Plastic bottle products are mainly materials such as polyethylene or polypropylene, and after adding a plurality of organic additives, after heating of high temperature, the plastic container made of blow molding, extrusion, or injection molding process is made by plastic molds. It has the advantages of light weight, high transparency, not broken, and low cost, is widely used in food, beverage, pickles, honey, dried fruit, edible oil, pertish, etc., liquid or solid disposable packaging. Under normal conditions, the manufacturing process of plastic bottles mainly includes several types of squeezing, injection, injection molding, and two steps.
The following are the manufacturing processes of the plastic bottle. 1. Extrusion Process: The bottom of the plastic bottle in this process has a bottom sewing, the specifications can be adjusted by themselves, thin and thick. The randomness of processing is relatively large.
Can be used for processing of materials such as polyethylene, polypropylene, high barrier. 2. Inflowing process: Both the bottom of the plastic bottle in this process without bottom seam, good gloss, fully automatic production, thin, uncomfortable, dependent on the size of the mold. It can be used for the processing of polyethylene, polypropine.
3, injection molding process: This process is basically the same, all the lids and plastic boxes are produced by injection molding process, and the benzene material is produced in this process. It is the difference between it. Its inner diameter from the bottom to the mouth is an injection molding process, the bottom is large, and the closet is a blow blowing process. 4, two-step process: This process needs to close the blank, and then blow bottle, blow into a variety of bottles according to the mold of the bottle. Usually the polyester material is carried out in this process production.
In addition to the above major production processes, there is a blister process, which is only used in the production of plastic products. With the continuous development of science and technology, it is believed that the production process of plastic bottles will become more and more technological.
