Custom Polycarbonate Overlays & Membrane Interface Matrix
Precision-printed graphic overlays, IP67 waterproof membrane switches, tactile metal dome panels, and integrated silicone elastomer keypads ready for direct shipment to Mexico City, Estado de México, and Querétaro manufacturing hubs.
Why Polycarbonate (PC) Overlays Dominate Mexico's Industrial & Medical OEM Hubs
In-depth mechanical, optical, and environmental assessment of Polycarbonate (Lexan™ 8010, HP92S, 8B35) membrane panels deployed across the Valley of Mexico.
High-Altitude Barometric Compensation
At Mexico City's mean elevation of 2,240 meters (7,350 feet), atmospheric pressure is roughly 22% lower than sea level (~77 kPa vs 101.3 kPa). Standard sealed membrane switches can suffer from "pillow bulging" or premature dome actuation. AXRU designs custom internal micro-venting channels fitted with semi-permeable ePTFE hydrophobic membrane vents to balance internal and external pressures while maintaining an uncompromising IP67 ingress rating.
Intense Altiplano UV & Heat Resistance
The elevated UV index of the central Mexican plateau causes rapid polymer embrittlement and yellowing in substandard films. We formulate our graphic overlays using UV-stabilized Lexan™ polycarbonate or apply anti-glare, anti-UV hardcoats (rated up to 3H pencil hardness). Our in-house accelerated weathering chambers subjected to 500+ hours of continuous UV-A and UV-B exposure ensure that legend printing and color saturation stay crisp in outdoor ticket dispensers, EV chargers, and fuel kiosks.
Chemical & Hospital Disinfectant Barrier
Supplying medical equipment manufacturers clustered around Mexico City (Tlalnepantla and Naucalpan), our Polycarbonate and textured hybrid overlays resist aggressive cleaning agents like Isopropyl Alcohol (70%+), Sodium Hypochlorite (Bleach), Hydrogen Peroxide, and chlorhexidine gluconate. Sub-surface silk-screen printing ensures ink layers are hermetically shielded from mechanical abrasion and chemical wipe-downs.

Serving the Greater Mexico City (ZMVM) OEM & EMS Corridor
From Tier-1 automotive systems to sophisticated biomedical instruments, AXRU's engineering team provides customized Human-Machine Interfaces tailored to regional supply chain requirements.
Automotive & Commercial Vehicle Electronics
The automotive belt stretching from Vallejo and Naucalpan to the Toluca-Lerma industrial basin houses leading Tier-1 and Tier-2 manufacturers. AXRU manufactures custom automotive gauge faces, anti-glare dashboard overlays, and HVAC climate control membrane panels. Our products meet rigorous USMCA / T-MEC compliant raw material traceability standards, offering low-resistance silver circuits, integrated light guides, and dead-front automotive warning icons that remain invisible until backlit.
Medical Devices & Diagnostic Instrumentation
With Mexico City serving as the primary healthcare and medical device distribution epicenter in Latin America, our membrane switches power patient monitors, infusion pumps, and lab centrifuges. Designed to satisfy stringent hospital sanitation routines, our antimicrobial Polycarbonate overlays prevent bacterial propagation, while tactile metal domes calibrated between 250g and 450g actuation force provide unambiguous feedback through clinical surgical gloves.
Industrial Automation & CNC Machine Panels
In the manufacturing zones of Tlalnepantla, Cuautitlán Izcalli, and Iztapalapa, factory automation requires rugged front panels capable of repelling machine oil, coolants, and heavy vibration. We engineer robust multi-layer assemblies incorporating 3M 300LSE adhesive for textured powder-coated steel enclosures, alongside built-in ESD shielding layers (aluminum foil or carbon grid) that discharge static electricity up to 15kV.
Commercial Equipment, Vending & Smart Fuel Dispensers
Urban infrastructure across Mexico City demands vandal-resistant, weatherproof outdoor keypad solutions. AXRU manufactures ruggedized stainless-steel hybrid membranes and heavy-gauge embossed Polycarbonate interfaces for gas station fuel dispensers, parking fee terminals, mass-transit ticket dispensers (Metrobús / Metro CDMX), and commercial kitchen ovens requiring temperature endurance up to 105°C.
Nearshoring Dynamics: Why Mexican Maquiladoras Source from AXRU China
Balancing rapid rapid-prototyping, high-precision tooling economics, and dependable cross-Pacific air & ocean logistics.
Cost-Efficiency & Tooling Agility
While assembly lines relocate closer to the US market via Mexican nearshoring, local tooling and high-precision silk-screen stencil facilities in CDMX remain capital-intensive. By partnering with AXRU, buyers leverage Dongguan’s complete industrial supply chain, reducing tooling setup fees by up to 60% and receiving mass production batches with low 100-piece MOQs.
Expedited Logistics to CDMX (MEX / NLU)
We maintain established logistics partnerships delivering directly into Mexico City via air cargo through Benito Juárez International Airport (MEX) and Felipe Ángeles International Airport (NLU) within 4 to 7 business days. For high-volume production runs, consolidated ocean containers arrive via the Port of Manzanillo or Lázaro Cárdenas with bonded customs clearance.
Strict Tariff & NOM Compliance
Our export documentation precisely itemizes Harmonized System (HS) classifications (such as HS Code 8537.10 for electrical control panels and membrane switches). We provide full Certificates of Origin (COO), RoHS / REACH declarations, and technical datasheets allowing seamless customs clearance for companies operating under Mexico's IMMEX program.
