Drawing is the process by which the semolina and water mixture is passed by extrusion (or compression) through a shape called “matrix” or “die”, with holes of different shapes and sizes that reproduce the desired pasta format . Subsequently, a series of rotating knives placed at the exit of the “matrix” cut the product, determining the length of the format. The material with which the “matrices” are made defines the porosity and structure of the external surface of the dough. In Italy, dry pasta is obtained through the particular Italian technique of bronze drawing, from the rolling and consequent drying of doughs prepared with durum wheat semolina.

This involves a big difference between industrially processed pasta and bronze pasta.
Manufacturers of industrial pasta have abandoned this traditional bronze drawing method, preferring the one with Teflon dies, which are smoother and less stressful for pasta.
This choice, however, is mainly dictated by the request for a higher production speed. Furthermore, this type of processing is made necessary due to the use of low quality semolina which would not be able to tolerate bronze dies.
