This type of mould is designed for ceramics that are produced in very considerable numbers. The moulds are complex with a structure of three casings. Unlike the TM-EF moulds these have two rows of brake elements which enable the clay exit to be regulated with greater precision and without interrupting the production process.

The first casing secures the mould to the extrusion nozzle and receives and compresses the clay. The first row of brakes is screwed to this casing.

The second casing carries out two important functions; on one hand it serves to secure the grate and on the other it has groves through which the second row of brake elements enter and exit.

Another advantage is that being able to dispense with welding it is possible to use more resistant materials in the manufacture that were previously impossible to contemplate.

With these brakes it is possible to regulate better the quantity of clay necessary for the piece to exit perfectly. One great advantage of this type of mould is precisely the grate in which, unlike for the other moulds, the platens are not welded to one another, but consist of individual pieces that fit into the groves where they are screwed down. With this system, invented and patented by Talleres Morte e Hijos, great stability in the extrusion walls is obtained and the change of pieces is greatly facilitated.

The third casing is the same as the plate on conventional moulds. The serrations and blades which shape the brick are screwed down here.

This type of mould is recommended for manufacturing numerous bricks, whether horizontal or upright.
