    The quality of the machine depends on the machining quality of the part and the assembly quality of the machine. The machining quality of the part includes the machining accuracy and appearance quality of the two parts. The machining accuracy refers to the actual geometric parameters (size, shape and orientation) and ideal geometry after the machining of the part. The degree to which the parameters agree.

    The stage where the parison is extruded from the gap between the die lip and the die core is called the blanking stage. At this moment, common phenomena are the swelling of the embryo and the vertical extension of the embryo. The factors affecting these two phenomena are: the die diameter and wall thickness control system of the blow molding machine, where the control system includes the axial wall thickness control system and the circumferential wall thickness control system, which are used to adjust the gap between the die lip and the core of.
