sheetmetal. The two processes of making the metalbase for the lamp is sheet metal forming or die casting. The material that themetal base is made out of is a zinc alloy because its properties are that itshigh strength are hardness, this means its more cost effective and will bebetter for mass production. Sheet metal forming is formed into flat pieces that are used in metal workingand can be bent into a variety of shapes.

Ceramic manufacture impact on designBiscuitis any pottery after the first firing and before any glaze is applied.
