Pet Preform Mould factory direct sales of products used in the food industry, this type of products in the processing and production requirements are more stringent, today we will come to understand its production process.

There are two kinds of production processes for pet preform molds. One is the extrusion blowing process, that is, the PET raw materials are added into the extruder, and the molten parison is extruded by heating and melt molding, and then put into a bottle mold to form an inflation molding. Remove from the mold after cooling and setting. The two are injection-blowing processes, that is, PET raw materials are injection-molded into a tubular parison by an injection molding machine, and then placed in a bottle mold by stretch-blowing molding, and cooled to obtain a finished product. This is mainly used to produce PET bottles, such as mineral water bottles.

Of course, the Pet Preforms produced should be tested and tested, especially in terms of hygiene. This will ensure food safety and prevent packaging from contaminating dried fruits and other foods and affecting our health.
