Writing Feedback / Task 1.The diagram shows how raw materials are used to make plastic products. Summarise the diagram. [3]

The process of plastic production is illustrated in the given diagram.

The plastic production process is started when the raw materials are loaded from the oil refinery to the plant. Afterwards, the materials will be stored into a large container before being mechanically sent to a high pressure, long molecules of plastic are finally formed. The next step is that the plastic granules will be funneled to an injection moulder which is used to melt the plastic and force it into required moulds.

The hardened products will be carefully observed and inspected by the quality experts after the products are released from the moulder. Before being packaged in the a storehouse, if the products pass the inspection, they will be placed orderly on the conveyor belt to the package stage while the defected ones or wasted materials will be discarded. The complete stage is described when finished products can be packed into boxes and stored in the storehouse, ending the process of plastic production.

In conclusion, the plastic production process is relatively complicated with the aid of machinery, illustrating the major stages in plastic production.
