4. Manufacturing Process of Cast Iron Round Casserole Dish

Material Selection: Use of high-grade GGG40 spheroidal graphite iron (EN-GJS-400-15) ensures robust structure and optimal heat retention.
Smelting & Pouring: Alloyed cast iron melted at 1450–1500℃ and poured into precision green-sand or resin molds. (Certified ISO 9001:2015 process)
Core Removal & Cleaning: After cooling, sand core is ejected, and surface cleaned with high-pressure shot blasting.
CNC Machining: Machining of pot brim and base to tight tolerance (<0.3mm flatness) guarantees fine lid fit and uniform thickness.
Enamel Coating: Application of BPA-free, food-grade enamel in three coats, each fired at 800–860℃ for chemical bonding, anti-corrosion, and gloss enhancement (complying ANSI/NSF/SGS/FDA).
Quality Inspection: Each casserole dish undergoes pressure, thickness, coating adhesion, and food safety tests (SGS, FDA, LFGB certified).
Packing & Delivery: Final product packed according to export standard. Custom OEM/ODM branding, color, and packaging available.

Average Production Lead Time: 22–28 business days per 5,000 sets. Express and bulk ocean shipment supported.
