Permanent quality control for each step of the manufacturing.
During each step a control is realized on the parts by the operator (shearing, forging, trimming, turning…) and at the end of the manufacturing, the parts are tested in our internal laboratory to check there are conformed to EN 14399 parts 1-2-3-6.
For these tests, UTN used 3 machines :
- The test bench for fitness for purpose to control the tightening torque of the bolt. It must be respected during the setting.
- The tensile test bench clenches on the bolt a torque that could go until the break of the bolt this test allow to mesure the hardress limit of the bolt.
- Charpy drop hammer, as to it, allows to calculate the maximal energy the bolt can resist before break.
