What was the process of the bottle blower when he blew the bottle?
May 24, 2018

At present, most bottling machines are still two-step bottling machines, that is, plastic raw materials must be made into bottle embryos before blowing. Nowadays, PET is commonly used as an environmentally friendly plastic.
The process of blowing bottles is divided into two parts:
Pre-heating
The bottle embryo is irradiated by a high-temperature lamp tube and the body of the bottle embryo is partially heated and softened. In order to maintain the shape of the bottle mouth, the bottle embryo mouth does not need to be heated, so it needs a certain cooling device to cool it.
Second, blowing bottle molding
This stage is to place the pre-heated bottle embryo into the mold that has been prepared, and to inflate it with high pressure, and blow the bottle embryo into the required bottle.
Bottle blowers on the market are generally divided into automatic and semi-automatic.
The automatic blowing machine combines the two operations of the blowing bottle through the operation of the manipulator, eliminating the process of placing the pre-heated bottle embryo into the mold by the middle manual. The speed of production has been greatly accelerated, and of course the price is also higher than that of semi-automatic.
