Products & Services
penetrant flaw detector
Eishin Chemical accepts requests for manufacturing various flaw detectors. We hope that you will find it useful for improving quality control and efficiency.
Introduction of demo machine
At our Ibaraki factory, we have a demonstration machine that can handle many conditions.
It can be used for consideration of equipment introduction and consultation on flaw detection conditions.
Type of flaw detector
- Washable fluorescent penetrant flaw detector
- Washable Dye Penetrant Flaw Detector
- Post-emulsifying fluorescent penetrant flaw detector
- Pretreatment equipment (equipment for cleaning inspection objects before penetrant testing)
- flush booth
- Heating and pressurizing device (for washing booth)
- Dryer (hot air circulation type)
- Development booth (closed type for dry development, dust collection type for quick dry development, etc.)
- Dark room (for observation of fluorescent penetrant testing)
- Wastewater treatment equipment
- In addition, inspection equipment optimized for penetrant flaw detection and related parts (conveyance mechanism, jig, etc.)
A magnetic particle flaw detector that facilitates magnetic particle inspection
By using the portable magnetic particle flaw detector "Handy Magna", magnetic particle inspection can be performed most easily. It is compact and lightweight, making it ideal for on-site inspections.
Features of Handy Magna
- Since it is AC magnetized, it has excellent ability to detect surface defects due to the skin effect.
- A-1 and A-4 have a wide magnetic field effective range, and A-2 and A-6 are compact and lightweight, making them convenient for long-term flaw detection.
- HM-76 and TE-2 are especially small and lightweight, so they are suitable for small parts, local inspection, and flaw detection inside parts.
- HM-76 can detect flaws on the inner side of an inner dimension of about 160 mm square.
- The HM-52L has right-angled magnetic poles, so it is effective for fillet flaw detection. It is possible to detect flaws in the inner fillet of a recess with a frontage of up to about 100 mm.
- By using a variable yoke, it is easy to detect flaws on uneven parts, R surfaces, corners, etc.
- It is compact, lightweight, and uses a 100V power supply, making it ideal for portable use.
- There is no worry about sparks because the current is not applied directly to the object to be inspected by the inter-electrode method.
- The A-1, A-2, A-6, HM-76, and HM-52L have a direct connection between the main unit and the cable, so they are strong and waterproof.
