Inside Our Manufacturing Process
From raw iron ore to high-gloss enameled masterpieces, our strict control over every production step ensures uncompromising quality.
1. Precision Casting
Using high-grade iron ore, our vacuum casting process ensures superior heat retention and structural integrity without microscopic air bubbles.
2. 900°C Enameling
High-temperature firing (900°C) fuses premium porcelain to the iron core, creating a brilliant surface that resists scratches, chemicals, and bacteria.
3. Hand Finishing
Exteriors are meticulously hand-polished by skilled craftsmen, ready for custom paint or a classic smoothed iron look.
