Abstract

The subject of the present invention is to provide a crack detection method for cassette bowl. The crack dele to. To solve the problem, the present invention provides a crack detection method for cassette bowel. After an opening part of the cassette bowel 4 that has recycled powders in a previous step faces downward, a support plate 12 for supporting the negative pressure space forming means 1 is made to be upward, so that a mask 3 that receives the cassette bowel 4 tightly contacts the front surface of the support plate 12. Then, the internal pressure reduction status of the negative pressure space forming means 1 is made to eject air via a nozzle arranged in the negative pressure space forming means from a lower side to the inside of the cassette bowel, so as to remove the powders attached on the inside of the cassette bowel. At the same time, the internal pressure of the mask 3 is measured, so as to detect whether there are cracks on the cassette bowel 4 or not based on the variation of the internal pressure.
