What are the production processes for plastic bottles

The production process of plastic bottles includes:

1. Compression molding, also known as molding in industry, is the first step in the processing of plastic bottles used for the formation of thermosetting plastics such as phenolic resins and unsaturated polyester resins.

2. Extrusion molding, also known as extrusion molding, is a method of extruding products of the desired shape by continuously passing heated resin through a mold using an extruder.

3. Injection molding, also known as injection molding, is a method of obtaining products by using an injection molding machine to inject thermoplastic melt into a mold under high pressure and then cooling and solidifying it.

4. Blow molding, also known as hollow blow molding, is a method of using compressed air pressure to blow and expand the hot resin preform closed in the mold into a hollow product.
