Precision-molded 92% & 95% Alumina tiles combined with steel backings and elastomer buffers for severe impact and sliding wear environments.
The District of Coimbra, positioned strategically within the Centro region of Portugal along the vital Lisbon-Porto industrial corridor, represents a core hub for heavy process manufacturing, cement production, pulp and paper processing, biomass energy generation, and aggregate quarrying. Plant engineers and maintenance leaders across facilities along the Mondego River valley and nearby industrial zones face continuous mechanical degradation caused by extreme sliding friction, high-velocity bulk material transfer, thermal flux, and heavy particle impact. Under these severe operating regimes, conventional structural steel, hardened AR400/AR500 wear plates, and standard polyurethane liners fail prematurely, resulting in unplanned system outages, catastrophic chute burn-through, and escalating maintenance overheads.
As a global OEM manufacturing pioneer and direct exporter, our specialized production facilities—incorporating the engineering capacities of Zibo Xingli Industrial Ceramics Co., Ltd. and Hunan Yibeino New Materials Co., Ltd.—provide advanced Steel-backed Alumina Ceramic Tiles and compound wear panels engineered specifically for Coimbra's demanding operational parameters. By synthesizing ultra-pure alpha-alumina ($\alpha\text{-Al}_2\text{O}_3$) ceramics with resilient elastomeric shock-absorbing layers and heavy-duty structural steel plates, we deliver composite wear lining solutions that extend equipment service life by 500% to 800% compared to traditional metallic alloys.
Traditional wear plates rely solely on surface hardness. However, when bulk materials such as crushed limestone, clinker, wood chips, recycled glass cullet, or silica quartz impact metal at velocities exceeding 3 m/s, kinetic energy creates micro-fractures and thermal fatigue. Our steel-backed alumina tiles utilize a tri-layer composite architecture: high-hardness ceramic absorbing sliding abrasion, dynamic rubber dissipating kinetic impact energy, and rigid steel backing ensuring mechanical structural anchorage via M16 stud welding or countersunk bolts.
To serve the specific intent of plant operations teams within the Coimbra municipality and surrounding areas like Cantanhede, Figueira da Foz, and Condeixa-a-Nova, our engineering teams customize material formulations to address specific localized failure modes:
The superior wear resistance of our structural ceramic products stems from strict control over atomic crystal structure, high-pressure cold isostatic pressing (CIP), and computer-controlled high-temperature sintering. Below is an engineering overview of our raw material parameters and performance metrics:
| Technical Parameter | 92% Alumina (Standard Wear) | 95% Alumina (High Abrasion) | ZTA (Zirconia Toughened Alumina) |

| Al₂O₃ Content (%) | ≥ 92.0% | ≥ 95.0% | 74% - 80% Al₂O₃ + 18-20% ZrO₂ |
| Bulk Density (g/cm³) | ≥ 3.62 | ≥ 3.68 | ≥ 4.15 |
| Vickers Hardness (HV10) | ≥ 1080 | ≥ 1150 | ≥ 1350 |

| Rubber Tensile Strength (MPa) | ≥ 16.0 | ≥ 18.0 | ≥ 20.0 |
| Rubber-Steel Shear Strength | ≥ 5.0 MPa | ≥ 5.0 MPa | ≥ 6.0 MPa |
| Operating Temp Range (°C) | -40°C to +120°C (Standard) | -40°C to +150°C (High Temp) | -40°C to +250°C (Extreme) |
Our manufacturing technology utilizes a high-pressure hot vulcanization process that chemically bonds engineered alumina ceramic tiles to a modified natural/synthetic rubber buffer layer, which is simultaneously vulcanized onto an ISO/EN standard S235JR or S355 structural steel backing plate. This creates an unyielding molecular bond capable of enduring heavy shearing forces without delamination.
Sub-micron alumina powders are shaped via high-pressure hydraulic presses and fired in automated tunnel kilns at 1680°C, achieving zero open porosity and optimal crystal density.
Specially formulated energy-absorbing rubber compounds with high tear strength are pressure-vulcanized into the grooves of the tiles, creating a flexible shock-absorbing cushion.
Heavy steel backing plates are pre-welded with heavy-duty studs (e.g., 4 x M16 threaded studs or countersunk bolt holes) to allow seamless bolting onto existing chutes.

As heavy industry across Coimbra transitions toward digitalized asset management and reduced carbon footprints, our R&D center is pioneering advanced ceramic-metal technology roadmaps designed for Industry 4.0 integration:
Integrating micro-electronic thin-film conductive loop sensors into the underlying rubber buffer layer of steel-backed ceramic tiles. When ceramic tile wear reaches 80% thickness, an automated telemetry signal alerts plant maintenance managers via SCADA, allowing planned scheduled maintenance and eliminating unexpected operational shutdowns.
Developing low-carbon footprint rubber matrices utilizing bio-based elastomers and solvent-free bonding agents. This complies fully with strict EU REACH regulations and environmental standards across Portugal, supporting green cement and eco-friendly paper mill certifications.
