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.

4783 Minh, where is the diagram and instructions for this task? It will be difficult for me to offer you the correct reviews and revisions, or point for improvement if I do not know what your instructions are and what the diagram looked like for this task. I suggest that you upload both to this thread as soon as you can so that I can get a better idea as to how I can help you improve your writing skills. Good work though on writing more than 150 words. However, your conclusion is too short and does not meet the minimum 3 sentence requirement meant to help you properly close the essay. You will lose points for that in the actual test. In the meantime, I will wait for the diagram so that I can better review the content of the first two paragraphs for you. Please post the instructions and the diagram as soon as a you can. Thank you.

Firstly, you need improvement for your systematical writing. In the first paragraph, it is supposed to contain a paraphrase of question and overview. As we have seen, you directly explained detailed information. Indeed, you have the overview, but you place it in the last paragraph. It doesn't matter, but you have to remember that the good paragraph has at least 3 sentences. Besides that, you are expected to fight the time because you only have time for 20 minutes for finishing this. To play safely. you should locate the overview in the first paragraph.
Following that, you need making improvement in your flow. Harnessing proper linking words is the good way to make your flow smoother. I really believe you can master this section on condition that you wanna practice more and more
Happy writing
GOOD LUCK
