We construct parametric 3D CAD models of parts and assemblies – planned around manufacturing at the initial sketch - not as an add-on.
A quick review of a design against actual manufacturability-drawing angles, wall thickness, tool accessibility, fastener quantities-before tooling begins.
We engineer sheet metal and molded enclosures that precisely fit your PCB, connectors and thermal considerations. This includes bend clearance, ventilation design and mounting hole locations.
We apply draft angles, wall thicknesses, internal rib details and the perfect gate/parting line strategies when designing plastic parts for injection molding to assure trouble-free production.
FEA structural analysis along with thermal simulation analysis are employed to identify weaknesses early before the design is committed to tooling - preventing both field failure and thermal issues in electronic products.
By creating physical prototypes and 3D printed part samples, we are able to verify form, fit and function before investing inexpensive production tooling. It allows for iteration so what “isn't” works can quickly be identified and improved.
We make precise copies of physical parts and assemblies from 3D scanned data to provide you with highly accurate CAD models and manufacturing drawings; great for cases where drawings are lost or modification is required.

Representative examples of the kind of mechanical design work we take on.
Problem: The current sheet metal enclosure had many bends and fasteners, making the per-unit cost high. Solution: Designed with less bending, standard hardware and improved material utilization. Effect: Achieved cost reduction in fabrication and assembly without altering the exterior shape of the enclosure.
Problem: Consumer product housing had sink marks and warpage issues in its initial mold trial. Solution: Modified the wall thickness, corrected ribs and gate location using flow simulation. Effect: The mold trial performed successfully in terms of dimensions and cosmetics in its very first attempt without needing another tooling cycle.
Problem: Verify whether the redesigned industrial equipment frame will be able to withstand the rated load with light material. Solution: Conducted structural FEA in all expected load cases and modified ribs and gussets in the simulations. Effect: Frame was able to withstand rated loads with less weight, without fabricating the steel component physically.
RhoSigma supports the transition from mechanical design to manufacturing by providing DFM reviews, prototype support, drawing and documentation preparation, design optimization, and production assistance. Our goal is to ensure that mechanical designs are practical to manufacture, assemble, test, and scale.
Review and optimize mechanical designs for manufacturability, material selection, tolerances, tooling, and production requirements.
Support prototype builds to validate dimensions, fit, functionality, assembly, and mechanical performance before production.
Prepare detailed engineering drawings, dimensions, tolerances, BOMs, and manufacturing documentation for production teams.
Provide engineering support during vendor discussions, manufacturing reviews, component sourcing, and production preparation.
Identify manufacturing issues and recommend design improvements to reduce production challenges, improve quality, and support scalable manufacturing.
A mechanical design is an engineering process that entails the creation of a product idea by defining its geometry, materials, tolerances, and assembly approach in order to create a part or a product that is functional, can be assembled, and withstands everyday use. This can be a simple machined bracket or even a complex enclosed housing for an electronic product made up of several subassemblies. Good mechanical design goes beyond being a 3D CAD model, as it must incorporate all aspects of manufacturing, assembly, and usage of the product, hence the inclusion of design-for-manufacture reviews at every step in the process.
Questions we hear on every mechanical design scoping call — answered directly, without the brochure language.

Yes. Rhosigma can design sheet metal, injection molded, or die cast enclosures to fit existing PCBs, connectors, and desired thermal performance, including a DFM review for the most appropriate manufacturing process.
Yes. Rhosigma utilizes FEA for structural loading and thermal simulation for heat dissipation to help validate a design prior to commitment to tooling or prototype builds.
A sheet metal or simple enclosure design typically takes 3–5 weeks, whereas a full product design (concept to prototyping to manufacturing drawings release) will typically take 2–4 months depending on complexity and analysis requirements.
Rhosigma uses SolidWorks, Autodesk Fusion 360, and PTC Creo, as well as CATIA, for CAD modeling and also utilizes ANSYS and SolidWorks Simulation for structural and thermal analysis, delivering GD&T-compliant engineering drawings in accordance with ASME Y14.5.
Yes. Rhosigma can reverse-engineer existing parts and assemblies into 3D CAD models and mechanical drawings, often beneficial for legacy parts or when original design files are lost.
