How to make aluminum coil?

To make aluminum coil, start with high-quality aluminum ingots. These are melted in a furnace and then poured into a casting machine to create a continuous cast strip. This strip is passed through a series of rollers to reduce its thickness and achieve the desired width and thickness. The rollers apply heat and pressure, gradually forming the aluminum into a coil. The coil is then cooled, often using water, and wound onto a mandrel for storage or further processing. Quality control checks are performed throughout the process to ensure the coil meets specific strength, thickness, and surface finish requirements. The final product is a tightly wound aluminum coil ready for use in various industries such as construction, automotive, and packaging.
