Welcome to our comprehensive guide on Engineering & Solutions for C/C composites.

Key Advantages of C/C Springs in Brazing

• Lightweight Yet Powerful: Delivers high compressive force while reducing fixture weight, improving handling and efficiency.
• Versatile Shapes & Customization: Available in coil, E-shape, and flat plate designs to suit various brazing needs.
• Energy Efficiency: Reduces heat capacity demands, cutting energy consumption and processing costs.
• Minimized Thermal Expansion: Maintains dimensional stability, ensuring precise force application across multiple heat cycles.

Energy Consumption Reduction with C/C Springs

Switching to C/C fixtures can drastically reduce energy costs and processing times:

• Lighter Jigs = Lower Heat Capacity Needs: Traditional metal jigs absorb more heat, increasing energy consumption. C/C jigs, which are up to 70% lighter, reduce this demand.
• Faster Heat Treatment Cycles: The reduced thermal mass allows for shorter heating and cooling times, improving overall production efficiency.
• Energy Savings: Based on real-world brazing tests, switching from metal to C/C fixtures leads to a reduction in heat capacity requirements, lowering operational costs.
• Optimized Thermal Efficiency: Traditional metal fixtures waste most of the applied heat, delivering minimal energy to the actual parts. In contrast, Across-CFC’s C/C fixtures transfer over 50% of that energy directly to the target components, maximizing thermal efficiency and process performance.

The Role of C/C Springs in Brazing Fixtures

• Controlled-Force Weighting: Ensures proper alignment and contact of parts during heating.
• Stable Across Multiple Heat Cycles: Maintains consistent pressure without weakening over time.
• Superior to Metal Springs: Unlike traditional metal fixtures, C/C springs do not degrade from fatigue or thermal stress.

Key Benefits of C/C Springs in Brazing Applications

• Enhanced Joint Integrity: Provides even pressure distribution, minimizing brazing defects and inconsistencies.
• Significant Energy Savings: Reduces heat absorption, cutting down energy costs.
• Improved Processing Efficiency: Faster heat-up and cool-down times accelerate production cycles.
• Lightweight and Ergonomic Design: Less weight and load impact for operator handling.
• Extended Fixture Lifespan: Resists deformation and fatigue, ensuring long-term durability.
• Reduced Maintenance Requirements: Unlike metal fixtures, C/C fixtures do not warp or degrade, maintaining consistent performance with minimal upkeep.

Stress Analysis

For load-bearing C/C structures, we conduct detailed stress analysis and structural optimization.

Key Engineering Areas

• Finite Element Method (FEM) Simulations: Provides predictive analysis of load distribution and stress points.
• Stress & Load Calculations: Ensures safe mechanical integrity under operational conditions.
• Rotational/Centrifugal Force Analysis: Prevents structural failure in high-speed applications.
• Thermal Expansion Effects: Analyzes deformation risks under high temperatures.

Why C/C?: Unlike metals, C/C retains its strength and elasticity at high temperatures, minimizing failure risks.
