products details
Granite is the preferred material for high-precision bases in photovoltaic (PV) cell production equipment. Thanks to its exceptional strength, rigidity, and near-zero porosity, granite provides unmatched dimensional stability and vibration resistance-both of which are essential for achieving the accuracy required in solar cell manufacturing processes.

Why Choose Granite for PV Cell Manufacturing?
Superior Hardness & Rigidity
With a Mohs hardness of 7 and a dense crystalline structure, granite ensures stable support for high-precision components. It effectively minimizes flexing, warping, or vibration during processes such as brightfield and darkfield etching of photovoltaic cell substrates.
Minimal Absorption, Maximum Durability
Granite's ultra-low water absorption rate (≤ 0.1%) makes it highly resistant to oil, water, and chemical corrosion-perfect for cleanroom and high-moisture environments. This durability also protects against wear during continuous grinding, chipping, or mechanical stress.
Excellent Thermal Stability
The low thermal expansion rate of 7–8 ppm/°C helps granite maintain its structural integrity and precise geometry even in fluctuating temperatures. This ensures consistently accurate machining and stable performance throughout production cycles.
Efficient Heat Dissipation
Granite also offers efficient thermal conductivity, helping to dissipate heat generated during high-speed machining or laser processing-an important factor in preventing part deformation and maintaining dimensional accuracy.
Long-Term Value
While granite precision bases may carry a slightly higher upfront cost than steel or cast iron, their outstanding longevity, minimal maintenance, and superior performance offer better return on investment over time.
