Annex I:
Correct Sprueing

As common to any casting system some device dependent and physical
properties have to be obeyed to obtain satisfactory results.

The Waxdisk

The waxdisk of the

Cast

– system replaces the sprue base known from other

casting systems.
In common casting systems objects are sprued to a central sprue base acting
as a bottleneck for the metal flow. Using the

Cast

– system objects are sprued

radially to the waxdisk resulting in a higher flow rate for each single sprue.

Fixing of Sprues to the Waxdisk

The sprues are to be fixed radially around the widest extent of the waxdisk with
wax as depicted in the illustration below. Care has to be taken that the sprues

are fixed with their full intersection along the waxdisk – otherwise the effective
diameter for metal flow will be reduced resulting in a delayed or insufficient
filling of the mould or miscasts.
