The Science of Premium Cast Iron
1. Precision Vacuum Casting
Our proprietary vacuum casting process eliminates microscopic air bubbles, resulting in a high-density iron base with superior wall strength and structural integrity.
2. 900°C Porcelain Enameling
A rigorous three-coat, three-fire process at 900°C fuses premium glass frit to the iron core, creating a brilliant, 0.8–1.5mm thick surface that resists bacteria and fading.
3. Hand Finishing & QC
Exteriors are meticulously hand-polished by skilled craftsmen. Every unit undergoes strict dimensional checks and water testing to ensure flawless performance.
