Manufactured to MIL-STD and industrial ingress specifications. Fully customizable substrate materials, surface textures, switch force profiles, and circuit routing.
In human-machine interfaces (HMI), the graphic overlay and front panel are no longer merely decorative fascias—they are mission-critical electromechanical boundaries responsible for device longevity, signal integrity, and user experience.
Global original equipment manufacturers (OEMs) in North America and Western Europe are systematically shifting toward integrated single-source sub-assemblies to eliminate multi-tier supply chain risks and yield loss.
The boundary between purely mechanical tactile switches and advanced capacitive touch surfaces has dissolved, yielding hybrid architectures optimized for challenging industrial environments.
Choosing between Polycarbonate (PC), Biaxially Oriented Polyethylene Terephthalate (PET), and PMMA glass determines real-world mechanical survival under harsh operating stresses.

Located in the global hardware epicentre of Dongguan, China, Dongguan AXRU Electronics Co., Ltd. operates a modern 10,000㎡ industrial complex with 121 specialized engineers and operators. Every stage—from artwork CAD translation and precision silkscreening to FPC bonding, laser die-cutting, and computerized electrical validation—is executed internally.
Unlike trading entities or outsourced assemblers, our unified production ensures complete traceability, confidentiality for proprietary designs, and rigorous adherence to IPC-A-610 electrical assembly standards.
Every membrane switch panel, graphic overlay, and elastomer keypad undergoes exhaustive validation on calibrated scientific test equipment before leaving our docks.
Our computerized key force testers plot the exact force curves of stainless steel domes, measuring actuation gram force, rebound click ratio, and travel distance to maintain consistent fingertip sensation across batch runs.
Accelerated life testing in programmable temperature and relative humidity chambers (-40°C to +120°C, 95% RH) ensures adhesive perimeter barriers remain watertight and bubble-free under harsh tropical or arctic deployment.
Using linear RCA wear testers and cross-hatch adhesion rub tests with pure isopropyl alcohol, ethanol, and acetone, we ensure that reverse-printed inks and matte top surface textures never delaminate or fade over decades of use.
Everything you need to know about engineering drawings, layer stacks, prototyping timelines, and electrical compliance.
For custom printed graphic overlays and membrane switch assemblies, our standard MOQ begins at just 100 pieces. We offer dedicated engineering pilot runs for prototyping, clinical trial devices, and low-volume high-value industrial systems.
For graphic overlays, provide vector files in Adobe Illustrator (.AI), CorelDraw (.CDR), or Vector PDF with specific Pantone (PMS) or RAL color codes. For circuits, stack-ups, and die-lines, provide AutoCAD (.DWG, .DXF) or Gerber files indicating tail routing and connector pinouts.
We deploy continuous perimeter gasket seals using genuine pressure-sensitive acrylic adhesives (such as 3M 467MP, 468MP, or 3M 200MP series). Combined with internal breathers routed into the electronic enclosure rather than the exterior, ingress of water, oil, and dust is prevented.
Engineering sample prototypes are delivered within 5 to 7 working days upon film artwork sign-off. Mass volume production generally ships within 12 to 18 working days, supported by express international air freight (DHL, FedEx, UPS) and door-to-door sea shipping.
Yes. We integrate ultra-thin surface-mount SMD LEDs (0603, 0805, 1206 footprints) directly into the circuit layer. For full-surface uniform illumination, we combine micro-dot Light Guide Film (LGF) or fiber-optic layers driven by minimal power while avoiding hotspot glare.
We integrate full-coverage perimeter aluminum foil, conductive grid carbon printing, or copper grounding shields within the layer stack. These shields absorb ESD strikes of up to 15kV to 25kV and channel the energy safely to the chassis ground, protecting sensitive microcontrollers.
