Engineering
Partnership
One team. One roof. One timeline. Our in-house engineering, design, and manufacturing teams work as a single turnkey operation — turning custom projects on in days instead of weeks. A full custom shop, in-house and at your service.
Design Engineering
Custom-engineered from the ground up for your specs, your footprint, and your process. Our design engineers work alongside you from concept through release to optimize for lead time, performance, and cost so every system is purpose-built for the job it has to do.
Design for Manufacturing (DFM)
We engineer builds that are faster to produce, easier to scale, and cleaner to assemble without compromising quality or performance. DFM reviews happen early, so manufacturability is designed in from the start rather than engineered around later.
Design for Assembly (DFA)
Assembly-aware design that cuts build time, reduces error rates, and eliminates integration surprises on the floor. Every assembly is engineered to come together predictably so production stays on schedule and the system you get matches the system you spec'd.
Commissioning
On-site startup, validation, and system handoff quickly get your equipment live. Our expert technicians and engineers in power, control, and mechanical systems ensure commissioning is a smooth launch, not a bottleneck.
Testing
Comprehensive environmental stress screening (ESS), functional testing, and performance validation on every assembly before it ships. We find the failures in our facility so you don't find them in yours.
Prototyping
Rapid prototyping to pressure-test your design before you commit to production. Whether it's a first-article build, a proof-of-concept, or a short-run pilot, we turn prototypes in days so design decisions happen with real data, not assumptions.
Feasibility Studies
Early-stage engineering reviews that validate concepts, stress-test assumptions, and de-risk your timeline before capital is committed. We help you answer the hardest questions early: cost, schedule, manufacturability, compliance, so the project you launch is the project you can actually deliver.
Certifications
Engineered to the standards your industry demands. UL, IPC-A-610, IPC/WHMA-A-620, ISO 9001:2015, ITAR, IATF 16949, and WHMA, with the documentation, traceability, and process controls to prove it on every build.
Built in Baltimore.
