How do we usually produce plastic bottles for cosmetics?

Everyone must be very curious, how do we usually produce cosmetic bottles? Now let me take everyone to see how to do it!
First, the plastic material is made into a preform and then blown. At present, environmentally friendly plastics are commonly used in PET.


  1. The preheating irradiates the preform with a high-temperature lamp to soften and soften the main part of the preform. In order to maintain the shape of the bottle mouth, the opening of the preform does not need to be heated, so a certain cooling device is required to cool it.

At this stage, the pre-heated preform is put into the prepared mold and inflated therein to blow the preform into the desired bottle.

Bottle blowing machines on the market are generally divided into automatic and semi-automatic. The automatic blow molding machine combines the two operations of blowing the bottle through the operation of the robot, eliminating the need to manually put the preheated preform into the mold. Productivity is greatly accelerated, and of course the price is higher than semi-automatic.


It turns out that the plastic bottles of cosmetics we usually use are produced in this way, do you know?
