The below photos
show processing of o-ring and/or seal grooves
on
the ejector side of critical dies whose components
provide sealing when
matched together. Sometimes the cover side of the die has
the sealing groove. Since stress risers occur on both the raised or
grooved
side of the sealing area, it is recommended to MetaLLifeÒ
process both halves.
Processing of only the
standing o-ring groove of
front engine cover.
Customer for this application was concerned
about heat checking for the entire casting surface.
Had tried welding previously without success.
O-rings or sealing material can be damaged if casting risers exist in these
areas.
