Hi! I would love to see comments based upon IELTS marking criteria, and possibly a detailed band score!
Thank you!

Task 1: Plastic bottle production process.



WORD COUNT: 160

The diagram illustrates how a plastic bottle is made. Overall, there are 6 stages in the production process. The principle concept requires the plastic to be heated and shaped to form a bottle.

The process begins when a preform is placed inside an extruder machine with a heat source. Once the piece melts, the machine is removed. Subsequently, four separate pieces of mould then enclose to form a bottle shape surrounding the preform, which stays at the cap of the structure.

The preform stays within the mould for the majority of the production period for the shaping purpose. Now in the 4th and 5th stages, through the opening, a needle is injected to the preform to discharge pressurized air. The hot, therefore malleable, material expands along the moulds until a desirable shape emerges. It is let cold down and the mould pieces are removed by this time. At the final stage of the process, a plastic bottle is successfully produced.

Ok. Let's go criteria by criteria on this one. Here we go!

TA - 6: You clearly understood and represented each step of the bottle making process. You were detailed in your description and never missed out on describing a single manufacturing process. It would have been better if you had summarized the 6 stage process in the overview as something similar to a trending statement.

C&C - 6: While there is an overall progression in your presentation, there are times when the coherence of the presentation is confusing to read. Specifically the 2nd sentence of the last paragraph.

LR - 6 : There are some instances when your word formation of usage is difficult to understand but the rest of the paragraph content helps to clarify what you are trying to say. The problem can be seen in *P3 : S4

GRA: 6: There are some grammar errors throughout the essay but these do not impede understanding of the paragraph. Try to improve on your simple and complex sentence mixes in the presentation to further increase the score.

* P = paragraph S = Sentence
