Inspection possible for both metallic and non-metallic materials! Introducing penetrant testing with high flaw detection capability.
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 it is also capable of inspecting aluminum and stainless steel, which cannot be tested using 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 by magnetic particle testing ■ Magnified detection capability compared to actual defects ■ Easy to perceive due to the contrast between the penetrant and developer ■ Excellent detection capability for narrow and deep defects ■ No direction dependence for detectable defects *For more details, please refer to the related links or feel free to contact us.

basic information
【Principle】 ■ Penetration Treatment - Apply the penetrant to the surface of the test specimen. - The penetrant seeps into the internal flaws due to capillary action. ■ Removal Treatment - Remove the excess penetrant from the surface of the test specimen. ■ Development Treatment - Form a developer film (white fine powder) on the surface of the test specimen. - The penetrant inside the flaws is drawn out due to capillary action. *For more details, please refer to the related links or feel free to contact us.
