Granite has become one of the most widely used materials for precision bases in photovoltaic cell production equipment. Thanks to its high strength, rigidity, zero porosity, and thermal stability, granite meets the demanding requirements of solar cell manufacturing and ensures long-term reliability.

Key Advantages of Granite Bases in PV Manufacturing

1. Extreme Strength & Rigidity

With a Mohs hardness of 7 and a dense crystalline structure, granite provides exceptional stability and stiffness. This ensures that precision parts remain absolutely secure, with no flexing or vibration during the brightfield and darkfield etching process. The result is improved machining accuracy and higher-quality photovoltaic cells.

2. Low Absorption & Corrosion Resistance

Granite has a water absorption rate of just 0.1%, making it highly resistant to corrosion, wear, and contamination from oils or coolants. Its low porosity also ensures excellent performance in grinding, polishing, and chipping processes without surface degradation.

3. Thermal Stability for Precision Accuracy

Granite offers a very low thermal expansion rate of 7–8 ppm/°C, maintaining dimensional integrity across wide temperature ranges. This minimizes thermal distortion and guarantees consistent accuracy in solar cell production.

4. Heat Dissipation & Process Safety

As an effective heat conductor, granite prevents excessive heat build-up during machining, protecting delicate parts and extending the life of production equipment.
