List and describe the sequence of events for injection molding.
Stages in injection molding are-
1.Filling (injection stage) : plarstic grannual are fed into hopper and heated by heater so melted plastic will form
2.Packing and cooling stage : melted plastic is fed into mold-die and cooled
3.Mold opening
4.Part ejection : After some time melted plastic takes the shaped of mold -die and becomes solid, and part is ejected by ejector pins and opening of mold-die
5.Mold closing : after part ejection, mold-die is again closed
