Engineering validation
Validate core function and engineering risks with suitable prototypes before committing to tooling. EVT terminology applies where the product and program warrant it.
Move from Prototype to Production with Confidence
A working hardware or electronics prototype is only the beginning. From Shenzhen, China, Mezz coordinates engineering validation, DFM, BOM and component strategy, supplier qualification, tooling, pilot builds, and production ramp—helping close the gap between “it works” and “we can manufacture it reliably at scale.” Local access helps engineering, supplier, and factory issues move beyond remote communication and into practical investigation.
Manufacturing readiness
From working prototype to manufacturing readiness
Customers may arrive with an early or engineering prototype, existing CAD or PCB files, an old supplier’s build, tooling underway, or a production process already in trouble. Mezz reviews the actual entry point and connects design refinement, manufacturability, component availability, cost, quality planning, and production repeatability. Products still needing integrated engineering can begin with Product Design & Development.
- Coordinate mechanical, CNC, 3D-printed, prototype PCBA, electronics, assembly, and integrated functional prototypes to expose engineering and manufacturing risks before tooling.
- Apply mechanical DFM and electronics DFM/DFT across injection-molded parts, tolerances, materials, process selection, assembly, test, and design simplification to reduce tooling rework, assembly issues, yield problems, and late production surprises.
- Review the BOM against cost targets, component availability, MOQ, lead time, lifecycle risk, alternate components, supplier input, and production continuity.
- Qualify component, PCB/PCBA, prototype, tooling, molding, and assembly suppliers through capability, quotation, quality, capacity, and engineering-response reviews—not price alone.
- Plan tooling DFM, injection mold development where required, mold review, T0/T1/T2 sample learning, engineering corrections, pilot builds, work instructions, fixtures, test procedures, quality checkpoints, yield review, and corrective actions before production ramp.
Launch route
Validate the product and production process stage by stage
Design validation
Confirm performance, DFM/DFT, components, compliance needs, tolerances, materials, assembly, and test. Testing or certification findings must flow back into engineering.
Production validation
Prove through pilot production that the intended suppliers, assembly process, work instructions, fixtures, test procedures, quality checkpoints, and corrective actions can deliver a repeatable build. Stage names vary by project.
Production ramp
As the customer’s engineering and manufacturing execution partner, Mezz coordinates suppliers and factories through ramp-up, issue resolution, change control, test and inspection feedback, and quality monitoring. A transferable engineering package helps avoid unnecessary dependence on one factory.
Have a prototype but no production plan?
Turn the build into a supplier-ready package, with downstream Quality Control & Certification planned before ramp. If a supplier or factory project is already failing, see Supplier Rescue.
