Hire the Best Siemens NX Specialists
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.

Mechanical engineer who specializes in mechanical design and analysis. I have experience and projects in mechanical design and analysis in the automotive and defense industries. I usually use Catia v5, SolidWorks, and Ansys.I also have experience with Siemens NX, Inventor, and AutoCAD. areas of expertise: -Mechanical Design With the CAD design experience I gained in sectors such as the defense industry or automotive, I have advanced solid modeling and surface modeling competence on moving systems and static models. I usually use Catia V5 or SolidWorks, and I also have experience with Inventor and NX -Computer Aided Analysis I have experience and studies on aerodynamic and fluid thermal systems analysis with CFD, strength analysis with static analysis, and analysis of moving systems with dynamic analysis (with thesis).

Mechanical Design Engineer with 13+ years of professional experience delivering production-ready designs in SolidWorks and AutoCAD on time, every time. ✔ 100% Job Success Score ✔ Top Rated Plus — top 3% of talent on Upwork ✔ Available now — 30+ hrs/week I hold dual engineering degrees in Mechanical Engineering and Metallurgy & Materials Engineering, which gives me a rare combination of design precision and deep materials knowledge. I work with manufacturing companies, fabrication shops, and product development teams across the US and Australia to transform concepts into shop-floor-ready documentation. My deliverables include fully detailed 3D models, fabrication drawings, DXF/STEP files, and complete BOM packages no back-and-forth, no rework. Core expertise: ▸ Trailer & mobile equipment — custom trailers, food trailers, utility trailers, scissor lifts ▸ Welded steel structures — frame design, load analysis, structural calculations ▸ Sheet metal & CNC — DXF-ready flat patterns, bend allowances, nesting optimization ▸ FEA (Finite Element Analysis) — static, fatigue, and structural simulations to validate designs before fabrication ▸ Industrial machinery — hydraulic systems, water treatment equipment, reverse engineering ▸ DFM reviews — catching manufacturability issues before they reach the shop floor What sets me apart: Most designers model what you ask for. I go further — I validate it. My dual background in mechanical engineering and metallurgy means I understand how materials behave under real-world loads, how welds perform under fatigue, and how to optimize designs for both structural integrity and cost-effective manufacturing. Every critical design I deliver is backed by FEA analysis, not just experience. I respond to all messages within 4 hours and provide clear project milestones from day one. You'll always know where your project stands.
