Manufactured under strict ISO quality standards in our 10,000㎡ facility, tailored for industrial automation, clinical medical tech, and commercial machinery across Catalonia.
In the heart of Catalonia's industrial manufacturing network—spanning from the high-tech automation corridors of El Vallès Occidental (Terrassa, Sabadell) and the logistics and manufacturing nodes of Baix Llobregat to the biomedical incubators of Barcelona Activa—engineering requirements for Human-Machine Interfaces (HMIs) demand far more than basic electrical continuity. System architects and embedded hardware engineers operate under tight environmental directives (CE, RoHS, REACH) and severe duty-cycle constraints.
As premier manufacturers and international exporters of custom flexible membrane switches, AXRU Electronics delivers an end-to-end engineering bridge between Chinese industrial scale and Barcelona's precision engineering criteria. A standard flexible membrane switch is a complex multi-layer composite system where mechanical actuation force, polymer dielectric strength, conductive trace chemistry, and adhesive shear stability must be mathematically orchestrated. The core stack-up involves an Autotex® or Melinex® textured polyester graphic overlay, sub-surface screen-printed using solvent-resistant acrylic or UV-curable inks. This protects legends against heavy industrial degreasers, sanitizing alcohols, and saline coastal air typical of Mediterranean manufacturing plants.
Directly below the graphic fascia, a custom-engineered spacer layer holds precision-formed stainless steel metal domes (typically four-leg, round, or oblong configurations varying from 6mm to 20mm with actuation forces calibrated between 180g and 450g). These domes interface with screen-printed silver ink traces on thermal-stabilized PET films or etched copper Polyimide Flexible Printed Circuits (FPC). For mission-critical Spanish applications—such as hemodialysis machinery, commercial packaging thermoformers, and automotive body shop diagnostics—our micro-gap circuit layouts prevent trace migration and carbon bridging even when exposed to fluctuating coastal humidity and aggressive cyclic thermal shocks.

From the pharmaceutical epicenters of Sant Cugat to the heavy automotive corridors of Martorell, custom HMI configurations address distinct mechanical and environmental stressors.
Barcelona's medical technology hub demands biomedical front panels with micro-textured, antimicrobial polyester surfaces resistant to hospital-grade disinfectants like Isopropanol, Sodium Hypochlorite, and Sporicides. Hermetically sealed edge gaskets ensure total fluid ingress prevention (IP67) for surgical monitors and infusion controllers.
Serving Tier-1 and Tier-2 automotive innovators across the Martorell and Zona Franca industrial parks. We supply high-temp Polyimide (FPC) switches, tactile mirror dials, and In-Mold Decoration (IMD) panels engineered to withstand automotive cabin vibration, UV radiation, and rapid thermal cycling (-40°C to +85°C).
For machine tool builders in Sabadell and Terrassa, our heavy-duty silicone rubber keypads and embossed tactile membrane arrays provide crisp snap ratios (40%-60%) that allow operators wearing thick work gloves to confidently confirm input triggering amidst high acoustic and vibrational shopfloor noise.
How the green transition, Industry 4.0 digitisation, and smart packaging are reshaping interface procurement across southern Europe.
As Catalan logistics centers and cobot manufacturers upgrade to tactile feedback systems, thin-film flexible pressure sensors (as shown in our mirror array series) are replacing bulky mechanical load cells. These sensors are integrated directly into gripping arms, monitoring uniform surface force in real time via sub-millimeter profiles.
Medical electronics OEMs in Sant Cugat are moving toward hybrid user interfaces. They combine solid-state capacitive touch zones for menu scrubbing with physical metal-dome switches for safety-critical emergency stops. This avoids touch-screen latency while maintaining a clean, IP66-sealed continuous perimeter.
Spanish industrial buyers actively seek supply chain partners compliant with the EU Ecodesign regulation. AXRU supports these criteria with halogen-free conductive carbon inks, lead-free SMD soldering, and recyclable PET and Lexan™ formulations that streamline product end-of-life recycling programs.
Eliminating third-party subcontracting risks. Precision screen printing, computerized SMD pick-and-place, laser cutting, and environmental testing occur under one audited roof in Dongguan, China.
Every membrane trace is tested for open circuits, short circuits, insulation breakdown, and micro-ohm loop impedance before packaging.
High-speed pneumatic actuators cycle tactile dome arrays up to 5,000,000 continuous hits to verify snap stability and contact rebound time.
Plots actuation force, return force, and travel distance curves to ensure a consistent tactile feel across every batch.
Subjecting prototypes to extreme thermal swings (-40°C to +105°C) and 95% RH to verify adhesive boundary seals against delamination.
Validates surface ink durability against ethanol, MEK, and continuous abrasive cycles under calibrated weights.
Verifies optical window clarity and color stability under continuous UV radiation, preventing embrittlement in Mediterranean outdoor enclosures.
