There is a monster machine at the SHENZHEN workshop. It is a plastic bottle preform machine. This machine is very important since it ensures that all bottles are manufactured correctly.
The plastic bottle blow molding machine operates by melting tiny plastic beads to a hot liquid. Next, a liquid plastic is poured into a bottle-shaped mould. The plastic is inflated like a balloon using air, taking the form of the mold. When the plastic hardens, the mold is opened, and out comes a perfect plastic bottle! This step helps ensure that all the bottles are identical.
