The design and selection of plastic bottle production equipment must be considered based on production needs, product specifications and budget factors. Choosing suitable equipment can improve production efficiency and reduce production costs. However, due to the long-term processing and mold removal of the upper end of the mold, which will cause scratches, the upper end of the mold is uneven, resulting in gaps when the air pipe is pressed down and fits with the mold during blow molding, thereby reducing the sealing, causing the blowing pressure to be lost, resulting in an increase in the residual rate of the blow-molded plastic bottle.
