Frequently Asked Questions on Product Engineering
What disciplines are included in your product engineering services?
Our catalog covers 12 core mechanical and hardware disciplines: Product Design, CAD Design and Drafting, Engineering Analysis (FEA), Reverse Engineering, Rapid Prototyping, Tooling and Industrialization, Contract Manufacturing, Robotics and Automation, Embedded Systems and IoT, Engineering Outsourcing, Material Handling Engineering, and Sustaining Engineering.
Can we outsource a single engineering deliverable or module?
Yes. Clients frequently engage WENS Engineering for standalone tasks, such as 3D CAD modeling, FEA simulation validation, prototype fabrication, or mold tooling design, without committing to an end to end program. You can also explore our engineering outsourcing models for flexible monthly capacity.
How does WENS Engineering collaborate with in-house R&D teams?
We function as a seamless extension of your engineering department. We participate in sprint standups, adhere to your CAD modeling standards, and provide milestone reviews across North American, European, and Australian time zones. Learn more about our product development process.
What CAD formats and engineering deliverables are provided?
We deliver native CAD files (SolidWorks, Inventor, Creo), neutral formats (STEP, IGES, Parasolid), fully dimensioned 2D manufacturing drawings compliant with ASME Y14.5 GD&T standards, simulation summaries, and structured bills of materials (BOM). Clients retain 100% intellectual property rights.
