Ceramic pressure pins for photovoltaic equipment

   PV equipment ceramic pressure pin is a kind of precision ceramic parts applied in the manufacturing process of photovoltaic module, mainly used in the key process link such as cell cutting, welding or lamination. High hardness (second only to diamond and cubic boron nitride), excellent abrasion resistance, suitable for long-term high-frequency use, outstanding high-temperature resistance, stable operation up to 1000 ℃ in the air, protective atmosphere up to 1400 ℃, low coefficient of thermal expansion (3.2x10:/ ℃), thermal shock resistance, adapt to the rapid temperature change of the environment of photovoltaic equipment.

   Through the mixing, injection, degreasing, sintering and other steps to achieve high-precision near-net molding, suitable for miniaturization of the production of compression needles, silicon powder billet after nitriding, lower process temperature (1200-1400 ℃), suitable for complex shapes of the compression needle molding, the densification of about 79%, need to be followed by the hot compression of the sintering to enhance the strength.

   CeramicsTimes Corporation's ceramic press pins for photovoltaic devices are developed by a superb team of experts consisting of CeramicsTimes professors and PhD's, with advanced ceramic preparation and processing technologies, mastering the world's leading key processes in the manufacture of advanced ceramic materials from powder formulation and treatment, molding, billet processing, sintering, precision machining and precision grinding. Experts respectively research: nitride, oxide, carbide and other advanced ceramic materials and composite ceramics; applied for more than 30 Chinese patents. The products can be customized according to drawings and are widely sold to more than 50 countries and regions around the world.

• Exceptional Mechanical Strength and Wear Resistance: Capable of withstanding immense pressure and friction. For instance, silicon nitride ceramics exhibit compressive strengths exceeding 1500 MPa, with some products surpassing 2200 MPa. 
• Superior thermal stability: Maintains consistent performance in high-temperature environments. Silicon nitride ceramics can operate at temperatures exceeding 1400°C, while aluminum oxide ceramics withstand temperatures around 1200°C. 
• Excellent Electrical Insulation and Chemical Inertness: Photovoltaic ceramic materials are inherently superior insulators, preventing electrical interference. They also exhibit corrosion resistance and withstand exposure to various chemicals.
• Low Density and High Precision: Ceramics have lower density than steel, reducing inertia in high-speed moving components. Through precision machining, dimensional accuracy can reach micrometer levels (e.g., ±0.003mm).

• Material: Photovoltaic welding ceramic press pins are usually made of alumina or other high-performance ceramic materials, which have good mechanical strength and thermal stability.
• Size: Ceramic welding pins can be customized according to different application requirements to meet the needs of different welding equipment and components.
• Temperature resistance range: Photovoltaic welding ceramic press pins can work stably in high-temperature environments, with a typical temperature resistance range of over 1000 ℃.
• Insulation performance: Ceramic welding pin has high insulation resistance, which can effectively prevent current leakage during the welding process.

• Welding and Encapsulation Processes: Employed in precision welding fixtures during cell series welding or module lamination. They ensure accurate workpiece positioning while preventing weld slag adhesion and current shunting through their high-temperature resistance and insulation properties, thereby guaranteeing weld quality.
• Precision Machining and Inspection: Function as positioning pins for high-precision spindles or guide rails in machining equipment like ceramic milling machines. As PV module power increases, machining precision requirements for components like alumina ceramic insulators and silicon nitride heat sinks reach ±0.01 mm levels. 
• Automated Production Lines: In automated modules for handling and assembly, they serve as wear-resistant, corrosion-resistant guide shafts and connectors. This ensures long-term stable production line operation and reduces maintenance downtime.
