230 Casting System Model casting Stand 1.9. 03 A 18

Sprue/sprue former

All model castings are cast from the top.

Sprue formers for model casting

Plastic sprue cones should be used.

Note! Do not use other cone shapes than recommended.

The shape of the sprue cone and the position of the sprue

channel help the melt to flow cleanly. The funnel must be

in the center of the casting ring, so that the muffle can be

centered cleanly in the unit.

Attention! The new funnels are equipped with cavity

formers for better aligning of the packing rings.

A Correct positioning, B+CIncorrect positioning.

Not centered (B) or inclined sprue cone positions (C)

adversely affect the way the melt flows into the hollow

cavity of the casting.

C Reduced seal coverage and uneven pressure on the

muffle.

Positioning of funnel former

Wax up funnel with bottom edge at occlusion level.

The investment must be filled to the top edge of the funnel

former. Avoid air bubbles at the fitting surface.
