Production-Ready Mechanical Design
We design production-ready mechanical systems that are robust, manufacturable, and tightly integrated with electronics. From early concept and enclosure design to tolerance analysis, DFM, and production handover, POLR supports mechanical development for hardware products built to scale across Europe and beyond.
We develop production-ready mechanical designs for hardware products—covering enclosures, internal assemblies, mounting features, material selection, and DFM. From early concepts to manufacturing handover, POLR supports international teams delivering reliable, scalable mechanical solutions.
What we do
-
Mechanical concept & system architecture (product layout, constraints, integration strategy)
-
Enclosure & housing design (plastic, metal, sealed and non-sealed designs)
-
Internal structures & mounting solutions (PCB mounting, fasteners, alignment features)
-
Tolerance analysis & stack-up (fit, assembly robustness, repeatability)
-
Material selection (plastics, metals, elastomers based on cost, strength, environment)
-
DFM/DFA optimization (design for manufacturing & assembly)
-
Thermal & mechanical considerations (heat dissipation, airflow, structural integrity)
-
Prototyping support (3D printing, CNC, early-fit verification)
-
Manufacturing documentation (drawings, BOMs, assembly instructions)
-
Production handover support (factory alignment, revisions, manufacturing feedback)
Manufacturing methods supported: injection molding, CNC machining, sheet metal, and additive manufacturing—depending on product requirements.
Why POLR Engineering
-
Manufacturing-first mechanical design: DFM and DFA decisions are considered from the first CAD concept
-
Electronics-aware mechanics: mechanical designs built to integrate cleanly with PCBs, sensors, and wiring
-
Faster iteration cycles: clear prototyping, fit checks, and structured design revisions
-
Production alignment: drawings, tolerances, and assemblies prepared for manufacturing handover
-
Scalable designs: mechanical systems optimized for durability, assembly efficiency, and cost at scale
