The SPAG-LESS system is a special type of mould drying, to remove absorbed water.
This mould drying system does not use heat but compressed air, which is fed through a series of channels into the plaster mould.
These channels are all connected each other and finally to one or more headers which will be connected to the source of compressed air. The result is a series of regular cylindrical cavities that arrive from the rear of the mould up to about 1.5 to 2 cm from the casting surface of the mould.
As a result, using this technique, it is possible to work on three continuous shifts, even with two/three casting operations per shift.
