Non Destructive Testing (NDT) - Liquid Dye Penetrant and Magnetic Particle Inspection

Electromold Australia has the ability to complete Liquid Penetrant Non Destructive Testing (NDT) to determine any fractures, cracks or fatigue in our customer's parts prior to completing processing or as one off service.

Non Destructive Testing or NDT is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or systems without causing damage. The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.  Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic and eddy-current testing. NDT is commonly used in aeronautical engineering, mechanical engineering, forensic engineering, electrical engineering, civil engineering and systems engineering.

Electromold  has NDT capability and provides NDT techniques using Liquid Dye Penetrant and Magnetic Particle Inspection.  Electromold has a purpose NDT Laboratory that provides both Liquid Dye Penetrant inspection and a 2.7metre Magnetic Particle Inspection bench along with portable magnetic particle inspection units.  Our Liquid Dye Penetrant facility can handle parts up to 1.5 metres in length.

Our NDT Processes are NADCAP and NAS-410 approved.  They are also approved by Lockheed Martin and The Boeing Company.  We have many years' experience in providing these two NDT services with our NDT Inspectors being amongst the highest qualified in the Southern Hemisphere.

Liquid Dye penetrant inspection (DPI), also called liquid penetrant inspection (LPI) or penetrant testing (PT), is a widely applied and low-cost inspection method used to locate surface-breaking defects in all non-porous materials (metals, plastics, or ceramics). The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.

Magnetic particle Inspection (MPI) is a non-destructive testing (NDT) process for detecting surface and slightly subsurface discontinuities in ferroelectric materials such as steel ,nickel, cobalt, and some of their alloys.

The Dye penetrant test (DPT) based on liquid penetrant is a sensitive extremely versatile and a very reliable method of test.

Some of the applications for our NDT Service:

  • Fracture critical parts
  • Fatigue
  • Weld Inspection
  • Post Machining
