A good sewing method is crucial to the quality of the bouncy castle, otherwise the bouncy castle will be torn. Today we will discuss this topic.

The traditional sewing method is to sew on the reverse side of the material, so that the traces of sewing cannot be seen on our bouncy castle, which can make it look more beautiful. But we can see from the video below that this sewing method is easy to cause tearing, so now we have improved the sewing method.

The sewing method from East-inflatables has been improved. We did two reinforcement stitches from the face of the material, and used carriage returns at the beginning and end of the stitching, which made the corners stronger. We did the same experiment, and this time you couldn’t tear it no matter how hard you tried.

In addition, the stitch length is also very important. A good stitch distance should be controlled at 5-6 stitches per inch, and the gold stitch distance of PVC fabrics should be 2~3 stitches per centimeter, that is, the stitch distance should be controlled between 4.2-4.5MM, not too small, or Can not be too large. Otherwise, there will be fabric partitions, large air leakage, etc.!
