Explore our export-grade custom silicone rubber keypads, tactile membrane switches, and integrated circuit assemblies. Custom-molded for extreme thermal tolerance, tactile consistency, IP67/IP68 sealing, and laser-etched illumination for industrial equipment manufacturers across the Comunitat Valenciana.
As a primary human-machine interface (HMI) component, custom silicone rubber button keypads provide tactile feedback, sealing integrity, and ergonomic satisfaction across diverse operating environments. Manufactured from high-consistency silicone rubber (HCR) or liquid silicone rubber (LSR), these keymats utilize compression molding or liquid injection processes to achieve precise geometric profiles, tailored actuation forces, and durable mechanical resilience.
For original equipment manufacturers (OEMs) and design engineers serving Valencia’s industrial corridors, choosing the correct keypad architecture requires analyzing key force-displacement curves, contact surface metallization, atmospheric resistance, and backlighting mechanics.
Silicone keypads are compounded across a hardness range from 30 Shore A to 80 Shore A. Lower durometer formulations (30-40 Shore A) provide soft, quiet actuations suitable for medical devices, whereas higher durometer levels (60-70 Shore A) deliver firm, crisp tactile clicks required in automotive cockpits and heavy machinery controls.
The mechanical feedback of a silicone button is governed by its web design (angle, thickness, and height). The snap ratio—calculated as (Actuation Force - Return Force) / Actuation Force × 100%—typically targets 40% to 65%. A higher snap ratio yields a distinct tactile "click," preventing accidental keystrokes in high-vibration automotive or industrial environments.
To bridge underlying printed circuit boards (PCBs) or flexible printed circuits (FPCs), silicone keymats integrate conductive carbon pills (resistance < 100 Ω), low-resistance gold-plated pills (< 1 Ω), or matrix-printed conductive inks. Alternatively, silicone keymats can actuate tactile metal domes for ultra-crisp snapping profiles.
For illuminated night-vision controls, keypads are molded from translucent silicone rubber, sprayed with an opaque color coating (or multi-layer coatings), and laser-etched to remove precise paint layers. Combined with custom light guide films (LGF) or LED diffusion channels, our laser-etched silicone keypads deliver uniform illumination without hot-spots or optical light bleed, passing ISO 16750 night-design standards.
Valencia represents one of Spain's most dynamic industrial ecosystems, characterized by high-tech manufacturing clusters, automotive engineering complexes, marine logistics hubs, and medical technology incubators. As a specialized silicone button keypad manufacturer, our factory supplies custom-built user interfaces engineered to address the distinct mechanical, environmental, and aesthetic requirements of Valencian enterprises.
Centering around the Juan Carlos I Industrial Park in Almussafes, Valencia’s automotive cluster demands zero-defect HMI components conforming to IATF 16949 standards. Our silicone button keypads are deployed in vehicle steering wheel controls, HVAC system panels, commercial EV charging stations, and cabin lighting modules. Features include PU/UV protective coatings, laser-etched backlit icons, and high thermal resistance (-40°C to +120°C) capable of enduring intense Mediterranean solar radiation and cockpit heat cycles.
As one of the Mediterranean's busiest container ports, Valencia’s maritime logistics, crane manufacturing, and naval electronics operations require interface control pads that resist salt spray corrosion, constant UV exposure, and heavy mechanical impacts. We manufacture IP68 perimeter-sealed silicone keymats featuring integrated liquid-proof rims, anti-microbial coatings, and high-tear silicone formulations that prevent sea-water intrusion into vessel bridge controls and quay-side container handling crane consoles.
Medical equipment innovators operating near the Parc Científic de la Universitat de València and health-tech centers require seamless, easy-to-clean interfaces. Our biocompatible silicone keypads are molded from USP Class VI and ISO 10993 compliant liquid silicone rubber. Designed to withstand repeated cleaning with harsh hospital disinfectants (isopropyl alcohol, bleach, iodine solution), these seamless keymats are integrated into patient monitors, diagnostic devices, and surgical control units.
Valencia’s famed agricultural and food-processing automation sector relies on automated sorting machines, citrus packing conveyors, and irrigation controllers. These machines operate under high humidity, dust, and washdown protocols. Our silicone rubber keypads feature molded seal bezels that meet IP69K standards, guarding internal electronics against direct high-pressure hose-downs, juice acids, and ambient agricultural dust.

Manufacturing for the European Union market requires strict adherence to environmental directives, chemical safety regulations, and quality standardizations. When sourcing silicone keypads for installation or export within the EU, engineering teams must ensure full traceability and material testing certification.
- EU RoHS 3 Compliance (Directive 2015/863): All silicone polymers, pigment colorants, conductive carbon pills, and adhesive backings supplied to Valencia are certified free of heavy metals (Lead, Mercury, Cadmium, Hexavalent Chromium) and restricted phthalates (DEHP, BBP, DBP, DIBP).
- REACH Regulation & SVHC List: Materials are regularly audited to guarantee that none of the Substances of Very High Concern (SVHC) published by the European Chemicals Agency (ECHA) exceed 0.1% weight by weight (w/w).
