Complex internal features such as swept bends can be formed by the use of soluble cores (orange wax). Tolerances however may require relaxing.
Tooling for a complex component can sometimes be simplified by joining two or more patterns together at the wax stage. This enables the requirement for brazing after casting to be eliminated.
Cast Gears and Teeth
Components requiring teeth for gripping or gear applications may be impossible to produce by machining. The definition achieved by the Sylatech process is ideal for these applications.
Integrally cast rivets can be peened over to give an economic, strong and permanent joint.
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: 0.25mm - 0.5mm (0.010" - 0.020")
