Core Technologies and Capabilities
Bulletproof Ceramic Material
System Design
​
Ciheng Technology has built a parallel material system design capability encompassing both adjustable and curable types, based on two advanced bulletproof ceramic materials: silicon carbide (SiC) and boron carbide (Bâ‚„C).
On one hand, the company can perform targeted design and optimization using different proportions of silicon carbide/boron carbide composite formulations, targeting different protection levels, weight limitations, and application scenarios to meet customers' customized needs in balancing lightweighting, protective capabilities, and cost control.
On the other hand, the company has simultaneously established a mature and solidified material formulation and process parameter system for the stable production of standardized products, ensuring consistent protective performance and structural reliability under mass production conditions.
Through this parallel model of "customized design capability + curable formulation productization," the company can simultaneously serve personalized project needs and large-scale supply scenarios.
Ceramic Forming and
Pressureless Sintering Process Control
​
The company's core bulletproof ceramic components are manufactured using a pressureless sintering process.
Compared to hot pressing or reaction sintering, pressureless sintering offers the following significant advantages in bulletproof ceramic applications:
​
**High Degree of Dimensional and Structural Freedom:** Suitable for the stable manufacturing of complex-sized and multi-specification ceramic parts, facilitating product serialization and engineering expansion.
​
**Good Material Purity and Microstructure Uniformity:** Beneficial for obtaining a uniform and dense ceramic microstructure, improving the stability and repeatability of protective performance.
​
**Suitable for Batch Production and Consistency Control:** Stable process window, facilitating consistent product performance in large-scale production.
​
**More Beneficial for Balancing the Overall Performance of Bulletproof Ceramic:** Achieving an engineering-controllable balance between hardness, fracture behavior, and energy dissipation characteristics.
Through systematic control of powder particle size distribution, forming process parameters, and sintering regime, the company has established a stable pressureless sintering process system for bulletproof ceramic applications.
Protective Structure Integration
with Ceramic-PE Composite System
​
In designing ballistic inserts, the company does not treat ceramics as isolated components, but rather as part of the overall protective system.
The product structure is optimized at the system level around:
· Ceramic fragmentation and core erosion capability
· PE energy absorption and back bulge control capability
· Ceramic-composite layer interface stability.
Through comprehensive design of ceramic fragmentation modes, energy transfer paths, and the synergistic operation of the composite structure, the company achieves an overall balance between protective performance, weight control, and structural integrity, rather than simply stacking the properties of individual materials.
Product Design Capabilities Oriented Towards
Engineering and Large-Scale Production
​
Ciheng Technology's bulletproof ceramic products are designed from the outset with engineering replicability and large-scale application in mind.
During product development, the company focuses on:
· The repeatability of process parameters
· Performance consistency under mass production conditions
· Process versatility across different product specifications
· Compatibility with subsequent composite and assembly processes
Through these engineering design principles, the company's bulletproof insert products possess the fundamental capability to transition from R&D prototypes to stable mass production.
