The extrusion blow molding process of the semi-automatic juice bottle blowing machine consists of 5 steps: 1. Making plastic preforms from the plasticized raw materials; 2. Cut off a portion of the embryo by closing the mold and cutting off the embryo; 3. Fill the mold cavity with gas to shape the embryo and cool it down; 4. Open the mold and take out the molded container; 5. Trim the edges to obtain the finished product. During the preheating process, the preform (embryo) is irradiated through an infrared high-temperature lamp to heat and soften the body of the preform (embryo). In order to maintain the shape of the bottle mouth, the preform (embryo) mouth does not need to be heated, so a certain cooling device is required to cool it. The blow molding stage involves placing the preheated preform (embryo) into a pre made blow mold, inflating it with high pressure, and blowing and pulling the preform (embryo) into the desired bottle. The bottle blowing machines on the market are generally divided into two types: fully automatic and semi-automatic. The fully automatic bottle blowing machine combines the two bottle blowing operations through the operation of a robotic arm, eliminating the need for manual placement of preheated bottle preforms into the blowing mold. Greatly speeding up the production rate, of course, the price is also higher than semi-automatic. How to choose the desired blow molding machine model is undoubtedly the most concerning topic for everyone. Generally speaking, choose the model of blow molding machine based on the product you need. For manufacturers with different dosages, they generally focus on the number of cavities produced, the size of the bottle capacity, and the hourly output. It is crucial to choose the model that meets your needs based on your own needs.
