All dies are tested before the beginning of the extrusion process.
The shape and dimension of the extruded profiles are regularly checked during the extrusion process. All the relevant parameters are recorded in order to ensure product uniformity.
Tests are also performed after the profiles aging process, including the testing of mechanical properties. The tensile tests and hardness tests are used to check if the values correspond to the values stipulated within the EN standards.
In the case of mechanical processing, profile dimensions are checked so as to match the required drawings.
If profile surface treatments are applied, a series of tests are performed in order to maintain the quotas as per the drawing which was requested by the customer.
