Precision Aerospace-Grade HMI Engineering, Biocompatible Substrates, and Rapid-Turnaround Custom Membrane Assemblies for Occitanie's High-Reliability Sectors.
Direct-from-factory high-performance human-machine interfaces, thin-film force resistors, and tactile switches engineered to comply with ISO 9001, RoHS, and CE operational standards.
As a global frontrunner in custom Human-Machine Interface (HMI) manufacturing, Dongguan AXRU Electronics Co., Ltd. provides advanced OEM/ODM manufacturing of Polyethylene Terephthalate (PET) graphic overlays and multi-layered membrane switches directly serving Toulouse's specialized industrial ecosystem. Located in the heart of Europe’s premier aeronautics, aerospace, and high-tech defense corridor (Occitanie), engineers and procurement officers in Toulouse require material solutions that transcend generic commercial standards. Designing control fascias for aerospace ground support instrumentation, avionics test benches, satellite integration rooms, and high-sterility medical bioprocessing equipment demands unmatched mechanical dimensional stability, comprehensive chemical resistance, and predictable tactile response.
Unlike ordinary Polycarbonate (PC) materials that can suffer micro-fracturing under exposure to harsh aerospace cleaning solvents, hydraulic fluids, and constant UV exposure, our biaxially-oriented optical PET substrates (Autotex®, Melinex®) deliver a flexural endurance cycle exceeding five million switch actuations without elongation or stress cracking. Engineered through sub-surface screen and high-definition digital reverse printing, our overlays encapsulate all typography, brand heraldry, dead-front status indicators, and display filtration windows beneath an impenetrable barrier layer. This ensures absolute resistance against isopropyl clean-downs, skydrol exposure, abrasive grit, and broad operational thermal shifts ranging from -40°C to +85°C.
A fundamental requirement for engineering teams in the Toulouse region is balancing flex life with cosmetic longevity. When an overlay features embossed key profiles—such as rim embossing, pillow embossing, or bespoke dome-profile tactile reliefs—internal tensile stress becomes a point of potential mechanical fatigue. PET possesses superior molecular tensile modulus and chemical inertness compared to polycarbonates or vinyls. Polycarbonate, while exhibiting outstanding impact resistance for heavy structural panels, exhibits vulnerability when subjected to localized cyclic flexing; it tends to experience embrittlement over time, leading to micro-fissuring at the embossing hinges.
Our specialized fabrication facility deploys thermally stabilized, pre-shrunk polyester films. By relieving the residual internal casting stress of the PET roll stock prior to multi-pass silk-screen registration, we eliminate positional registration drift down to tolerances within ±0.05 mm across successive layer lamination. This thermal treatment is critical when integrating transparent display cutouts for avionics OLEDs, capacitive slider apertures, and precision-routed LED backlighting matrices. Whether specifying anti-glare, fine-matte, selective-gloss, or antimicrobial surface treatments, our PET overlays provide consistent optical clarity and rugged structural integrity throughout the equipment's entire life cycle.
| Performance Characteristic | Premium Biaxially-Oriented PET | Standard Polycarbonate (PC) | Silicone Elastomer Fascia |

| Aviation Solvent & MEK Resistance | Excellent; unaffected by Skydrol, fuels & alcohols | Moderate to Poor; swells & crazes on contact | Good; requires specialized fluorosilicone barrier |
| Optical Window Clarity | High transparency with anti-scratch coating | Optically clear, soft surface scratches easily | Translucent only (requires bonded plastic lens) |
| Tactile Dome Feedback Retention | Crisp tactile snap transfer; snap ratio > 45% | Dampened tactile feedback over time | Soft ergonomic press, lower snap definition |

Toulouse is recognized globally as the capital of European aeronautics, but its manufacturing fabric is remarkably diverse, spanning space telemetry, embedded rail transit controls, agricultural biotechnology, and advanced medical diagnostics. AXRU’s custom OEM/ODM graphic overlays and membrane switch interfaces serve several distinct regional sectors:
1. Aerospace GSE & Avionics Maintenance: Toulouse-Blagnac and surrounding aerospace complexes utilize Ground Support Equipment (GSE), hydraulic pressure testing rigs, and portable avionics field diagnostic computers that must operate under severe weather variations, high vibration, and accidental fuel/chemical spills. Our IP67 perimeter-sealed PET overlays with integrated EMI/RFI shielding grids protect delicate inner microcircuits from stray radar and high-frequency RF interference.
2. Satellite Telemetry & Cleanroom Consoles: In Toulouse’s Space Valley (Labège, Montaudran), precision assembly and telemetry tracking bays mandate low-outgassing human-interface panels that prevent volatile organic contamination inside controlled satellite testing chambers. AXRU customizes multi-layer overlays using low-outgassing 3M aerospace-certified acrylic adhesives and conductive silver traces with vulcanized encapsulation.
3. In-Vitro Diagnostics & MedTech Devices: The Occitanie health-tech corridor focuses heavily on laboratory automation, fluidics analyzers, and surgical control peripherals. Our polyester graphic overlays incorporate anti-microbial coatings and sealed flush boundaries, allowing hospital personnel to sanitize equipment using aggressive quaternary disinfectants and hypochlorite wipes without legend fading or moisture ingress.
The rapid modernization of France’s industrial infrastructure under the "France 2030" initiative is accelerating transitions in human-machine interface architectures across Toulouse:
Capacitive & Membrane Sensor Hybridization: Traditional electro-mechanical switches are increasingly transitioning to hybrid user interfaces. Designers in Toulouse are embedding capacitive proximity sensing electrodes directly behind decorated PET surfaces, combining dead-front lighting (icons remain completely invisible until illuminated from behind) with tactile confirmation via localized piezoceramic or high-force snap metal domes.
Integration of Flexible Thin-Film Force Resistors (FSR): Modern medical rehabilitation and smart aerospace pilot training interfaces require proportional tactile feedback rather than binary on/off switching. By printing multi-point FSR matrices directly onto the internal PET circuit layer, our overlays now provide real-time pressure-sensitive control for variable-speed actuators and robotic manipulators.
Direct oversight across screen printing, precision die-cutting, cleanroom lamination, and automated electrical QA ensures that every project meets exacting European procurement standards.
Our 121-person manufacturing plant operates under certified ISO 9001 and ISO 13485 protocols, inspected on-site by Intertek. No outsourced processes—100% accountable control from raw polyester cutting to packaging.
Equipped with automated force-displacement testers, key cycle testers (validated up to 5M strikes), tensile adhesive peel benches, programmable temperature-humidity chambers, and UV weathering instruments.
Our senior membrane switch engineers work directly with your Toulouse engineering team. We conduct thorough Design for Manufacturability (DFM) reviews, reviewing tail pitches, dome sizes, venting channels, and gasket clearances prior to tooling.
