Liquid penetrant testing

Non-Destructive Testing

Non-Destructive testing by penetrating liquid (PT) is one of the most traditional method of analysis used in automotive industry to detect the surface breaking defect on any non- porous material.
The CND method with penetrating liquid allows to detect, rapidly and reliably, the breaking open on surface (like cracks, porosities, folds, sprains, cracks due to effort and heat treatment) on any type of component, independently of geometry or type of material.
Penetrating liquids are sophisticated products today, which, based on their physical-chemical features, determine the inspection technique and equipment to use. For this reason, Punto Netto has got the best products for this inspection and the mobile equipment to perform the activities at plants, to avoid costs due to the handling of goods.
