Die Casting & Foundry
Technology
ASTON and our associates have extensive experience
with foundry and die casting materials. We analyze die steels to
assist with troubleshooting premature failures as well as monitor
routine heat treating and quality issues. H13 die steels are
evaluated to NADCA specifications for chemistry, hardness, grain
size, homogeneity and heat treat response.
Routine testing as well
as failure investigations are performed on aluminum, zinc and magnesium
die castings as well iron and other foundry materials. Chemical
composition, gas and shrinkage porosity, cold flow, fill, sludge, inclusions,
dendritic patterning, graphite flake/nodule morphology, carbide content, ferrite/pearlite
may be analyzed in the castings.
We go beyond the routine to help our clients
identify problems. We used
this special etchant to reveal intergranular carbides found in this inferior
die steel. Our client might otherwise have purchased the cheaper material
and suffered the consequences of premature failure.
