Explore our top-tier engineered ceramic components, precision-molded and sintered for extreme thermal, wear, and dielectric environments.
Integrating full-process advanced technical ceramics engineering—from nano-powder compounding and green body molding to diamond precision grinding.
Founded in 2003, Yixing Qiangguang Ceramic Materials Co., Ltd. stands as a premier enterprise dedicated to the research, development, custom manufacturing, and precision engineering of advanced ceramic materials. Situated at the heart of China's technical ceramic industrial capital, Yixing, the company represents a rare group of global manufacturers possessing a fully integrated end-to-end industrial value chain.
Unlike conventional processors who rely on third-party green bodies or pre-fabricated ceramic blanks, our capabilities cover all core production phases: ultra-fine powder synthesis & slip preparation, high-pressure dry pressing, Cold Isostatic Pressing (CIP), Ceramic Injection Molding (CIM), high-temperature vacuum sintering, and multi-axis CNC diamond machining. This vertically integrated control ensures absolute batch-to-batch consistency, total material traceability, and unprecedented molding precision.
Our expansive ceramic portfolio encompasses structural and functional engineering materials, including Zirconia (ZrO2), Yttria-Stabilized Zirconia (YSZ), Magnesia-Stabilized Zirconia (MSZ), High-Purity Alumina (Al2O3), Silicon Nitride (Si3N4), Aluminum Nitride (AlN), Boron Nitride (BN), Silicon Carbide (SiC), Magnesium Oxide (MgO), and Aluminium Titanate (Al2TiO5).
Delivering dimensional fidelity and structural integrity through tailored powder compaction, injection molding, and sub-micron finishing techniques.
Ideal for complex 3D geometric components with intricate internal channels, threads, and thin walls. CIM combines organic thermoplastic binders with sub-micron ceramic powders. After automated molding, multi-stage solvent and thermal debinding guarantee defect-free sintering with density exceeding 99.5% theoretical limits.
Utilizing hydrostatic fluid pressure up to 300 MPa, CIP yields extremely uniform green body density. This eliminates internal stress gradients, enabling distortion-free sintering of large-scale rods, thick tubes, and structural blanks prior to precision CNC diamond grinding.
Post-sintering ceramics exhibit hardness second only to diamond (Vickers Hardness HV 1200-2000). Our state-of-the-art 5-axis CNC grinding machining centers utilize resin-bonded and metal-bonded diamond tooling to achieve geometrical tolerances of ±0.001mm and surface roughness of Ra < 0.05 µm.

Answers to common technical queries regarding precision ceramic molding tolerances, material selection, production lead times, and global shipping.
In as-sintered state (via Ceramic Injection Molding or Dry Pressing), typical linear tolerances range between ±0.2% and ±0.5%. However, using post-sintering diamond CNC grinding, lapping, and honing, we routinely guarantee micro-tolerances down to ±0.001mm (1 micron), with surface roughness Ra < 0.05 µm and cylindrical concentricity within 0.002mm.
Zirconia offers higher flexural strength (>1000 MPa) and superior surface smoothness, making it preferred for medical instruments, shaft seals, and room-temperature wear components. Silicon Nitride (Si3N4), while slightly lower in room-temperature strength, maintains exceptional mechanical properties up to 1200°C and possesses outstanding thermal shock resistance and lower density (3.2 g/cm³ vs 6.0 g/cm³), rendering it superior for high-speed bearings and thermal cycle environments.
For rapid prototypes requiring custom green-state machining, sample dispatch takes approximately 7 to 14 business days. For volume production utilizing custom injection or pressing tooling, mold fabrication takes 15-20 days, followed by mass production runs of 2 to 3 weeks depending on batch volume and finishing requirements.
Yes. Our engineering team conducts thorough DFM evaluations on client 3D STEP/IGES models to identify potential sintering distortion risks, sharp interior radii, or excessive machining walls. We recommend optimal ceramic formulations and minor geometric tweaks to maximize component lifespan while minimizing production cost.
