Course:SPPH381B/Essays/TermProject/Aluminum Foil - Soham/Thinning Aluminum Sheets

Introduction

In order to be ready for packaging, aluminum retrieved from primary manufacturing is rolled in a rolling mill. The aluminum is passed through rolls (made of metal) in order to be squeezed and thinned. This is accomplished with the help of another set of heavy rolls known as backup rolls, which help to apply pressure evenly across the aluminum. Lubricant and heat-treating is used concurrently with this process by manufacturers to ensure quality.

Foil thickness is controlled by modulating the rotation speeds of the rolls as well as the fluid dynamics (viscosity) and temperature of lubricating agents. After being flattened by the rollers, the aluminum product may be cut with circular or razor-shaped knives on the edges to produce several sheets. The final product may be treated with various chemicals or heat-sealants depending on final usage.
