Manufactured in our ISO 9001:2015 certified Dongguan facility with SGS-verified process traceability, delivering ingress protection up to IP67 and 1,000,000+ switching cycles.
The Greater Poland (Wielkopolska) industrial belt—anchored by Poznań, Tarnowo Podgórne, Komorniki, and Swarzędz—has emerged as one of Central Europe's most sophisticated manufacturing corridors. With heavy concentrations of Tier-1 and Tier-2 automotive electronics, cutting-edge automated warehouse systems, food processing packaging lines, and medical diagnostics equipment, device designers require Human-Machine Interfaces (HMIs) that endure severe chemical, mechanical, and climatic stressors.
Dongguan Cevra Electronic Technology Co., Ltd. serves Poznań-based industrial designers and procurement teams by delivering direct-from-factory keyboard overlays and integrated membrane switches. By eliminating intermediary trading costs and integrating Class 1,000 cleanroom printing, CNC digital cutting, and automated dome placement, we meet stringent CE, RoHS, and REACH requirements with rapid rapid-turn delivery directly to Poznań-Ławica cargo or via the Małaszewice rail terminal corridor.
From factory floor automation in Tarnowo Podgórne to clinical diagnostics in Poznań research laboratories, explore how our graphic overlays and dome arrays are structurally specified.
Poznań is a premier European intermodal hub. Handheld barcode terminals, AGVs (Automated Guided Vehicles), and distribution sorters engineered in the region operate 24/7. We construct anti-glare, textured Autotex® polyester keyboard overlays that withstand drop shocks, constant abrasion, and wide temperature swings (-30°C to +75°C) without delaminating or suffering tactile snap degradation.
Wielkopolska is an agricultural and food packaging stronghold. Equipment control panels require strict IP66/IP67 washdown protection against pressurized hot water and harsh alkaline sterilization agents. Cevra applies anti-microbial coatings, closed-cell silicone perimeter seals, and chemically inert PET materials that resist fat, sanitizers, and alcohol wipes without yellowing or micro-cracking.
For medical devices produced around Poznań’s university clinical centers, flat surface cleanliness and clear optical display windows are non-negotiable. Our cleanroom-manufactured polycarbonate and PET overlays incorporate dead-front printed indicator zones, anti-glare transparent windows with light transmission >92%, and responsive non-tactile capacitive or soft-snap tactile feedback designed for operator glove usage.
With Poland’s rapid transformation toward green residential heating and PV inverter manufacturing, Poznań OEMs require external control keypads resistant to prolonged UV radiation (IEC 60068-2-5), thermal cycling, and moisture ingress. We formulate UV-stabilized exterior-grade XE films bonded with moisture-resistant acrylic adhesives to prevent moisture creeping into circuit channels.
Positioned near major commercial vehicle and specialty truck assembly corridors, our automotive-grade overlays integrate SUS301 high-retention snap domes. Delivering consistent actuation forces (from 220g to 450g) and crisp tactile feedback even when operated by drivers wearing protective work gloves, our switches ensure zero erratic signal bounce under intense mechanical vibration.
Precision tooling and metal-forming workshops across Poznań depend on heavy-duty control panels that endure constant contact with cutting emulsions, coolants, and lubricating greases. Utilizing high-chemical-tolerance Autotex Steel or textured polycarbonate with reinforced spacer channels, our assemblies prevent fluid ingress and guarantee uninterrupted plant performance.
How the evolution from passive mechanical button plates to smart, hybrid, and back-lit tactile sensor systems is transforming device architecture across Poland.
Traditional chunky push-buttons are giving way to sleek, edge-to-edge sealed capacitive foil sensors backed by selective haptic metal domes. This hybrid configuration combines a modern, smartphone-like aesthetic with unmistakable physical tactile assurance, essential for safety-critical medical and industrial controllers where operator input must be confirmed without looking away.
Instead of bulky discrete LED clusters that cause hot spots and light bleed, Poznań instrument builders are adopting ultra-thin (0.125mm) Light Guide Film backlighting. By utilizing side-firing micro-SMD LEDs directed across laser-etched micro-dot matrices, symbols and icons illuminate with uniform luminance, consuming up to 60% less power while maintaining an ultra-low profile.
As microcontrollers become denser, silver-screened ink circuits are transitioning toward etched copper Polyimide Flexible Printed Circuits (FPC). Etched copper traces support fine-pitch ZIF connectors (down to 0.5mm pitch) and allow direct SMT soldering of micro-controllers, resistors, and bi-color LEDs directly inside the membrane switch stack, reducing PCB count and system thickness.

Established in March 2009 in Dongguan, Guangdong—the premier global manufacturing hub for electronics hardware—Cevra operates over 2,600 square meters of high-precision cleanroom facilities. Unlike trading desks that broker orders, we carry out all production steps under our audited ISO 9001:2015 quality management system.
Every batch destined for our European clients is verified through extensive testing: Dome Load Actuation Profiling (verifying snap ratio & actuation force), High-and-Low Temperature Environmental Chamber cycling (-40°C to +85°C), Adhesive Holding Tack testing, Tension Peel verification (ASTM D3330), and Electric Pencil Hardness evaluations up to 3H.
Addressing common queries regarding technical specifications, customs compliance, testing standards, and logistics to Greater Poland.
We provide multiple shipping routes customized to project schedules. For rapid prototype verification and fast-track production batches, air express (DHL, FedEx, UPS) delivers directly to Poznań facilities within 4 to 6 business days from dispatch. For cost-effective serial production, the direct China-Europe Railway Express (operating via the Małaszewice corridor) delivers bulk pallet shipments to regional distribution hubs within 16 to 20 days. Full export customs documentation, including HS code declarations, EUR.1 origin assistance, and RoHS/REACH compliance declarations, are supplied with every dispatch.
For high-cycle industrial, agricultural, or medical devices manufactured in Poznań, we strongly recommend biaxially oriented PET (such as MacDermid Autotex®). Polyester withstands more than 5,000,000 keystroke actuations without cracking, resists harsh industrial cleaning solvents (isopropanol, acetone, mineral oils), and preserves embossed dome geometry over wide temperature cycles. Polycarbonate (PC) is suitable for non-flexing decorative fascias, display faceplates, and indoor appliances with limited button movement, offering higher optical clarity and lower raw material cost.
To initiate a comprehensive Design for Manufacturability (DFM) review, please provide vector graphics or CAD drawings in DXF, DWG, STEP, AI, or PDF format. Your documentation should ideally outline: overall exterior dimensions, key center coordinates, embossing style (rim emboss, pillow emboss, or flat), circuit schematic with pinout assignment, tail pitch (e.g., 2.54mm or 1.0mm pitch), preferred connector housing (FCI, Nicomatic, or bare ZIF contact), required tactile force (e.g., 280g, 350g), and specific adhesive backing requirements (such as 3M 467MP, 468MP, or 300LSE for low-surface-energy plastics).
Ingress protection is achieved by engineering a continuous perimeter adhesive gasket around the circuit traces, ensuring that fluid cannot penetrate through tail escape vents. By combining closed-cell acrylic spacer tape (e.g., 3M 200MP series), die-cut vent channels routed internally rather than outward, and hydrophobic breathable membranes where atmospheric pressure relief is needed, our assemblies reliably meet IP65, IP66, and IP67 test protocols under EN 60529 standards.
Yes. In addition to custom peel-and-stick sheet dome arrays designed for manual alignment onto rigid PCBs, we manufacture 4-legged cross snap domes and round domes supplied in tape-and-reel packaging (per EIA-481 standards). This allows Poznań electronics manufacturing services (EMS) providers to feed our snap domes directly into high-speed SMT pick-and-place feeders, dramatically lowering manual assembly labor costs and ensuring 100% placement precision.
Every single production batch undergoes 100% electrical continuity and insulation resistance testing (>100MΩ at 100V DC) via computer-controlled automated pin jigs. Tactile force, trip profiles, and snap ratios are tested on calibrated dome load testers. Graphic overlay colors are verified against Pantone / RAL standards using spectrophotometers under standardized D65 lighting booths, and automated CCD cameras check dimensional tolerances to within ±0.05mm.
