Non destructive controls :

 - Ultra-sounds
Ultrasounds are used to test the mechanical properties of the part (risks of shrinkage cavity, gas defaults…).

 - Magnetoscopy
Magnetoscopy reveals defaults that surface the part (ex. Fissures).

 - Liquid penetrant testing
When using a liquid penetrant, any surface default will be detected.

 - Waterproof control
Water pressure is applied to the part to detect any waterproof default.

Destructive controls :

 - Mechanical testing are used to determine mechanical properties of the part. These tests are performed on specimens taken from bars with cast parts.

•  Tensile test machine is used to control :


•  Resistance to rupture
•  Elasticity limits
•  Steel elongation


•  Resilience testing is used to test the toughness of the part.
