Casting Sprues "EM"

REF 02-1910_M

CASTING SPRUES WITH RESERVOIR

Most ideal shape of flow resulting in a more homogeneous casting structure without cavities or shrinkholes. The al dente casting sprues “EM” with a sprue’s head diametre of 6–7–8 mm are used for precious metal alloys. al dente casting sprues “NEM” with a sprue’s head diametre of 7–8–9 mm and an increased cross-section of the sprue are especially used for vacuum pressure castings, non-precious alloys and precious-metal reduced alloys.

ADVANTAGES
- Reshaping of the ball to its technically most ideal shape of flow: the nozzle. This shape has the advantage that the alloy being injected swirls less.
- Due to the tube diameter of 3 mm and the concave shape of the reservoir, an easy and metal-saving removal after casting is provided.
- A more homogenous texture without cavities is the result.
- Easiest waxing of the sticks by soaking the waxing stick. Aperture diameter of 3 mm and the concave shape of the reservoir on the waxing side assure good accessibility and thus enable metal economy and easy removal after casting.
