The quality of the nylon tie toothed belt and the head cavity

The key parts of the nylon tie are the quality of the toothed belt and the head cavity, which is crucial. Therefore, the toothed belt should be carefully observed and there should be no residual teeth. There should be no step like mold deviation marks on the top of the inner surface of the cavity, otherwise a large number of unusable sliding teeth will appear, making it difficult to insert, almost equivalent to waste and unusable.

These issues require careful attention, just like the simple phenomenon of edge cutting. If the edge cutting is too large, the tooth surface of the inserted belt and the head cavity will not fit tightly, and it is easy for the teeth to loosen and slip.
