Optimized preform design ensures dynamic bottle blowing success

The difficulties of the 72-cavity PET bottle preform mold mainly include the following aspects:

Mold design: The 72-cavity PET preform mold needs to take into account the layout and arrangement of the 72 cavities to ensure that the flow channels and cooling systems of each cavity are evenly distributed to ensure the consistency of temperature and fluidity during the injection molding process. .

Material selection: PET material has a high melting point and thermal shrinkage rate, and has higher requirements for mold materials. Mold materials need to have good wear resistance, corrosion resistance and thermal conductivity to ensure the service life of the mold and the quality of injection molding.

Injection molding process control: The injection molding process of the 72-cavity PET preform mold requires precise control of parameters such as temperature, pressure, and speed to ensure the consistency of the size and quality of the preforms injected in each cavity. At the same time, attention also needs to be paid to preventing shrinkage holes, warping and other defects in the preforms

Injection molding advantages:

High production efficiency: 72-cavity PET bottle preform mold can injection mold 72 bottle preforms at one time. Compared with lower-cavity molds, 72-cavity molds can produce more products in the same time, improving production efficiency.

Stable product quality: The design and manufacturing precision of the 72-cavity PET bottle preform mold is high, which can ensure the consistency of the size and quality of the bottle preforms injected at each cavity. At the same time, the consistency of temperature and fluidity during the injection molding process can also be better controlled, reducing product defect rates.

Cost saving: The 72-cavity PET preform mold has high production efficiency and can reduce labor and equipment usage costs. At the same time, due to the stable product quality, the scrap rate is reduced and the production cost is reduced.

Environmental protection and energy saving: Injection molding is a relatively environmentally friendly production method. Through the use of 72-cavity PET preform molds, the consumption of raw materials and the generation of waste can be reduced, achieving the effect of energy saving and emission reduction... please send us a message (Email: info@ansixtech.com ) at any time and our team will reply to you within 12 hours.
