SiC ceramic fork custom-made precision structural component, handle wafers, optical component
Abstract of SiC ceramic fork
SiC Ceramic Fork Arm is a structural component made from advanced silicon
carbide ceramic material. It is primarily used in precision equipment requiring high rigidity, low thermal expansion coefficient, and high wear resistance. The "fork arm" shape is commonly found in high-end optical devices, semiconductor processing equipment, and automated handling systems, serving as a support, positioning, transmission, or clamping element. Compared to traditional metal materials, silicon carbide ceramic offers significant advantages in mechanical performance, thermal stability, and corrosion resistance, and has gradually become a key functional component in modern high-precision manufacturing.
