Vienna serves as the innovation center of Central Europe, bridging Austrian high-precision manufacturing with advanced biomedical and transit networks. Discover how our custom silicone rubber keypads and membrane switch assemblies solve operational challenges across prominent regional sectors.
Centered in the Vienna BioCenter and clinical engineering clusters throughout Vienna-Donaustadt, medical devices demand sterile, continuous-duty HMI interfaces. Our silicone keypads feature seamless monoblock construction that prevents fluid ingress, bio-burden accumulation, and chemical degradation from hospital-grade disinfectants.
Industrial machinery builders in the Greater Vienna-Schwechat industrial belt deploy our high-snap tactile keypads inside CNC interfaces, handheld teach pendants, and variable frequency drive (VFD) controls where heavy mechanical vibration and oil mist are omnipresent.
Austria’s rail infrastructure (ÖBB hubs) and rapid EV charging networks in urban Vienna require interfaces that withstand alpine freeze-thaw cycles, aggressive UV radiation, and public vandalism. We produce backlit silicone keyboards engineered with vulcanized liquid silicone rubber (LSR).
Evaluate technical parameters to balance mechanical snap ratios, environmental sealing, and lifecycle costs prior to tooling fabrication.

Driven by Austrian federal sustainability mandates, Industry 4.0 automation, and EU Medical Device Regulations (MDR), human-machine interfaces are undergoing technological shifts.
Austrian industrial designers increasingly reject flat membrane overlays in favor of hybrid designs that combine 3D molded silicone rubber keymats with underlying flexible printed circuits (FPC). This architecture provides three-dimensional ergonomic finger location, superior tactile response, and the high circuit density required for space-constrained electronics.
With Austrian supply chains strictly auditing ESG criteria under the EU Corporate Sustainability Due Diligence Directive, our factory provides platinum-cured silicone elastomers that eliminate post-curing peroxide by-products, meet RoHS 3 and REACH SVHC regulations, and utilize recyclable tooling fixtures.
Demanded by high-end Vienna medical instrumentation, "dead-front" legends remain completely invisible until backlit by internal LEDs. By applying multi-layer spray coatings (translucent base, opaque barrier, textured protective clear coat) and computer-controlled laser ablation, we achieve crisp legibility with zero light bleed.
Dongguan Ravo Electronics Co., Ltd. operates a 12,000 m² state-of-the-art facility in Fenggang Town, Dongguan. Since 2003, our multidisciplinary engineering team has provided Western European buyers with an integrated production chain: internal mold tool fabrication, compression rubber molding, precision silkscreen and digital printing, laser etching, automated SMT component placement, and 100% electrical continuity testing.

Rapid pilot-run tooling and CNC silicone prototyping allow Vienna R&D teams to validate ergonomics and snap ratios without full production mold capital.
Strict optical key alignment, contact resistance verification (<100Ω carbon pill, <1Ω metal pill), and life-cycle test documentation provided with every shipment.
Key technical, compliance, and logistics clarifications for sourcing custom silicone rubber keypads and membrane switches from China into the Vienna metropolitan region.
We regularly ship to Vienna International Airport (Schwechat / VIE) via expedited air freight (DHL, FedEx, UPS) with an average transit time of 4 to 6 business days. For high-volume sea/rail freight, consignments transit via Hamburg or Koper direct to Vienna terminals within 24 to 28 days. We support DAP and DDP Incoterms, streamlining Austrian customs clearance with complete HS code classification and EUR.1 documentation.
Yes. Every raw material batch—including silicone gum bases, vulcanizing agents, color masterbatches, conductive carbon pills, and printed conductive inks—is certified RoHS 3 (Directive 2015/863/EU) and REACH (EC 1907/2006) compliant. Complete third-party SGS/TÜV test reports and material declaration sheets are furnished alongside prototype inspection reports.
Tactility is determined by the keypad's silicone webbing geometry: the angle, thickness, and length of the elastomeric wall. Our engineers calculate the exact snap ratio (typically between 40% and 60%) to deliver a tactile click without operator fatigue. For higher tactile feedback, we integrate stainless-steel tactile metal domes beneath the silicone keycaps.
We offer three protective coating technologies: Smooth Matte Polyurethane (PU) spray coating for general industrial abrasion resistance; Hard-Coated UV Curable Clear Lacquer for heavy cycle wear; and vapor-deposited Parylene coating for medical diagnostic instruments requiring continuous wipe-down exposure to alcohol, bleach, and quaternary disinfectant solutions.
Yes. We specialize in primer-treated pressure-sensitive adhesives (utilizing 3M 9448A, 3M 467MP, or 3M 300LSE for low surface energy plastics) as well as overmolding silicone rubber directly onto rigid plastic (polycarbonate/PBT) or aluminum frames. This creates an IP68 hermetic barrier preventing fluid ingress between the keymat and housing.
We recommend submitting a 3D CAD model (.STEP, .IGES) defining key travel, draft angles, and webbing thickness, along with a 2D engineering drawing (.PDF, .DWG) specifying actuation force, Pantone/RAL color codes, printing legends, and electrical contact resistance tolerances. If electrical layers are integrated, provide Gerber circuit files.
