April 1995 Bulletin
(modified in 2002 to include
ThermaLLifeÒ)
Everyday we are asked - What steps should I take to prepare the tool so that tool life and performance is maximized? In response to this we have prepared a flow chart
that is beneficial to first time customers who are preparing their tooling for the MetaLL ifeÒ
and/or
ThermaLLifeÒ
process. This, in conjunction with
NADCA's published "E-501Die
Care Maintenance Manual", will assist every die caster to obtain performance and
extended tool life than was not possible 15 years ago (before the benefits of compressive stress were
confirmed and studied.).

Sometimes we are queried about the effect of polishing a die after MetaLL ifeÒ to remove some of the topography. This is especially common for zinc dies where a hardware finish is
required. Polishing does not reduce the compressive stress benefit but rather adds slightly to it. Removal of all of the topography, however, will
affect the increased lubricity and flow benefits which some die casters, such as
magnesium, desire or need.
