referred to as u201c necking force u201d it has unexpectedly been determined that a necking surface having a textured surface provides less resistance to a bottle stock being necked than a non textured surface as opposed to the prior expectation that a smooth non textured highly polished surface would provide less resistance and hence require less necking force it has been determined that a surface with a relatively low ra value i e lt u02dc 6 micro inches has greater surface contact with the bottle being necked resulting in greater resistance and requiring greater necking force in some embodiments of the present invention the increased surface roughness higher ra value reduces the surface contact between the necking surface and the bottle being necked hence reducing the required necking force reducing the necking force required to neck the bottle stock allows for necking dies having a greater percent reduction than previously available in prior necking dies it also helps to enable the die to neck through varying thicknesses of metal sidewall in one embodiment a textured surface has a surface roughness average ra ranging from more than or equal to 8 u03bcin to less than or equal to 32 u03bcin so long as the textured necking surface does not disadvantageously disrupt the aesthetic features of the bottle stock 39 s surface coating finish in a significantly observable manner in one embodiment a non textured surface has a surface roughness average ra finish ranging from 2 u03bcin to 6 u03bcin fig3 represents a surface mapping of one embodiment of a non textured land portion 13 of the necking die generated by ade phase shift analysis and mapvue ex surface mapping software in this example the.
