A phone housing case is to be manufactured from Polyester Based- Thermoplastic Polyurethanes (TPU) with the manufacturing processof Injection Moulding
**Problem** :
a. Describe how temperature is involved in each stage of theinjection moulding process
b. How temperature in the injection mouldingprocess influences the internal structure of the material
c. The defects that could likely be introduced due totemperature in the injection moulding process
d. The mechanical property issues that could be caused iftemperature is not correctly controlled during the injectionmoulding process.
