In regards to the Injection Moulding Process. Explain why
thicker parts can be more susceptible to shrinkage ,suggest two
methods to reduce the shrinkage for a given component geometry?
In regards to the Injection Moulding Process, discuss which
polymer properties influence the MFI (melt flow index) and how the
individual polymers MFI is related to the various processing
parameters for injection moulding. You can use diagrams to assist
with your answers if you like.
Explain how the processing parameters for INJECTION
MOULDING can influence the tensile strength for a
given polymer, explain this in terms of polymer properties.

Analyze the different types of defects that can be developed in
plastic injection moulding processes. Your analysis must include
the defects explanation, causes of the defects and the remedy of
reducing the defects
