- the textured surface is created on the necking and expansion dies via peening with precision ball bearings to create a smooth, but dimpled, texture.
- Peening comprises thrusting precision balls with hardness greater than the die to create dimples in the tool surface.

- a precision ball is a ball having a diameter that varies by no more than about 1%
- a tool surface that is smooth, but not flat, is able to reduce friction without excessive debris generation or tool wear.
- the reduced friction is due to reduced area of contact between the die and the metal container. Contact area is as characterized by WinSam (Surface Analysis Module for Windows) as described in ("Surface Characterisation in Forming Processes by Functional 3D Parameters,", S. Weidel, U. Engel, Int. J. Adv. Manuf. Technol. (2007) 33: 130- 136), which is incorporated herein by reference.
- the reduced friction enables metal containers to be expanded or narrowed to a greater degree in a single stroke of an expansion die or a necking die without damaging the container. Damage includes wrinkling, fracturing, ludering, collapse of the metal container or anything that diminishes the appearance of the metal container.
- Some embodiments of this invention look at topography of the textured surface using 3 -dimensional surface parameters and aim to minimize the area of contact of the tool with the work-piece.
- use of a textured surface on an expansion or necking die may have any combination of the following advantages: maximizing the extent of metal forming in a single stroke of an expansion or necking die without damaging the container due to decrease in friction, thus reducing the number of metal forming steps and reducing the amount of scrap; reducing the starting weight required to meet final product dimension specifications; eliminating the need to use lubricant when forming the metal containers.
- peening a die with precision balls results in a die that can form a metal container without defects more consistently than a highly polished die.
