The types of bottle making machines will not be introduced too much here. Before using this kind of equipment, we should understand it in advance. The turning line is familiar to some people. You can know what a turning line is. What? In order to understand the confusion, we checked the relevant information, and finally found the corresponding information, let's take a look at it in detail.

　　The vacuum-assisted molding process of the determinant bottle making machine can significantly improve the molding process. It is reflected in that it can improve the uniformity of the wall thickness of the glass packaging container product. More importantly, it can increase the speed of the molding machine and reduce the weight of the product moderately; and it can also reduce the consumption of compressed air. 

　　Reversal line: The pliers arm is turned back to make the die in the correct position of the preliminary mold/forming mold. The center line of rotation passed at this time is called the reversal line, which serves as the design reference line for the mold or the pliers arm.

　　Because the flip line is an imaginary line, we cannot see it. There are two types of reversal lines: mechanical reversal lines and mold reversal lines. The mechanical turning line passes through the center line of the pliers mechanism (the center of operation of the pliers arm) and becomes the design standard of ISM. The mold turning line is a line that drops 1.2mm from the mechanical turning line.
