Hire the Best Automotive Design Freelancers
in Turkey

www,celalettintoprak,com I design real products that get manufactured - not just 3D models. Manufacturing-ready CAD, prototyping, and Design for Manufacturing (DFM)-driven product development for industrial and consumer products. I’m an Engineer and Industrial Product Designer focused on manufacturing-driven product development. My background spans automotive, industrial, and consumer products, where I’ve worked as a Product Developer, Designer, and Technical Lead in production-oriented environments. I don’t approach projects as isolated design tasks. I approach them as systems that must survive prototyping, manufacturing, assembly, cost pressure, and real-world use. 📐 What You Can Expect Working With Me: - Clear, structured CAD suitable for iteration and production - Design decisions informed by manufacturing reality - Practical communication with engineers, suppliers, and manufacturers - Honest feasibility feedback (go / no-go when needed) - Designs meant to be tested, not just rendered 📐 Core Capabilities: - 3D CAD modeling (Siemens NX) - 2D technical drawings (AutoCAD Professional) - CNC, laser cutting, and sheet metal preparation - Injection molding–ready part design - Fixture, bracket, and assembly design - BOM creation and production planning support - Reverse engineering and scan-based modeling 📐 Injection Mold & Manufacturing Experience I have hands-on experience designing plastic injection molds and mold-ready parts, including projects for automotive and food-related products. ⚙️ I’m familiar with: - Injection molding–ready design, Core / cavity logic - Draft angles & wall thickness optimization - Parting lines and shut-off surfaces - Shrinkage and material behavior - Gate concepts (hot runner, valve gate) - Collaboration with mold makers and CNC shops - Design for Assembly (DFA), production validation - Engineering-driven product development - Long-term product roadmap support My focus is always on tool longevity, cycle time, surface quality, and cost efficiency. 📏 Typical Projects I Work On: - Automotive accessories and aftermarket products - Mechanically complex plastic or metal parts - Prototyping-heavy product development - Production validation before tooling - Redesigns for cost reduction or manufacturability - CAD clean-up and production conversion 📌 Primary CAD Tool: Siemens NX, AutoCAD and Geomagic Design X I work primarily in Siemens NX, which is widely used in high-end automotive and industrial manufacturing. I can deliver clean, fully editable STEP / STL / Parasolid files, and I regularly convert and work with SolidWorks, Fusion 360, Rhino, SketchUp, and scan-based data. If you use SolidWorks or another CAD system, this is not a limitation — deliverables are always production-ready and compatible. 📌 If you need more than a modeler—someone who understands how products are actually built and scaled—I can support your project from concept to production readiness.
