Traditional punches

A punch with a simple design, its depth varies from 1.6:2 mm and filled with resin that varies in thickness from 0.6:1 mm.

Isostatic punches

The isostatic punch equalizes the pressure on all of its points, avoiding wasted time in cleaning the grids and variation in size, suitable for pressing any kind of tiles especially medium and large sizes as it has high compensation, its types are:
