2) During processing: heat treatment tests.
These are hot pre-tests that guarantee the performance required to the machine.
3) After final assembly: process repeatability tests after set-up, so that there is total safety on the actual operation of the machine.
In the unlikely event of a non-alignment between request and results, the commitment of Hi-Tech engineering is to analyse the problem, find the solution and repeat the test, which will hardly recur the issue found-out in the first step.
