Hands-On Product Engineering for Complex, High-Stakes Products
Our product engineering team bridges the gap between concept and production. Once you're satisfied with initial concepts, our mechanical and electrical engineers create detailed parametric 3D design files and select materials and components that meet your performance and production goals.
DEM’s Mechanical and Electrical Engineering Design Process
When a product involves electronic components, our mechanical and electrical engineers work in tandem to optimize both functionality and internal layout. This collaboration allows us to build tightly integrated systems that meet performance demands without sacrificing design constraints.
Speed matters, so we’ve built a process that supports it.
Our team can source custom printed circuit boards in as little as 24 hours to keep development moving.
Once the circuitry is designed, laid out, and refined, we finalize the form factor and key components before moving directly into tooling design.
Design for Manufacturing (DFM) Bridges the Gap Between Concept and Efficient Production
Our team of design engineers, quality control, manufacturing personnel, and manufacturing engineers evaluates new product designs to ensure they can be built and inspected as efficiently as possible.
This collaborative DFM process ensures that each product:
- Avoids unnecessarily complex build steps
- Aligns with standard equipment and in-house capabilities
- Incorporates quality checks for downstream inspection
- Maintains performance and reliability across environments
Feedback is integrated throughout the engineering phase, so your product moves forward without costly delays or redesigns.
Where Precision Design Meets Scalable Production
As a turnkey product engineering and manufacturing partner, DEM designs both products and the tooling with production in mind from the start. Every product is evaluated for fit, form, and function before final design release to reduce the risk of downstream issues. This phase also includes final DFM checks, comprehensive product validation, testing for standards like MIL-STD-810, and the creation of detailed documentation to support repeatable, cost-effective production.
In addition, we run full assembly rehearsals using 3D prototypes that allow us to verify alignment and integration before production begins.
This phase ends with a complete documentation package, including detailed CAD drawings, specifications, a bill of materials (BOM), and preliminary work instructions to support First Article (FA) production.

What DEM’s Product Development Process Looks Like
From the first sketch to production-ready tooling, DEM’s integrated development process helps you move faster, with fewer risks and more visibility. Our typical process includes:
-
Initial consultation: Define product requirements, performance goals, and regulatory standards.
-
Concept creation: Develop early sketches, 3D CAD models, and assemblies for initial design reviews.
-
Concept prototyping: Produce basic 3D-printed models to gather early-stage feedback.
-
Design for Manufacturing (DFM) review: Conduct cross-functional reviews to simplify builds and optimize for production.
-
Detailed design development: Finalize PCBA layout, material selection, and mechanical structure.
-
Rapid prototyping and iteration: Refine the design through performance-driven updates.
-
Confidence testing: Execute internal, client-led, or third-party testing to confirm performance and reliability.
-
Production tooling and assembly process development: Prepare molds, jigs, and workflows for efficient production.
-
Production documentation: Generate work instructions, QC protocols, and training materials.
-
Handoff to manufacturing: Launch regular production with established quality and process controls.
Our team’s deep experience ensures a smooth transition from prototype to full production—without sacrificing quality or speed.
