Liquid Penetrant Inspection (LPI)

Liquid penetrant inspection (LPI) is also called as dye penetrant inspection (DPI), or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface defects on metal castings, such as small cracks, porosity and shrinkage. Visual inspection can not find these tiny defects, but those defects may seriously affect the pressure-bearing casting parts. Our foundry is using this inspection method for grey and ductile iron casting products.
