As a professional manufacturer specializing in the R&D and production of aluminum disc circles, Haomei Aluminum has been deeply involved in the field of cookware substrates for many years. With stringent technical standards and precise process control, we provide high-performance aluminum circles solutions to cookware manufacturers worldwide. We firmly believe that the core of high-quality cooking pots stems from the superior quality of the substrate. Through end-to-end technological innovation, we ensure that every aluminum disc is a safe, efficient, and durable cooking medium.
In the material selection process, we strictly adhere to the EU standard EN 851 for aluminum and aluminum alloy discs used in cooking utensils and the US standard ASTM B479 for aluminum in food contact. We select high-quality aluminum alloy substrates such as 1060 and 3003 to ensure that our aluminum circles for cooking pot products fully comply with international food contact safety requirements. The leaching of heavy metals is strictly controlled within the international safety thresholds of lead ≤0.01mg/kg and cadmium ≤0.005mg/kg. For the molding and usage needs of different cookware types, such as woks, soup pots, and rice cooker inner pots, we customize and optimize the composition ratio of the base material to ensure that the products have both excellent thermal conductivity and molding stability. They withstand 100 cycles of hot and cold heating at 420℃ without deformation or cracking.
Process innovation is our core competitiveness. We employ cold continuous rolling combined with precision annealing, using an online laser thickness gauge for real-time monitoring to control the thickness tolerance of aluminum discs to ±0.01mm and flatness ≤10μm, providing an excellent foundation for subsequent deep drawing. Our unique grain refinement technology results in an elongation rate ≥30% and a cupping value of 8-10mm, preventing cracking and wrinkling during deep drawing and significantly improving customer production pass rates. Our fully clean production process achieves zero oil stains and zero scratches, with a surface roughness Ra≤0.8μm, allowing for direct adaptation to non-stick coatings and other subsequent processing.
A rigorous performance verification system ensures stable product quality. Each batch of aluminum circles products undergoes salt spray testing (corrosion resistance time ≥500h), thermal conductivity testing (thermal conductivity ≥200W/m·K), and mechanical property testing, with key indicators exceeding international industry standards. Thanks to its superior quality, we have become a long-term supplier for numerous well-known kitchenware brands in Southeast Asia, Europe, and Latin America, providing them with specialized aluminum circles for pots, woks, saucepans, frying pans, etc., with an annual supply exceeding 5,000 tons. Addressing the stringent safety and performance requirements of European customers for kitchenware substrates, we have customized and optimized our production processes. Our cookware aluminum circles products have passed authoritative international testing and certifications such as SGS and BV, successfully helping customers enter the high-end kitchenware market, with excellent market feedback. For the large-scale production needs of Southeast Asian customers, we have optimized capacity matching and delivery processes to ensure efficient order fulfillment, earning the long-term trust of our clients.
Haomei Aluminum is rooted in technology and committed to quality, continuously providing the global kitchenware industry with superior aluminum circles substrate solutions. We possess flexible customized production capabilities, precisely matching materials, specifications, and performance parameters according to customer needs, helping customers create more competitive kitchenware products.
