Crack detection systems for the highest quality requirements.

Sophisticated crack detection technology — because safety knows no compromise

Non-des­truc­ti­ve crack detec­tion plays an important role as a qua­li­ty assu­rance tool, par­ti­cu­lar­ly for safe­ty-rele­vant and cost-inten­si­ve com­pon­ents. We crea­te safe­ty at this point with our manu­al, semi-auto­ma­tic and ful­ly auto­ma­tic sys­tems. The­se work accor­ding to the prin­ci­ple of the pene­trant method, one of the most wide­ly used crack test­ing methods in the field of non-des­truc­ti­ve mate­ri­al test­ing.

We are also hap­py to manu­fac­tu­re pro­cess com­bi­na­ti­ons for you accor­ding to your requi­re­ments, such as pick­ling or clea­ning with down­stream crack detec­tion. Just like the rest of our pro­duc­tion pro­gram, our crack detec­tion sys­tems are tail­o­red to the indi­vi­du­al needs of each cus­to­mer.

You recei­ve ever­y­thing from a sin­gle source: from design and pro­duc­tion to assem­bly, inclu­ding auto­ma­ti­on — exact­ly as you need it!

Non-des­truc­ti­ve crack test­ing using the pene­trant method

The pro­cess, which is based on the phy­si­cal law of capil­la­ry action, is uni­ver­sal­ly appli­ca­ble and can be used regard­less of the mate­ri­al in ques­ti­on.

    The mate­ri­als are fed to the test in their initi­al sta­te.

    It must be ensu­red that the mate­ri­als to be inspec­ted and any cracks in them are clean and dry. If neces­sa­ry, the mate­ri­als are pre-clea­ned at this point.

    The pene­trant is then appli­ed by dip­ping or spray­ing and must then be left to work for a suf­fi­ci­ent­ly long time.

    During inter­me­dia­te clea­ning, the agent is remo­ved from the sur­face, but not from the cracks. In the emul­si­fy­ing pro­cess, the emul­si­fier is now appli­ed and also only remo­ved from the sur­face. This lea­ves the resi­due of the agent in the cracks.

    After dry­ing, a deve­lo­per is appli­ed, which pulls the remai­ning pene­trant out of the cracks like a blot­ting paper. Depen­ding on the pene­trant used, the defects beco­me visi­ble eit­her direct­ly or under UV light.
