The price is primarily driven by panel thickness (typically 12mm to 18mm) and the complexity of the CNC carving pattern. Deeper patterns require thicker base boards and longer machining times, increasing the cost. Additionally, the core material density (aim for 700-800 kg/m³) determines the panel's impact resistance. For moisture-prone areas, specify MR (Moisture Resistant) green core MDF, which prevents swelling in humid environments. Always request a cross-section sample to inspect the consistency of the fiber distribution.
