LONGYI specializes in advanced ceramic manufacturing, focusing on fine ceramics and precision molding injection parts. We deliver high-quality products through comprehensive processes, from powder preparation to post-processing.
High-Purity advanced ceramic Powder Preparation
We use high-purity ceramic materials like oxides, nitrides, and carbides. Nano-scale or micro-scale ceramic powders are prepared using chemical synthesis, mechanical milling, and spray drying. Precise mixing ensures uniformity and stability.
Versatile Forming Techniques
LONGYI offers multiple forming methods tailored to fine ceramics:
Ceramic Powder Injection Molding (C-PIM): Ideal for complex shapes, C-PIM combines ceramic powders with binders for high-precision molding injection parts.
Press Forming: Isostatic pressing ensures uniform density and performance.
Pre-Sintering and Sintering Processes
Organic binders are removed during debinding to prevent defects. Sintering methods include:
Conventional Sintering: Forms dense structures.
Hot Pressing: Enhances density and strength.
Microwave Sintering: Reduces time and energy usage.
Atmosphere-Controlled Sintering: Prevents oxidation with controlled gases.
Precision Machining for advanced ceramic
LONGYI provides advanced machining for fine ceramics:
CNC 5-Axis Machining: Produces complex geometries with high precision.
Grinding and Polishing: Achieves nanometer-level surface finishes.
Laser Machining: Enables precise cutting and engraving.
Rigorous Testing and Measurement
LONGYI ensures every fine ceramics product meets strict standards. Collaboration with iST enhances testing capabilities.
Precision Measurement: Ensures dimensional accuracy and tolerance.
Performance Testing: Evaluates density, hardness, and thermal properties.
Microstructure Analysis: Uses SEM and TEM for detailed observation.
Post-Processing and Assembly
LONGYI offers post-processing for fine ceramics:
Ceramic Metallization: Adds conductivity for electronic applications.
Ceramic Brazing: Joins ceramics and metals for complex structures.
