Trondheim is recognized globally as Norway’s technology capital, anchored by the Norwegian University of Science and Technology (NTNU), SINTEF, and St. Olavs University Hospital. The region leads Northern Europe in diagnostic ultrasound, minimally invasive surgical guidance, and autonomous patient monitoring.
Beyond hospital wards, Trondheim is a global nexus for marine engineering, aquaculture automation, and subsea hyperbaric medical chambers. Keypads must survive severe freeze-thaw cycles, high salinity atmospheres, and extreme atmospheric shifts without failure.
Under the European Union Medical Device Regulation (EU MDR 2017/745) enforced in Norway through the EEA agreement, every sub-tier component must provide uncompromised material traceability, RoHS/REACH substance compliance, and UL94 flame retardancy ratings.
How our custom medical-grade keypads deliver uncompromised tactile accuracy and hermetic protection in demanding clinical, research, and marine environments.
Trondheim’s world-renowned ultrasound engineering sector demands low-profile, wipe-clean consoles that integrate seamlessly into complex ergonomic housings. Our custom PET membrane assemblies provide back-printed dead-front indicator zones, anti-glare finishes for brightly lit operating theatres, and perimeter sealing that prevents ultrasound gel, bodily fluids, and enzymatic detergents from seeping into internal electronics.
Decentralized healthcare across rural Trøndelag requires ruggedized, portable diagnostic terminals. Utilizing high-durability silicone rubber keymats molded over silver flexible circuits, our interfaces maintain elastic snap-back characteristics in sub-zero winter temperatures, enabling paramedics and field nurses to execute critical medical actions while wearing thick protective gloves.
At NTNU’s departmental labs and SINTEF biotechnology pilot facilities, keypad surfaces endure repeated cleanings with harsh solvents such as acetone, 70% isopropanol, and sodium hypochlorite. Our multi-layer polyester overlays with anti-microbial silver ion matrices permanently inhibit bacterial colonisation and prevent surface embrittlement or legend fading over millions of touch cycles.

Four mega-trends reshaping human-machine interface requirements across Norway’s medical and industrial sectors.
Hospital infection control boards in Helse Midt-Norge increasingly reject traditional mechanical switches with particulate-trapping crevasses. Modern procurement mandates continuous, wipe-clean surfaces. We engineer micro-embossed rim borders (0.3mm to 0.5mm elevation) that grant clinicians the vital tactile confirmation of key engagement while leaving zero crevices where pathogens or sterilizing fluids can accumulate.
With the integration of wireless IoT patient telemetry, high-frequency surgical cauterizers, and robotic magnetic tracking at St. Olavs, electromagnetic interference (EMI) can lead to hazardous phantom actuations. Our engineering incorporates printed full-coverage silver or aluminum shielding grids that shunt electrostatic discharges (up to 15kV ESD) safely to device ground, strictly satisfying IEC 60601-1-2 EMC directives.
Norway’s stringent Miljøfyrtårn and European sustainability regulations demand zero heavy metals and restricted plasticizers. Every adhesive layer (utilizing authentic 3M 467MP/468MP/200MP transfer tapes), conductive Henkel paste, and UV-curable ink in our factory is certified 100% compliant with REACH Annex XVII, RoHS 3 (Directive 2015/863), and Halogen-Free guidelines.
How Zhejiang ZIRA controls every engineering phase in-house to guarantee sub-millimeter registration, durable tactile feedback, and total electrical reliability.
Spectroscopic & thickness audits of Autotex PET films and authentic 3M adhesives.
Gerber and CAD alignment, circuit pitch evaluation, and snap-ratio calculation.
High-mesh tensioned polyester screens exposed for sub-micron line resolution.
Back-printing multi-pass graphics and micro-conductive silver traces.
Precise temperature ramp to ensure polymer cross-linking and zero silver migration.
Automated camera target recognition ensuring ±0.05mm layer-to-layer registration.
Heated CNC steel molds forming pillow, rim, or dome tactile keys without film stretch.
High-tensile crimping of 2.54mm pitch female/male or solder-tab connectors.
Bubble-free integration of overlay, dome retainer, spacer, and rear adhesive.
Ohmic contact resistance, loop insulation (>100MΩ @ 100VDC), and dome snap ratio verification.
Founded in 1996 in Ningbo, Zhejiang, ZIRA has evolved from a specialized panel shop to an internationally accredited HMI manufacturing partner with annual exports reaching over US$30 million.
Full onsite physical verification of production facilities, equipment capability, and QA/QC documentation.
Continuous engineering operation since 1996, supporting complex custom HMI projects from 1-piece pilot runs to mass production.
Longstanding, multi-year supply relationship with industrial automation giants including ABB and Emerson.
Seamless logistics to Trondheim (Værnes / Port of Trondheim) under FOB, CIF, or DDP terms with complete toll documentation.
Direct technical answers addressing regulatory compliance, environmental durability, prototyping, and Norwegian import logistics.
We supply a complete Production Part Approval Process (PPAP) documentation bundle, including full Material Declaration Sheets (MDS), raw film certificates from MacDermid Autotype, adhesive shear data from 3M, and RoHS/REACH SVHC declarations. This substantially reduces the audit burden when submitting technical files to Norwegian notified bodies such as DNV Product Assurance.
Yes. We specify Autotex® AM or XE textured medical polyester overlays with hardcoated, chemically non-porous formulations. These surfaces have been certified against 24-hour spot tests with Virkon, 70%–90% Isopropyl Alcohol (IPA), Chlorhexidine, Sodium Hypochlorite (Klorin), and automated Hydrogen Peroxide Vapor (HPV) cycles without clouding, fading, or edge delamination.
We support fast-track R&D with laser-cut tooling for prototypes. First-article functional samples can be produced and shipped within 5 to 7 working days from final artwork and schematic sign-off. Samples are dispatched via DHL/FedEx Express directly to Trondheim within 3 to 4 transit days.
Silver migration occurs under moisture and DC electrical bias. We prevent this by designing wide dielectric isolation gaps (≥0.5mm) and screen-printing protective carbon or UV-cured dielectric overcoats over all conductive traces. Furthermore, our perimeter hermetic gasket seals paired with waterproof microporous venting membranes equalize pressure differentials without admitting internal condensation.
Unlike rigid volume factories, we offer extreme flexibility: prototypes start from just 1 piece, and standard customized production batches start from 100 pieces. We regularly support DDP (Delivered Duty Paid) shipments directly into Trondheim, taking complete responsibility for Norwegian Tolletaten customs clearance and import documentation.
Yes. We engineer hybrid assemblies combining the 3-dimensional ergonomic tactile stroke of compression-molded silicone rubber keymats with the low-profile interconnectivity of flexible silver or FPC circuits. We also fabricate zero-travel capacitive ITO (Indium Tin Oxide) glass/PET touch panels for ultra-sterile clinical environments.
