Product Details
1.Core Advantages
1.1High porosity and uniform pore size
High porosity and uniform pore size enable low resistance for both gas and liquid flow through applications，Good rigidity and dimensional stability.Ceramic material has a high hardness (Mohs hardness ≥8), can withstand high temperatures (up to over 500°C), and is resistant to various acid and alkali corrosions. It has a long service life, which is 3 to 5 times that of traditional suction cups.
1.2 High porosity and uniform pore size
Excellent chemical resistance in both acid and alkaline conditions，Low resistance for both gas and liquid flow through application.The micron-level porous structure ensures uniform suction distribution. Even if the workpiece surface has slight unevenness, it can still firmly adhere. It is particularly suitable for ultra-thin and fragile materials such as glass and silicon wafers.
1.3 Uniform pore sizes and high surface areas
Uniform pore sizes and high surface areas，Good acid and alkali resistance.The surface is smooth and not prone to material adhesion or clogging, significantly reducing the frequency of cleaning and shutdown maintenance, and lowering operating costs.
2.Excellent Material and Durability Performance
2.1 Performance and long-term durability
The product boasts exceptional material performance and long-term durability based on alumina ceramic’s inherent physical and chemical properties. With a Mohs hardness of no less than 8, the material features high rigidity and excellent dimensional stability, resisting deformation, abrasion and impact during long-term high-frequency operation.
2.2outstanding high-temperature resistance
It realizes outstanding high-temperature resistance, being capable of continuous stable operation in environments above 500°C without structural deformation or performance attenuation. Besides, it possesses great chemical corrosion resistance, maintaining stable working performance in acid-base corrosive atmospheres. Its overall service life is 3 to 5 times longer than traditional rubber and metal suction cups.
2.3 Excellent insulation
In addition, high-purity alumina ceramic has excellent insulation, dust-free and non-pollution characteristics, fully complying with the strict cleanliness standards of semiconductor and optoelectronic clean workshops, and completely avoiding secondary contamination to ultra-precision workpieces.
3.Uniform and Stable Vacuum Adsorption Performance
3.1 Core performance
The core performance advantage of the suction cup lies in its superior vacuum adsorption uniformity and stability brought by the unique microporous structure. The pore size and porosity (35%-40%) are precisely controlled during production, forming a dense, flat and consistent vacuum adsorption surface. Different from traditional porous suction cups with concentrated air holes and uneven pressure distribution, its three-dimensional interconnected microporous network evenly disperses negative pressure across the entire working surface.
3.2This effectively eliminates
This effectively eliminates local stress concentration, enabling seamless and fitting adsorption on ultra-thin, soft and flexible workpieces. It thoroughly avoids common processing defects including workpiece warping, surface indentation, scratching and edge upwarping. Meanwhile, the reasonable microporous structure brings fast vacuum response speed and stable air pressure output, perfectly adapting to high-speed reciprocating handling and fixed precision processing procedures.
4.Zero-Damage and High-Precision Positioning Performance
4.1 Outstanding zero-mark
This series of ceramic vacuum suction cups delivers outstanding zero-mark and zero-damage adsorption performance as well as high-precision positioning capability. After multiple ultra-precision surface grinding and polishing treatments, the suction plane achieves ultra-high flatness and smoothness without burrs, protrusions or uneven areas. It can stably adsorb and fix various fragile and easily deformed workpieces, such as ultra-thin semiconductor wafers, flexible OLED screens, ultra-thin glass substrates, precision circuit boards and tiny electronic components. In terms of positioning performance.
4.2 Electrostatic compatibility optimization
The product supports customizable zoning air suction design and electrostatic compatibility optimization. It can be flexibly matched with different vacuum systems and process parameters, meeting the ultra-high precision positioning and fixing requirements of cutting, polishing, surface testing and automated transferring processes in precision manufacturing.
4.3 Excellent comprehensive operational performance
Compared with traditional suction cup products, alumina microporous ceramic vacuum suction cups show more excellent comprehensive operational performance and industrial adaptability. Traditional rubber suction cups are prone to aging, permanent deformation and air leakage after long-term use, and cannot withstand high-temperature and high-cleanliness working environments. Conventional metal porous suction cups suffer from uneven pore sizes and poor adsorption consistency, which easily affects product processing accuracy.
