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.

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
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)

Stable alignment under thermal variations
Lightweight structures for dynamic positioning
They are often used in:
Interferometers
Space telescopes
Laser scanning systems
In aerospace systems, SiC fork arms are valued for
Lightweight and stiffness under vibration
Resistance to radiation and thermal shock
Structural stability in low-earth orbit conditions
Typical roles include payload supports, gimbal linkages, and optical mounts.
In cleanroom automation environments, SiC fork arms are used as end-effectors or grippers, offering:
Non-conductive, non-particle-generating surfaces
Long service life in abrasive or corrosive environments
Resistance to outgassing in vacuum chambers
As a non-standard precision component, SiC ceramic fork arms are typically customized based on user requirements. Customizable parameters include:
