Pet bottle is a kind of packaging container widely used in food, beverage, cosmetics and other industries in recent years. With the continuous growth of market demand, pet bottle preform making machine has gradually become one of the important tools in these industries. Sinco will introduce in detail the working principle, advantages and related application scenarios of the pet preform making machine.
1. The working principle of pet preform making machine
The working principle of PET preform making machine is mainly to use the extruder to heat the PET raw material to a certain temperature and extrude it into a billet, and then cool the raw material in the mold to shape it. Specifically, the workflow of the pet preform making machine is as follows:
（1）Pretreatment of PET raw materials: PET raw materials are usually stored in the form of granules or flakes, and need to be dried and transported through pretreatment equipment to ensure the dryness and uniformity of the raw materials.
（2）Melting of PET raw materials: Put the pretreated PET raw materials into the extruder, heat and melt to make the PET raw materials reach a certain fluidity and extrudability.
（3）Extrusion of PET raw materials: Extrude the melted PET raw materials through a die to form a billet. The specific extrusion method can be continuous extrusion or intermittent extrusion.
（4）Cooling molding of PET blank raw materials: Send the extruded PET blank raw materials into the cooling mold for cooling and molding to complete the manufacture of PET bottle blanks.
2. Advantages of pet preform making machine
PET preform making machine has the following advantages:
（1）High production efficiency: The pet preform manufacturing machine has high production efficiency, and can quickly process PET raw materials into pet preforms, greatly improving production efficiency and production capacity.
（2）Stable product quality: The precise operation of the pet preform manufacturing machine can control the temperature and fluidity of PET raw materials, thereby ensuring the quality stability and consistency of the product.
（3）Low production cost: The cost of the PET bottle preform making machine is relatively low, and no additional molding and processing procedures are required in the production process, thereby reducing the production cost.
（4）Environmental protection and energy saving: No harmful substances are used in the production process of the pet preform making machine, and its energy saving effect is also very significant, which can greatly reduce energy consumption and environmental pollution.
（5）Wide range of applications: The pet preforms produced by the pet preform manufacturing machine can be widely used in food, beverage, cosmetics and other industries, and can meet the needs of different industries.
3. Application scenarios of pet preform making machine
The application scenarios of the pet preform manufacturing machine are very extensive, mainly including the following aspects:
（1）Food industry: The pet preform produced by the pet preform manufacturing machine can be used as food packaging, such as bottled beverage, bottled oil, bottled sauce, etc.
（2）Beverage industry: The pet preform produced by the pet preform manufacturing machine can be used as beverage packaging, such as bottled water, bottled juice, bottled tea, etc.
（3）Cosmetics industry: The pet preform produced by the pet preform manufacturing machine can be used as cosmetic packaging, such as bottled perfume, bottled shampoo, bottled shower gel, etc.
（4）Pharmaceutical industry: The pet preform produced by the pet preform manufacturing machine can be used as pharmaceutical packaging, such as bottled oral medicine, bottled injection, etc.
PET preform making machine is a production equipment with high efficiency, stable quality, low cost, environmental protection and energy saving, etc. It has a wide range of applications and can meet the needs of different industries. It is believed that with the continuous advancement of technology and the continuous expansion of the market, pet bottle preform manufacturing machines will be more widely used and developed in the future.
