The following diagram illustrates the complex process of how raw materials are used to produce plastics. The whole process is required to have three working people and the main six steps of process have to be done successfully to get a plastic. Additionally, there are two important equipments, high pressure oven and injection moulder, are used to transferall chemicals/molecules to plastics.
First of all, raw materials is collected from oil refinery and it should be prepared/Stored to first step. That stored raw material goes to the high pressure oven to mix with long molecules of plastics. After these processes, the plastic granules will be made and transfer to the important equipment, injection moulder.
Most importantly, this injection moulder melts the plastic and forcefully transforms it into mould. Until then, there are no needs of humans, all processes done by machinery. Once after mould releases final product, the first worker will get classified the product and throw away the waste product.
After that, second worker, the quality controller checks all the products that are ready for packaging. Following that, the packager will pack the final product and make them be prepared to transport to storage in warehouse.
In general, after all these complex processes, raw material transformed to the plastic, the final product and be ready to sell it in market.
