Development history of pet bottle blowing machine

The early PET bottle blowing machine used single-step bottle blowing technology.

1, the early PET bottle blowing machine used single-step bottle blowing technology, which could only produce smaller bottles, and the speed was slow.

2. With the development of technology, PET bottle blowing machine gradually adopts two-step bottle blowing technology, which can complete preheating and bottle blowing processes at the same time, greatly improving production efficiency.

3. In order to better meet the market demand, PET bottle blowing machine has gradually developed multi-layer bottle blowing machine technology, which can realize different material combinations on the same bottle, such as increasing wall thickness and improving corrosion resistance.

4. With the development of computer technology, the PET bottle blowing machine began to adopt digital control system, which can achieve higher control accuracy and faster response speed, thus better ensuring product quality.
