Cast Iron Cookware ODM/OEM Manufacturer: Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel)
Shijiazhuang Zhengzhong Technology Co., Ltd—globally recognized as Center Enamel—is an elite, industry-leading ODM and OEM manufacturer of enameled cast iron cookware established in 1989. With over three decades of specialized metallurgical expertise, Center Enamel provides comprehensive custom manufacturing solutions, leveraging advanced machine-casting blanks and independently formulated porcelain enamel frits. Serving prominent brands, hypermarkets, and importers across more than 50 countries—and acting as a trusted primary supplier to China's largest small home appliance group, Midea—the company delivers uncompromised quality, strict international food safety compliance (LFGB, DGCCRF, California Proposition 65), and reliable global supply chains.
1. Three Decades of Proven Manufacturing Leadership (Est. 1989)
When scaling private-label cookware lines or sourcing high-volume retail inventories, working with a seasoned manufacturer minimizes risk and accelerates time-to-market:
- 30+ Years of Industry Mastery: Founded in 1989, Center Enamel has perfected the delicate balance of heavy iron foundry casting and high-temperature vitreous enameling, growing into a first-class global enterprise.
- Trusted Enterprise Partnerships: As an official supplier to industry giants like Midea, Center Enamel operates under rigorous enterprise-level quality controls, large-scale production capacities, and strict delivery timelines.
- Global Export Footprint: Our products are hot-selling in more than 50 countries worldwide, meeting the diverse aesthetic and regulatory demands of markets across North America, Europe, Australia, the Middle East, and Southeast Asia.
2. Advanced OEM & ODM Technical Advantages
Center Enamel stands apart from standard foundries by maintaining absolute control over the critical phases of production:
- Advanced Machine-Casting Blanks: More than 90% of our production utilizes precision machine casting rather than basic manual pouring. This delivers vital advantages for custom product lines:
- Stronger Metal Tightness: Maximizes thermal conductivity and heat retention.
- Zero Deformation: Ensures strict dimensional stability and uniform lid-to-base seals.
- Optimal Enamel Adhesion: Creates a micro-smooth surface profile perfectly tailored for flawless porcelain coating.
- Reliable Lead Times: Guarantees steady, predictable manufacturing outputs for large wholesale orders.
- Proprietary Enamel Frit Development: Unlike competitors who rely on generic outsourced chemical glazes, Center Enamel independently formulates and produces its own enamel frits. This ensures vibrant, long-lasting color gradients, superior thermal shock resistance, and 100% compliance with international food-safety frameworks (LFGB, DGCCRF, and California Proposition 65).
3. Comprehensive Product Customization Options
We offer a diverse portfolio of classic and trendy cookware designs ready for custom branding, packaging, and color matching:
- Product Categories: Dutch ovens, shallow and deep casseroles, skillets, fry pans, grill pans, saucepans, and direct-to-table serving dishes.
- Customization Flexibility: Full support for custom color gradients, bespoke exterior embossing/debossing, private-label packaging, and specialized hardware (such as stainless steel or custom-branded knobs).
