Vemek’s nail coolers for foundries consist of a soft iron body and a welded anchoring nail which, being perfectly pointed, allows easy and reliable positioning. When correctly positioned at the centre of the fluid mass to be cooled, they absorb part of the heat and speed up solidification, eliminating shrinking cracks and porosity during solidification. The sizes and shape of the body and nail can be modified as required. The ringed shape is preferable to obtain perfect fusion.

Coolers for foundry are the ideal solution for problems of blowholes caused by shrinkage. Working with coolers means finding the perfect balance between the cooler casting (joining with the casting) and its ability to cool the casting from the inside.

It is essential to identify the most suitable type and mass for your casting. The form is also adaptable to avoid possible interference in subsequent processes.
