Why is there a phenomenon of screw teeth slipping?

When the phenomenon of thread slippage occurs, it can be repaired by using a wire thread insert.
The main reasons for the sliding teeth of the screw teeth are:
1. Improper storage or maintenance of machinery or molds leads to slippage of threaded teeth in internal threaded holes.
2. Improper use causes the threaded holes in the machine or the mold to slip, because some machines require frequent disassembly and installation;
Especially for mold products, maybe a mold needs to be replaced several times a day, and the installer is too careless, causing the internal threaded hole to be damaged.
3. Due to environmental factors, the environment where the product is used is too humid, or the temperature is too high, which causes the screw teeth to be damaged.
