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