Its main functions include eliminating the yield plateau, enhancing coating adhesion, improving strip flatness, and providing optimal substrate conditions for subsequent processes such as color coating. The equipment is positioned between the post-plating cooling and drying unit and the tension leveller, enabling precise control of the strip's surface condition and mechanical properties through accurate adjustments to rolling force, elongation, and bending roll settings.
As market demands for strip quality continue to rise, most galvanizing lines are now equipped with skin-pass mills. These machines serve to enhance the surface finish of the strip while reducing or eliminating the yield plateau, ultimately improving the material's mechanical properties. Our company can design and manufacture skin-pass mill equipment in various specifications to meet the unique needs of different customers.

Aluminum alloy casting is a manufacturing process that involves pouring molten aluminum alloy into a mold, allowing it to cool and solidify into the desired part shape. It is widely used in industries such as automotive and aerospace. The main casting methods include sand casting, metal die casting, die casting, and low-pressure casting, each suited to different levels of complexity and production volumes—for instance, sand casting is ideal for large components, while die casting enables high-precision, high-volume production.
