Our commitment to quality begins with the selection of raw materials and extends through every phase of manufacturing, adhering to stringent international standards such as ISO and ANSI for reliability and consistency.
Process Steps:
1. Material Sourcing & Calcination
High-purity natural mica is carefully sourced and then subjected to precise calcination at elevated temperatures. This thermal treatment removes volatile components, enhances the crystal structure, and improves the mica's thermal stability and dielectric properties. Ceramic binders and specialized additives are also prepared.
2. Mixing & Forming
The calcined mica powder is homogeneously blended with proprietary ceramic binders and additives. This optimized mixture is then formed into specific shapes or sheets using advanced techniques such as high-pressure dry pressing, slip casting, or extrusion, depending on the final product geometry and application requirements.
3. Sintering & Densification
The formed green bodies undergo a precise sintering process in high-temperature furnaces under controlled atmospheric conditions. This critical step promotes ceramic bonding, densification, and crystallographic transformation, imparting the material's final mechanical strength, thermal resistance, and insulation properties.
4. Precision Machining & Finishing
Post-sintering, advanced CNC machining and grinding techniques are employed to achieve the exact dimensional tolerances and surface finishes required by industrial specifications. This ensures perfect fit and optimal performance in complex assemblies, often eliminating the need for further post-processing by the client.
5. Quality Control & Testing
Every batch undergoes rigorous quality inspection and testing, including dimensional checks, thermal performance analysis, dielectric strength tests, and mechanical property verification. Adherence to ISO 9001 and other relevant industry standards (e.g., ASTM, DIN) ensures consistent product quality and an extended operational lifespan for the end-user.
This meticulous process guarantees that our ceramics provide exceptional service life and demonstrate significant advantages in typical application scenarios, such as superior energy saving capabilities due to effective thermal insulation and unparalleled corrosion resistance in harsh chemical environments.
