Firstly, the plastic material is made into a bottle embryo and then blown. Currently, environmentally friendly plastics are commonly used in PET<

 & Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp; Preheating is achieved by irradiating the prefabricated parts with a high-temperature lamp to soften and soften the main body of the prefabricated parts. In order to maintain the shape of the bottle mouth, the opening of the preform does not need to be heated, so a certain cooling device is needed to cool it.

        2. Bottle blowing molding

 & Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp; At this stage, the pre formed parts that have already been preheated are placed in the prepared mold and inflated to blow the pre formed parts into the required bottles<

 & Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp; The bottle blowing machines on the market are generally divided into fully automatic and semi-automatic. The automatic blow molding machine eliminates the need to manually place preheated prefabricated parts into the mold by combining robot operation with two operations of bottle blowing. Productivity has greatly accelerated, but of course the price is higher than semi-automatic.
