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.

Design and Manufacturing of SiC Ceramic Fork Arms

Structural Design

SiC fork arms are custom-designed according to application requirements. Common forms include "U-shaped" or "T-shaped" arms used for:

• Wafer handling

• Probe card positioning

• Optical module support

Key considerations in design include:

• Load capacity and stress distribution

• Thermal stress compensation

• Precision mounting interfaces

• Cleanroom compatibility

Processing Techniques

The manufacturing process involves several critical steps:

• Powder preparation

• Forming (dry pressing, isostatic pressing, or casting)

• Sintering (e.g., pressureless sintering, reaction bonding)

• Machining (grinding, laser drilling, EDM)

• Surface finishing (polishing, coating, laser marking)
