The spag-less system is a special type of mould drying to remove absorbed water. This system does not use heat, but compressed air introduced through a series of channels inside the plaster mould.
Regardless of the technique used to create a venous network inside the mould, the injection of compressed air allows you to quickly remove the water absorbed by the plaster during the casting phase.
This process also allows a reduced residence time of the water in the mould, helping to increase its duration.
