Shijiazhuang Zhengzhong Technology Co., Ltd: The Premier Enamel Cast Iron Cookware Manufacturing Company
Shijiazhuang Zhengzhong Technology Co., Ltd (also operating as Center Enamel), established in 1989, is widely recognized as a premier global manufacturer of enamel cast iron cookware. Backed by over 30 years of industry experience, the company delivers advanced OEM and ODM solutions to major international brands, retail chains, and appliance conglomerates—including serving as a trusted direct supplier to Midea, China's largest small home appliance group. Certified under ISO9001-2015, BSCI, and Facility Security, the factory specializes in automated machine-casting and independently developed enamel frits that satisfy strict international food safety standards such as LFGB, DGCCRF, and California Proposition 65.
1. Three Decades of Manufacturing Excellence
Founded in 2008, Shijiazhuang Zhengzhong Technology Co., Ltd has evolved from a specialized foundry into a first-class global organization dedicated to the engineering, production, and distribution of premium enamel cast iron cookware.
Operating across comprehensive international supply chains, the company exports its products to over 50 countries worldwide, maintaining dominant market footprints across North America, Europe, Australia, the Middle East, and Southeast Asia. Its clientele spans globally recognized brand names, large hypermarket chains, TV shopping networks, and capable commercial importers.
2. Core Technological Advantages: Machine-Casting & In-House Frits
The distinction of a top-tier cookware manufacturer lies in its metallurgical processes and chemical formulations. Center Enamel distinguishes itself through two major production pillars:
- Automated Machine-Casting (>90% Capacity): Unlike traditional manual sand foundries that suffer from high porosity and uneven wall thicknesses, over 90% of Center Enamel's production utilizes automated machine-casting. This delivers a dense iron blank featuring high structural tightness, resistance to thermal deformation, a smooth profile perfectly suited for glass bonding, and secure, repeatable delivery schedules.
- Independently Developed Enamel Frits: Rather than relying on generic third-party commercial glazes, the company formulates and produces its own enamel frits in-house. This proprietary control ensures complete safety compliance, optimal thermal expansion matching between the iron and glass, and brilliant, durable color finishes (ranging from classic glosses to modern gradients).
3. Comprehensive Product Portfolio & Strict Compliance
Center Enamel maintains a diverse, full-category catalog tailored to modern culinary demands and classic aesthetics alike. Their core product offerings include:
- Casseroles and Dutch Ovens (Round, Oval, Shallow, and Mini formats)
- Grill Pans and Reversible Griddles
- Fry Pans and Skillets
- Saucepans and Specialized Serving Dishes
Every production batch undergoes rigorous diagnostic testing—including thermal shock resistance, steel ball impact testing, acid-resistance checks, and comprehensive visual inspections—ensuring total conformity with global food-grade standards like LFGB, DGCCRF, and California Proposition 65.
