No Shrink Pink
Castaldo no shrink pink is a natural rubber product just like white label and gold label, but with the added advantage that no shrink pink eliminates shrinkage with wax patterns showing shrinkage rates of below 1.0% and as low as 0.0%.
This rubber is therefore an ideal choice for model makers who set there stones within the wax. Also a superb choice of material for reproducing filigree style patterns where thin areas of the pattern exist.
It should be obvious that there are many variables beyond our control involved in jewellery casting such as the diameter and length of the sprue, the type and temperature of the wax injection pressure, holding time and metal casting process which may all contribute to casting shrinkage.
