Good thermal conductivity not only refers to the good thermal conductivity of the embedded parts, but also the good thermal conductivity of the embedded screws. Most of the parts connected by the embedded parts transfer heat from the threads and the inner wall of the mold;

The effectiveness of the insert depends on the thickness of "a" shown in the figure, which depends on the amount of heat received by the entire insert during the rotational molding process. The greater the heat received, the thicker the wrapping and the better the strength. If sufficient heat is not obtained, it will be very thin, and the torque resistance performance will deteriorate, making it easy to loosen during use.
