The diagram below shows how raw materials are used to make plastic products. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The diagram illustrates the various stages in the production of plastic items. Clearly this is a complex process that requires a range of equipment and machinery and, at some stages, skilled workers. Initially, the raw materials have to be transported from the oil refinery to the plant. On arrival, they are poured into a large […]

The given diagram illustrates the process of how raw materials are used to produce plastic products. It can be seen that plastic production involves several steps, from starting to packing and storing the finished products in a storage area. Initially, basic material obtained from an oil refinery then is transferred to a high-pressure oven, where […]

The process diagram illustrates how plastic goods are manufactured using unprocessed materials obtained from an oil refinery. First, the raw materials are brought to the factory from the oil refinery. The oil then enters the factory, where it is passed into an oven that melts the raw materials at a specific temperature, forming long molecules […]
