The diagram illustrates the process of how raw materials are used to produce plastic products. Overall, it can be seen that plastic production involves multiple stages, starting from oil refining to packing and storing the finished products in a warehouse.
Firstly, raw material is obtained from an oil refinery. This material is then transferred to a high-pressure oven, where it is processed to create long molecules of plastic. After this stage, these molecules are converted into plastic granules. The granules are then melted by an injection moulder, which forces the melted plastic into a mould to create the desired product shape.
Once the mould releases the product, it undergoes quality control to ensure it meets the required standards. Any waste product is separated during this stage. Finally, the finished plastic products are packed and stored in a warehouse, ready for distribution.
Overall, the production of plastic products is a complex, multi-step process that requires refining, moulding, and strict quality checks before being packed for storage and distribution.
