Question

1. Inspect various plastic components in a typical automobile, and identify the processes that could have been used in making them.
2. It is well known that plastic forks, spoons, and knives are not particularly rigid. What suggestions would you have to make them better? Describe processes that could be used for producing them.

Answer 1

Page 1 Various plastic components in a automobile and identify that could have been used in making them. typical processes the It i make Plastic is used widely in automobile, used to Various components of automobile, plastic is used because It decreases the overall weight of t .the automobile and with decrease in of automobile increases the fuel efficiency weight Various plastic component in a Typical automobile are ' fuel tank, seats, inner door, bumper, grillex instruement panel. They all are plastic material process involved in making such made with done Components in plastic automobiles are in Infection Moulding - It is a manufacturing process in which various plastic or thermoplastic components are made it is by producing molten material into mould by injecting it and material mater parts that are infected into the mould there material of mould plays an important in the moulding process role molten plastic material are ingeted into the mould and then solidification, takes place aped produed in required Shape. is designed

page 2 also a Which plastic ar raw melted ared is (1) Plastic Extrusion :- It is manufactersing processes in basically a plastic material is required designed are formed in Continuous shape. The material melted by generation of mechanical energy or by various specialized heaters. This is done Various expresion temperature and meeting is also done by turning of screws (1) polymer counting. It is manufacturing process of plastic component in which made desired & hapee by immersing it into polymer solution then layer of is formed then it In automobile it is used for only specific components. in plastic component are mould extracted.

plastic forks, forks, &poons and knives polystyrene and Then it made to plastic sheet and page-3 processes that could be used for Prodening for producing spoons ared knives and how it Would be make them better Plastic are made from various plastic material there are mainly two types of materials are polypropylene. These were prodered through polymerization. Polymerization - It is the process in Chemical reactions takes through which monomer is chain of polymer and then through polymer various kind of plastic components are made. After that it is manufactured into small pellets and then et is taken for assembly where it is melted and Spoons, knives ared plantic forks are into & hape. and forths can be increased by increasing Then rigidity of plastic Knines, Spoon cut it to carefully to produce bether Structure in this way it is increased by its rigidity. which Various into Cutted
