Die (in metal manufacturing) (fr: Matrice – dans la fabrication de métaux): A specialized manufacturing tool used to cut or shape metal materials mostly using a press. Dies are usually customized to the item they are used to create. Different dies are used in different metal manufacturing processes like: blanking, broaching, bulging, curling, coining, drawing, roll forming and many more.

Die Casting (fr: Moulage sous pression): The process of casting a non-ferrous metal (usually aluminium or zinc) into a closed steel die either by pouring (gravity die casting) or injection under pressure (pressure die casting). Die casting is more accurate and faster than sand casting.

DOM steel tube (fr: Tube en acier DOM): A welded round steel tube with the internal weld seam removed thus creating a smooth internal surface. DOM Round Steel Tube has been drawn over a mandrel to form a tube with more exact dimensional accuracy and resistance, and a very smooth inside and outside finishes. DOM Round Steel Tube is ideal for stressful applications that require a higher quality, increased mechanical properties, strength, uniformity and soundness.

Drawing (Metal) (fr: Etirage): The operation of drawing metal through a die to produce long lengths of tube, wire, or strip sections.

Drilling (of metal) (fr: Forage – des métaux): The process of cutting holes into metal by using a rotary cutting tool – the drill bit. Unlike punching metal, drilling cuts the material while spinning and thus, the waste ejects up through the hollow shaft and exits through the top.

Ductility (fr: Ductilité): The ability of a material to deform plastically without fissure. This ability is measured by elongation or reduction of area in a tensile test.
