So, how does a PET blow molding machine work? It is a combination of smart engineering, compressed air, and right timing. However, when deciding on the suitable machine to fit your business, there is more to consider than the specification.

What is an blow moulding machine? It’s your ticket to strong, professional-quality plastic bottles made quickly, easily, and with great results every time. The extrusion blow moulding process turns simple plastic into powerful packaging and choosing the right machine can set your business up for long-term success.

Hot fill PET bottle is more and more popular use in juice, soy sauce, etc. Vfine hot fill bottle can  reach a maximum heat resistance temperature of 93°C. 
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.

PET bottle Hot filling technology introduction, includes PET material, Bottle production process,  bottle design,  and the applications.

Chinaplas, the largest rubber and plasic exhibition in Asia, which originally planned to be held in shang exhibition center, has been delayed for 3 years due to the covid 19, Chinaplas 2023 is bound to be a grand event and is expected to get enormous visitors flowrate.

Bottles made by blowing PET raw materials are called PET bottle packaging. PET bottle packaging, as a packaging material with a high market share, has many advantages
First of all, PET bottles are resistant to high temperatures, which is convenient for packaging and use of various high-temperature products. Secondly, PET bottle packaging has a high recycling rate and can be recycled. Thirdly, PET material has the feature of Non-toxic, transparent, formable, portable, and recyclable, with excellent air-tightness, giving the PET material a big application scope in the beverage, food, medicine, daily cleaning, toy, and chemical industry.

Pet material has been used in Cosmetic/cleaning/medicine packing industry for years, with very high appearance requirements, the PET bottle production of these industrial applicants, was on the one-step stretch blow molding machine since the marketing development begins, while along with the improvement 2-stage stretch blowing machine and injection machine performance, more and more makers switch the bottle making machine to the 2-stage type, Vfine PET blow molding machine is with the constant current heating controller, closely heaters, and inverter control of the heating oven temperature gives the preform a very even and balance environment, the preform infeed unit is adopted for automatic infeeding of the short neck support ring preform, which helps maker more choice of the container closure. Patent design for stretch unit helps bottle makers an excellent production for small bottle-neck to be 8mm in diameter.  These improvements give bottle makers more choices of the equipment.
