Sprue casting wax with reservoir

Casting Sprue are wax that is used to connect the wax model with the casting mold’s opening.

During burnout, the wax is eliminated to leave channels through which molten metal flows into the mold cavity.

Using a Casting Sprue with Reservoir prevents localized shrinkage porosity.

The Reservoir is a piece of wax attached to the sprue former approximately 1 mm from the wax pattern.
