How do we produce plastic bottles for commonly used cosmetics

Summary

: With the widespread dissemination of the aesthetic concept of beauty as justice among young consumers, cosmetic packaging has emerged as one of the few popular packaging categories. Beauty packaging tends to be more refined, and domestic and foreign consumers are increasingly paying attention to beauty product packaging

Firstly, the plastic material is made into a bottle embryo and then blown. Currently, environmentally friendly plastics are commonly used in PET<

& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp; Preheating is achieved by irradiating the prefabricated parts with a high-temperature lamp to soften and soften the main body of the prefabricated parts. 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 needed to cool it.

2. Bottle blowing molding

& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp; At this stage, the pre formed parts that have already been preheated are placed in the prepared mold and inflated to blow the pre formed parts into the required bottles<

& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp& Nbsp; The bottle blowing machines on the market are generally divided into fully automatic and semi-automatic. The automatic blow molding machine eliminates the need to manually place preheated prefabricated parts into the mold by combining robot operation with two operations of bottle blowing. Productivity has greatly accelerated, but of course the price is higher than semi-automatic.
