING SUPPORT Getting your design physically made, and made correctly. • Prototype-ready files for 3D printing (FDM, SLA, MJF), CNC machining, laser cutting and welding • Fixing CAD files that vendors reject: merging bodies, repairing geometry, correcting tolerances • Reverse engineering: STL or scan to clean, editable STEP models • Manufacturing drawings that vendors understand without back-and-forth ━━━━━━━━━━━━━━━━━━━━ WHAT YOU RECEIVE Native CAD + STEP files, 2D manufacturing drawings with tolerances/GD&T, BOM, and assembly notes, ready for JLCPCB, PCBWay, Xometry or your own vendor. Full IP ownership is transferred to you. RECENT PROJECTS • RF-transparent outdoor case: designed and prototyped • Power system enclosure with precise internal clearances • Stainless steel sheet-metal electronics enclosure • Production CAD for an injection-molded fitness product • Internal mechanism for a small form-factor device • Fixed a CAD file for 3D printing that the client's own engineer couldn't solve in weeks • Machined and fabricated stainless steel and brass parts for a repeat client WHAT CLIENTS SAY "Aravin promptly solved the CAD merging issue... one that my M.E. couldn't despite weeks of iterations." "I highly recommend R ARAVINDHAN for any custom design and engineering work." WHY WORK WITH ME • Engineer, not just a 3D modeler: I design for how a part is made, assembled and used • Electromechanical background: I design around PCBs, cables, connectors, antennas and heat • Top Rated, 100% Job Success, repeat clients • Clear milestones, honest timelines, quick responses on IST working days TOOLS: SolidWorks, Creo Parametric, AutoCAD Send me your idea, sketch, PCB or existing CAD. I'll reply with an honest assessment of what it takes to make it manufacturable.
