GEO Pear-shaped wax casting sprues – Prevents shrink-holes in the cast metal

Function & Performance
Casting sprue with pear-shaped melting reservoir.

Advantages

  • Pear-shape for an optimal flow of molten metal.
  • The melting reservoir ensures controlled cooling.
  • Cavity-free and accurately fitting cast objects.

Tip:
The pear shape of the casting sprue is ideal as a melting reservoir. The large surface area of the attachment allows controlled cooling. The molten liquid in the casting object solidifies first, contracting and drawing the still molten metal out of the pear. This prevents bottlenecks from forming and blocking the flow. Shrinkholes and imprecise fits are thus prevented. (Burns without residue)
