The canal cooling plates are produced through the inflation of two metal sheets, which have been laser-welded among themselves, in order to get an inner canalization, bringing the fluid in contact with the whole surface of the plate.
Additionally, between the shells of the cooling plate is made a perimetral weld, through a TIG Process, for the purpose of guaranteeing a greater cleanliness between the sheets. This avoids chemical or bacterial attacks.
More specifically, the TIG welding is one of the most widespread methods, which guarantees a very high quality joint, thanks to the arc-weld with a tungsten electrode under the protection of noble gas.
The thicknesses of metal sheets that compose the cooling plate measure 1+1mm until the length of 3000mm and 1,2+1,2mm for the higher dimensions. The finish is made electrochemically, in order to obtain a polishing, which allows the cleansing for the easy removal of tartaric acid and other similar agents. The cooling plates are available both in AISI304 and in AISI316, according to the dimensions in the chart below.
