After cutting the sprue and riser of the 1200 * 1000 * 60mm base trays, small pores were found to accumulate, and there were suspected crack defects nearby. A destructive test was immediately conducted on it, and the internal grain structure was loose, with some shrinkage and aggregation. The base trays of the batch was temporarily sealed. Read More

At the request of the customer, the interior of the casting was inspected for defects. A cast grid 600 * 500 * 50 was randomly cut, and its grain structure was compact with no obvious defects in the cross-section, meeting the customer's requirements. Read More

The size of the casting tray is 1000 * 600 * 50. During the incoming inspection, it was found that multiple side ribs of the tray had suspected crack defects. PT testing in this area showed light imaging. On site, it was decided to cut one of the pieces, and the cutting section was flat without any crack defects. It was determined that this area is acceptable as non defective. Read More

Both visual inspection and PT testing of the casting grate revealed varying degrees of cracks. On site, it was decided to cut the crack area, but the cutting section was not satisfactory. The cracks extended into the grate, and severe cracks could penetrate the entire section. Determine as a crack defect and reject the batch of products from storage. Research has found that there are designed sprues and risers in this area, and the number and design positions of sprues and risers will be optimized in subsequent production to avoid such problems.
