The invention relates to a construction method for improved tracer ammunition production. There is provided a method of forming a component for a round, said method comprising the step of causing said component to be drawn through at least one floating die.

A method is used to manufacture a drawn tube having a hollow low interior for housing an axle shaft. The method includes the steps of placing a billet into a first die assembly and pressing the billet into the first die to producing a pre-formed billet. The method also includes the steps of moving the pre-formed billet from the first die assembly to a second die assembly and pressing the pre-formed billet into the second die assembly to produce an extruded tube. The method further includes the steps of moving the extruded tube from the second die assembly to a third die assembly and pressing the extruded tube into the third die assembly to further elongate the extruded tube and decrease the thickness of the wall of the extruded tube to of from about 3 to about 18 millimeters to produce the drawn tube having the yield strength of at least 750 MPa.

A secondary battery case manufacturing method of the present disclosure includes preparing a material, forming an impact formed product by performing impact forging on the material with a die and a punch, and obtaining a complete product by applying ironing on the impact formed product.

A method for producing a metal cylinder includes preparing a metal slug having a polished surface, and molding the metal slug into a cylinder by impact-pressing with the polished surface as a bottom.
