Penetrant testing

Introduction of a testing method utilizing capillary action when the infiltrating liquid seeps out of the wound.

The "penetrant testing" is a suitable method for detecting surface-opening defects in test specimens. It utilizes the capillary phenomenon to allow liquid to penetrate, and when the penetrant is applied, it seeps into surface cracks and other opening defects. After that, the excess penetrant is removed by wiping with a removal solution or rinsing with water, and a developer (white fine powder) is applied to draw out the penetrant remaining in the opening defects, thereby forming an indication pattern (penetrant indication pattern). It is widely used for both metals and non-metals and excels in detecting surface-opening defects, which are considered the most harmful. 【Features】 - Detects surface-opening defects in test specimens - Utilizes the capillary phenomenon for liquid penetration - Forms indication patterns (penetrant indication patterns) - Widely used for metals (both magnetic and non-magnetic) and non-metals (such as ceramics) - Excellent in detecting surface-opening defects *For more details, please refer to the PDF document or feel free to contact us.

Penetrant testing

Inspection is possible for both metallic and non-metallic materials! Introducing the high sensitivity penetrant testing method for detecting flaws.

The "penetrant testing" is an inspection method that utilizes the capillary phenomenon of liquids to detect surface defects that are open to the material. It can be used to inspect both metallic and non-metallic materials, and can also inspect aluminum and stainless steel, which cannot be tested with magnetic particle testing. The defects are magnified compared to their actual size, providing high detection capability, and it excels in detecting narrow and deep defects. 【Features】 ■ Can detect surface-open defects ■ Applicable to both metallic and non-metallic materials (excluding porous materials) ■ Can inspect aluminum and stainless steel, which cannot be tested with magnetic particle testing ■ Magnified compared to actual defects, providing high detection capability ■ Easy to perceive due to the contrast between the penetrant and developer ■ Excellent in detecting narrow and deep defects ■ No directional dependence on detectable defects *For more details, please refer to the related links or feel free to contact us.

Penetrant testing

Penetrant testing suitable for inspecting small machine parts or partial inspections of large structures.

We conduct a "penetrant testing" where the penetrant that has seeped into the defects is drawn out by the developer, resulting in the formation of penetrant indication patterns for evaluation. It is excellent for detecting defects that are difficult to find with the naked eye on surfaces. Please feel free to contact us if you have any requests. 【Features】 ■ Excellent at detecting defects that are difficult to find with the naked eye on surfaces ■ Applicable to non-ferrous metals such as Ti, Al, Cu, etc., as well as plastic carbon fibers, which cannot be tested with magnetic particle testing ■ Suitable for inspection of small mechanical parts or partial inspection of large structures ■ By using a high-temperature penetrant, inspections up to approximately 200°C are possible ■ It is impossible to detect defects through coatings such as paint *For more details, please download the PDF or feel free to contact us.
