Inspection Testing in Foundries topics include: Inspection and testing, inspection procedures, visual and dimensional inspection, mechanical properties testing, destructive and non destructive testing. Foundries use a variety of inspection and testing methods: Visual inspection: Uses the human eye to identify surface defects, such as cracks, tears, misruns, molding flaws, and cold shuts. Liquid dye penetrant inspection (LPI): Uses a colored dye in an oil solution to find tiny cracks, pores, or other surface imperfections in metal castings. Magnetic particle inspection (MPI): Uses fine... Show more

Foundries use a variety of inspection and testing methods:

Visual inspection: Uses the human eye to identify surface defects, such as cracks, tears, misruns, molding flaws, and cold shuts.
Liquid dye penetrant inspection (LPI): Uses a colored dye in an oil solution to find tiny cracks, pores, or other surface imperfections in metal castings.
Magnetic particle inspection (MPI): Uses fine iron filings or particles to detect surface and near-surface flaws in investment castings made of ferromagnetic metals.
Radiographic inspection: Uses X-rays or gamma energy to pass ionizing radiation through a casting to reveal internal discontinuities on a film medium.
Ultrasonic inspection: Uses high frequency sound energy to detect the presence of inherited discontinuities.
Eddy current inspection: Can detect minor cracks and defects near the surface.
Tensile strength test: Measures the casting's potential to resist tension and provides insights into its mechanical characteristics.
