It is possible to include many types of permanent product identification which can eliminate further need for labelling. Logos and text may be produced with minimum cost if the design ensures that detail is in the line of draw of the wax from its die.
Ideally, cast labels should use raised lettering on the casting face (engraved into the wax tool). Where such information must be below a functional surface, it can be sited on a pad sunk into the cast face.
Preferred depth of engraving: 0.25 mm - 0.50 mm (0.010" - 0.020").
