As part of the complete package, Tech-Max uses a variety of non destructive testing procedures (both in-house and outsourced) to ensure that the materials used to make your parts meet your quality expectations. These non destructive examinations verify the material’s surface and internal integrity. When combined with our stringent dimensional tolerance inspections, these examinations round off a complete inspection package that ensure quality parts across different disciplines.
A non-destructive method for determining the existence and extent of possible defects. A specially formulated liquid called penetrant is applied to the material surface where it seeps into any infraction, void or crack. The penetrant is then wiped clean and a developer is applied. Wherever the penetrant is found, it will appear as a red indication over the powdery white developer and clearly define the infraction. This “first line of defense” test works on all materials regardless of the composition and is generally considered an easy way to double check the surface integrity of your material. It also works on stainless steel and other nonferrous alloys where the magnetic particle inspection is not applicable.
A non-destructive method for determining the existence and extent of possible defects in ferromagnetic materials. The material or part being inspected is magnetized. Finely divided magnetic particles, applied to the magnetized part are attracted to and outline the pattern of any magnetic-leakage fields created by discontinuities, cracks, voids or flaws. The ferromagnetic requirement limits this method to carbon and low-alloy steels rendering it useless on stainless steels and other nonferrous alloys.
A non-destructive method for determining the existence and extent of possible defects within materials. When acoustic energy in the ultrasonic range is passed through steel, the sound waves tend to travel in straight lines. If there is a defect in the path of the beam, it will cause a reflection of some energy. This casts an acoustic shadow which can be monitored by a detector to show the size and depth of a deeply embedded defect.
A non-destructive method for determining the existence and extent of possible defects. X-Ray instruments use penetrating x-rays or gamma radiation to capture images of the internal structure of a part. This inspection is performed by qualified subcontractors that perform the inspection both in the laboratory and on-site.
