Manufacturing Process of Plastic Granules
Creating plastic granules is a multi-step process that transforms raw materials into the versatile pellets used in manufacturing.
Raw Materials
The process begins with petrochemicals derived from natural gas and crude oil. These raw materials are the building blocks for most plastics.
Polymerization
Polymerization is a chemical reaction where small molecules called monomers join together to form long chains, or polymers. This process can be tailored to produce different types of plastics.
Extrusion Process
In extrusion, the polymer is melted and pushed through a die to create a continuous shape. This shape is then cooled and cut into granules.
Cooling and Cutting
The hot plastic is cooled using water or air, solidifying it into a manageable form. It is then cut into small, uniform granules ready for shipment to manufacturers.
