How does a PET blow moulding machine function?
Plastic products are an integral part of our everyday lives, from water bottles to food containers. One of the key techniques used to manufacture these plastic products is blow moulding. Specifically, PET blow moulding machines are commonly used in the production of PET bottles. These machines play a crucial role in shaping plastic materials into the desired form, allowing manufacturers to create a wide range of products efficiently and cost-effectively.
What is a PET blow moulding machine?
A PET blow moulding machine is a piece of equipment used in the manufacturing industry to produce PET bottles. PET, which stands for polyethylene terephthalate, is a thermoplastic polymer resin commonly used in the production of plastic bottles for various beverages and household products. The blow moulding process involves heating a preform, which is a small plastic tube made of PET resin, to a specific temperature and then blowing compressed air into the preform to expand it into the shape of a mold.
These machines typically consist of several components, including a feeding system for the raw materials, a heating system to melt the preform, a blowing system to shape the plastic, and a cooling system to solidify the final product. The operation of a PET blow moulding machine requires precise control and coordination of these components to ensure the quality and consistency of the produced bottles.
How does a PET blow moulding machine work?
The process of manufacturing PET bottles using a blow moulding machine can be broken down into several key steps. Firstly, the raw PET material is fed into the machine through a hopper, where it is heated and melted to form a molten resin. The molten resin is then extruded into a tube shape, known as a preform, which is transferred to the moulding station.
At the moulding station, the preform is placed inside a mold cavity, where it is clamped and stretched to the desired shape using a blowing rod. Compressed air is then blown into the preform, forcing it to expand and take on the shape of the mold. The cooling system is then activated to cool the newly formed bottle, allowing it to solidify and maintain its shape.
The entire process is controlled by a computerized system that regulates the temperature, pressure, and timing of each stage to ensure the quality and consistency of the produced bottles. Once the bottle has cooled and solidified, it is ejected from the mold cavity and transferred to the trimming and finishing station, where any excess material is removed, and the bottle is inspected for quality control.

.The production principle of PET hot-filling bottles is basically the same as that of ordinary PET bottles, but the production process and production conditions are much more complex. Currently, our company mainly adopts a one-time blow-two-way stretch high-temperature heat setting production process. The following is its main production process:The production of hot-filling bottles involves additional steps such as mold heating, air cooling and two-step stretching compared to ordinary PET bottles, which increases the complexity of the bottle blowing process. At the same time, due to the longer crystallization time required for the bottles during the bottle blowing process, their blowing speed is also much slower than ordinary PET bottles.It should be noted that product performance is closely related to the bottle blowing production speed. Generally speaking, the slower the speed, the better the product performance.
