Haomei Aluminum

  Haomei Aluminum's DDQ (Deep Drawing Quality) aluminum circles for cookware are premium deep-drawing substrates engineered for the mass production of cookware requiring high draw ratios. Leveraging comprehensive process control based on DC (Direct Chill) semi-continuous casting, DDQ aluminum circles offer significant upgrades in forming limits, batch consistency, and surface density. They specifically address industry pain points—such as fluctuating yields and post-forming surface defects common with standard deep-drawing materials—and meet the large-scale production demands of high-end, deep-drawn cookware. The core quality advantage of these DDQ aluminum circle for cookware lies in their superior forming capabilities and consistent performance. Manufactured from large-format DC cast ingots, the material undergoes homogenization annealing at a constant 480°C for over 12 hours to completely eliminate compositional segregation and internal casting stre...
