The pear is the ideal shape to create a thermal centre.
Targeted and uniform cooling.
The melt reserve remains liquid for a longer period of time and until the final solidification the additional suction of the melt is guaranteed.
The dowel is fixed directly to the casting object, eliminating the gorge between the object and the casting reservoir, which would solidify too quickly in the conventional method.
Avoids cavities formed in the shrinking process and porosities.
The casting result can be further improved by limiting the casting to the pin and the object.
