Of course, adjustable molds with the function of fully automatically adjusting the size of the opening are also available in the market. Although the opening size of the full-automatic adjustable die can be quickly and conveniently adjusted, the labor is saved, and the efficiency is improved, the manufacturing cost is very high due to the existence of the components such as the control part, the motor and the starting part, and the occupied space of the whole adjustable die is also large due to the fact that air compression equipment needs to be equipped.
