Explore our precision-manufactured conductive silicone interfaces, ruggedized membrane keyboards, and advanced FPC circuitry engineered for mission-critical deployments across Eastern Ontario.
Evaluating actuation force profiles, conductive pill composition, and environmental resistance mechanisms for high-reliability hardware.
Conductive silicone rubber keypads rely on vulcanized contact elements that short circuit traces on mating PCBs or FPCs upon depression. Our Langfang facility molds ultra-low-resistance carbon conductive pills (contact resistance < 50Ω) formulated with micron-grade graphite dispersoids.
For high-frequency telecommunications or low-voltage digital signal routing where contact drops must not exceed millivolts, we incorporate specialized gold-plated brass contacts, nickel-coated pills, or integrate stainless steel tactile domes under the silicone webbing for simultaneous crisp tactile snap and instant electrical closure.
The ergonomic feel of an elastomeric keyboard is governed by its force-displacement curve: the ratio between peak actuation force (F1) and return force (F2). Known as the Snap Ratio [calculated as (F1 - F2) / F1 × 100%], this metric dictates whether an operator perceives a mushy travel or an authoritative mechanical confirmation.
Our tooling design team tunes the silicone durometer (30 to 70 Shore A) alongside the angle, thickness, and radius of the elastomeric collapsible webbing wall. This ensures actuation longevity surpassing 5,000,000 cycles without fatigue cracking or contact bounce degradation.
Ottawa hardware often faces demanding outdoor deployment conditions, industrial airborne contaminants, or aggressive hospital disinfection regimes. We mold integrated peripheral gasket sealing lips directly into the keypad geometry, achieving true IP67 and IP68 enclosure isolation without secondary O-rings.
To resist mechanical abrasion and solvent swelling from isopropanol, ethanol, or synthetic oils, the outer key legends receive dual-stage post-curing treatments: polyurethane spray coatings, matte UV fluorosilicone barriers, or crystal-clear epoxy resin doming for scratch-proof durability.

Tailoring human-machine interface components to meet the engineering, compliance, and thermal requirements of the National Capital Region's leading high-tech clusters.
In Kanata North—Canada's largest technology park—telecom equipment manufacturers design carrier-grade networking hardware, optical switches, and satellite uplink terminals. These systems demand sub-rack maintenance interfaces and front-panel diagnostic keypads that survive decades of continuous operation.
Our conductive rubber keypads provide reliable tactile response, laser-etched backlit graphics using high-transmission optical silicone, and integrated FPC tails that mate cleanly into compact 1U/2U server chassis.
Ottawa serves as the procurement and systems engineering headquarters for Canada's Department of National Defence (DND). Tactical vehicular computers, soldier-worn comms gear, and field-deployable command terminals require keypads operating flawlessly across Arctic conditions (-40°C) without becoming brittle or stiff.
We formulate low-temperature elastomeric compounds with matte anti-reflective finishes, night-vision goggle (NVG) compatible backlighting, and internal EMI/RFI shielding foils to satisfy MIL-STD-810G vibration and EMC requirements.
With world-renowned institutions like the Ottawa Hospital Research Institute and University of Ottawa Heart Institute, the capital region hosts innovative biomedical and diagnostic instrumentation OEMs. Medical control surfaces require seamless, crevice-free geometries that can be sanitized hundreds of times daily.
Our molded silicone keypads integrate continuous wraparound sealing aprons, antimicrobial additives, and chemical-resistant PU topcoats that resist degradation from aggressive quaternary ammonium and sodium hypochlorite disinfectants.
Strategic supply chain evolution: how environmental directives, Smart City IoT, and advanced tactile feedback shape HMI component specifications.
The City of Ottawa's Climate Change Master Plan has accelerated investments in zero-emission transit, municipal electric vehicle fleet charging networks, and municipal IoT monitoring nodes. These publicly exposed interfaces face freezing rain, blowing snow, UV degradation, and vandalism.
Local design teams increasingly specify dual-action keypads combining conductive elastomeric bodies with polycarbonate caps, preventing keyway moisture freezing while retaining positive actuation feel under thick winter work gloves.
Canadian procurement authorities and Ottawa-based exporters targeting European and American markets are enforcing strict compliance with Health Canada chemical directives, RoHS 3, and REACH SVHC declarations. Non-compliant curing agents (such as aromatic phthalates or halogenated flame retardants) are prohibited.
TAVO guarantees 100% full-declaration raw materials. Every silicone batch is cured with high-purity platinum catalysts, ensuring zero toxic outgassing and complete biocompatibility certification for sensitive medical and aerospace installations.
Engineers in Kanata North are pioneering hybrid HMI architectures: combining sleek capacitive slider panels with tactile conductive rubber pushbuttons for emergency abort, power cycling, and primary numeric entry. This eliminates false-positives caused by water droplets on touchscreens.
We provide full structural integration: our factories laminate molded silicone rubber keypads directly over rigid FR4 PCBs, flexible printed circuits (FPCs), or back-illuminated light guide film (LGF) arrays, shipping one fully tested turnkey assembly.
Founded in 1990, TAVO operates 2,219 square meters of verified cleanroom manufacturing floorspace, housing dedicated mold tooling, screen printing, SMT assembly, and comprehensive reliability testing laboratories.
Unlike trading intermediaries, our Langfang headquarters maintains an internal precision machine shop featuring 60 CNC mold-making machines, linear wire cutting units, and EDM spark machines. We machine high-precision multi-cavity compression molds directly from 3D CAD models within 5 to 7 working days.
We balance production between our primary manufacturing plant in the Robot Industry Port of Xianghe (Hebei) and our southern manufacturing center in Huizhou (Guangdong). This dual-facility synergy ensures uninterrupted supply chains, risk mitigation, and flexible prototype-to-mass-volume scaling.
A sustained long-term technical cooperation agreement with a premier German membrane switch specialist governs our process specifications, cleanroom hygiene, and quality management protocols. Our 111+ full-time employees include 30+ senior process technicians with over 15 years of practical manufacturing experience.
Operating under certified ISO 9001:2015 frameworks, our factory has passed rigorous on-site verification audits conducted by Intertek. Every keypad batch undergoes 100% automated electrical continuity testing, dimensional keyway CMM verification, and retention pull tests prior to export dispatch.
