The standard auger is formed in a special winding machine that transforms a steel strip into a continuous one-piece spiral, with the desired diameter, pitch and thickness to fit the shaft. It is subject to a cold lamination process that does not affect the mechanical characteristics of the material.
The spiral (1) has a conical cross section, where the inner thickness is approximately twice as thick as the outer size.
It is currently the most convenient auger series on the market and at Sinfines Factory, in order to provide quick delivery to our customers, we always have a large stock of the following measures, as listed in the table, with and without shaft.
