Activities and Assessment Scheme:
N Activity Marks
(up to)
1 Design a model for injection moulding, suitable for two-part mould. Typical suitable
artefacts are: ice tray, pet’s bowl, paint tray, make-up box, egg box, switch cover, network
socket cover, etc.; On the visible surface add a logo of your product, on hidden surface add
a serial number in the following format UP123456 (where 123456 is your student number)
10
2 Modify the model introducing all relevant draft angles and rounds. Check the model
integrity;
5
3 Using Plastics Advisor determine the most effective injection strategy and optimise the part
design;
10
4 Design a set of two moulding dies incorporating suitable cavities and gating system; 25
5 Apply shrinkage, make a test shot and examine the moulding. Calculate the required clamp
force, if the injection pressure is 100 MPa;
10
6 Demonstrate the mould opening sequence and examine the mould parts; 5
7 Choose one of the moulding inserts, suggest an appropriate manufacturing process plan
and simulate the manufacture of a moulding die in mild steel;
15
8 Select appropriate cutting tools and parameters, estimate the machining time. Discuss
some alternative methods for machining;
5
9 Choose one of the moulding inserts and generate a technical drawing for it. 5
10 Produce a comprehensive and concise (2,500-word max) reflective report presenting your
work alongside all essential screen dumps with relevant comments and project evaluation.

Assessment:
Assessment grades for this module will be based on submitted work. To qualify for each grade, the minimum
expectation of the progress is listed below:
Grade Progress
0-39% Poor progress and lack of basic understanding. Presented work is not sufficient or according to
the requirements.
40-49% The student demonstrates some basic understanding of most of the learning outcomes.
Essential parts of the Design for Manufacturing, Manufacturing, Machining constraints and
Econometrics are missing.
50-59% The student demonstrates basic understanding of most of the learning outcomes, including
essential parts of the Design for Manufacturing, Manufacturing, Machining constraints and
Econometrics
60-69% Demonstrating a good understanding of the Design for Manufacturing, Manufacturing,
Machining constraints and Econometrics.
70%+ As above and some innovative approaches to ensure product quality and topology optimisation
to ensure optimum performance of the components. CNC time optimization.
