99 Alumina Ceramic Custom Finishing


Alumina ceramic sheet customization

Customized Alumina ceramic suction cups are specially designed for use in photovoltaic (PV) systems, which convert sunlight into electricity. These suction cups are made from a high-quality alumina ceramic material, known for its exceptional strength, durability, and resistance to high temperatures. The customization aspect allows manufacturers to tailor the suction cups to meet specific requirements, such as size, shape, and surface texture, to ensure optimal performance in PV applications.


Here are some key points about customized alumina ceramic suction cups for photovoltaic equipment:

  1. Material Properties:

    Alumina ceramic is a highly durable and robust material that can withstand harsh environmental conditions, including extreme temperatures, UV radiation, and moisture. This makes it well-suited for outdoor PV installations.

  2. Temperature Resistance:

    Alumina ceramic suction cups can operate effectively within a wide temperature range, typically from -40°C to 200°C (-40°F to 392°F). This temperature tolerance ensures reliable performance even in challenging climates.

  3. Customization Options:

    The ability to customize these suction cups allows manufacturers to create solutions that meet the specific needs of different PV systems. This includes varying the size, shape, and surface texture of the suction cups to optimize their adhesion to different surfaces and ensure a secure hold.
