What is the cost effective solution for fast manufacturing of PET bottles or bottle blanks? There is no doubt that finding a PET injection molding machine with high quality and low price is the best solution. Today we will discuss PET injection molding machines and our selection of the best PET injection molding machines for 2021.

What is a PET injection molding machine

PET preform injection molding machines are specifically designed for PET preforms of various sizes. PET injection molding machines use PET-specific screws to greatly increase plasticization speed and injection weight.

PET injection molding machine PET injection molding machine is the same as any other injection molding machine for PE, PP, etc.

The difference is that it does not make the final product, but rather the bottle blanks.

Usually, a PET blow molding machine requires a PET injection molding machine separate from the unit or integrated.

When you inject a plastic object, your mold has an external and internal shape, with the space between the two filled with plastic to form the object.

For PET bottles this is difficult because you cannot remove the internal shape from it.

So preforms are injected, which are spiral tops and hollow, tubular shapes.

At the filling machine, the top is firmly grasped and the PET bottle preform is heated and placed in an outer mold into which compressed air is then blown.

The bottle is then shaped in the form of an external mold, simple and agile.

This is how all PET bottles are produced.
