Wenqing Z.

Are you looking for a reliable, highly experienced engineer to bring your hardware concepts to mass production? With over 15 years of robust R&D experience and a Master's degree in Mechanical Design, I help companies and entrepreneurs design high-quality, manufacturing-ready products while drastically reducing prototyping costs through advanced simulation. My engineering background spans across high-precision medical devices (disposable endoscopes), advanced HVAC fluid systems, and heavy-duty industrial hydraulic machinery. I don't just build 3D models; I deliver rigorously engineered, simulation-backed solutions optimized for real-world production. --- ### 🛠️ Core Services I Offer: * **Precision Mechanical & Structural Design:** Specialized in mechanism design, complex component layouts, and electromechanical integrations using PTC Creo and SolidWorks. * **Enclosure & Housing Design:** Expert in designing robust plastic injection-molded housings, sheet metal enclosures, and internal component placements. * **Advanced Simulation (FEA/CFD):** Utilizing Ansys (Fluent/Thermal) and Abaqus to conduct non-linear structural stress analysis, thermal management simulation, and fluid dynamics optimization (airtightness, sealing, and flow channels). * **Design for Manufacturing (DFM):** Comprehensive tolerance stack-up analysis, material selection (polymers/metals), and manufacturing optimization to ensure your parts can be cast, molded, or machined perfectly on the first run. --- ### 🧰 Software Expertise: * **CAD/Modeling:** PTC Creo, SolidWorks, AutoCAD * **Simulation/CAE:** Ansys Fluent, Ansys Mechanical, Abaqus, SolidWorks Flow Simulation --- ### 🤝 Why Work With Me? * **Manufacturing Mindset:** I collaborate directly with toolmakers and understand the realities of the factory floor, ensuring you get real-world deliverables, not just theoretical CAD data. * **Fluent English Communication:** 100% professional working proficiency in English, ensuring clear project scopes, prompt updates, and smooth technical communication. * **Independent & Results-Driven:** Capable of operating as an autonomous engineering consultant to solve your toughest engineering bottlenecks.
