C/C Composite Molds for High-Temperature Hot Press Furnaces

Case Study: C/C Composite Molds for High-Temperature Hot Press Furnaces

Challenge
Manufacturers operating high-temperature hot press furnaces face persistent issues with traditional graphitemolds:
· Frequent cracking and chipping under combined high pressure and heat
· Rapid strength degradation at temperatures exceeding 1800°C
· Short service life requiring frequent replacement and increased downtime
· Poor dimensional stability leading to inconsistent product quality
These limitations directly impact production efficiency, material costs, and final product performance-especially for

critical applications in advanced ceramics, composite materials, and high-performancecomponents.

Solution
Our C/C (Carbon/Carbon) Composite Molds were engineered to address these pain points, offering asuperior alternative

to graphite for demanding hot press processes:

Key Advantages of C/C Composite Molds:
Superior Strength & Toughness: Resists cracking and chipping even under extreme mechanical stress,
eliminating unexpected failures.
Exceptional Thermal Shock Resistance: Maintains structural integrity through rapid heating/cooling cycles,a critical factor in hot press operations.
High-Temperature Stability: Retains full mechanical strength at 2000°C+, outperforming graphite whichsoftens at elevated temperatures.
Extended Service Life: Delivers 5-20x longer lifespan than graphite molds, drastically reducingreplacement costs and downtime.
Precision & Consistency: Provides superior surface finish and dimensional stability, ensuring tighttolerances and consistent product quality batch after batch.
Process Optimization: Ideal for high-temperature & high-pressure hot pressing, enabling manufacturersto push process limits without compromising mold integrity.
