Learning, Teaching and Assessment (LTA) Approach:
Learning & Teaching:
Lectures, supported by notes will introduce concepts and provide a framework of self-study. Tutorials will apply design principles to examples of injection moulds, extrusion dies and finished plastics products. Practical work will involve the introduction to process simulation software to assist with the design of moulds and plastics parts. Case studies and industrial visits will connect classroom-based work with commercial practice and establish an industrial context for the module material. Self-assessment questions will provide individual feedback of progress and promote self-study. Much of the material will be made available on-line through Moodle. Use will be made of information from websites and CD-ROMs supplied by major companies and the trade press.

Assessment:
Assessment by coursework involving the analysis of a moulded plastics product and design of a mould together with a written examination.

Internationalisation:
Case studies will be taken from products manufactured around the world and students will be made aware of product design guidelines and manufacturing and testing standards from various countries and regions.

Employability:
Skills, knowledge and problem-solving capability developed in this module will benefit potential employers as very few students will have similar expertise or skill sets.

Research/ teaching linkages
Module tutors undertake research & consultancy in this subject area and attend events which keep them up to date with the subject material. Students can also attend technical meetings and lectures delivered by experts in the field. Much of the teaching material is based on industrial case studies.

Equality and diversity:
Lecture materials are available in hard and electronic format (on Moodle). Timetabled academic supervision is available each taught week of the module to support students. Engineering Plus is provided by the School as a drop-in support facility for all students.

Formative Assessment:
The University is currently undertaking work to improve the quality of information provided on methods of assessment and feedback. Please refer to the section on Learning and Teaching Approaches above for further information about this module’s learning, teaching and assessment practices, including formative and summative approaches.

Summative Assessment:
The University is currently undertaking work to improve the quality of information provided on methods of assessment and feedback.

Description of module content:

Topics include: design strategies and guidelines for optimising plastics product design including design for manufacturability, suitability for service, disassembly and recycling; basic injection mould and extrusion die design for plastics products together with a consideration of associated costs; the application of software to assist with the design of injection moulds and plastics parts; typical faults found in moulded and extruded products and their remedies.

Learning Outcomes for module:

On completion of this module you will be able to:
LO1: apply a critical understanding of product design strategies and produce an outline product design specification;
LO2: apply critical understanding of materials properties to select suitable combinations of materials and manufacturing processes for prototype and finished products;
LO3: assess the basic principles employed in the design of injection moulds, extrusion dies and selected plastics products including the use of computer software;
LO4: recognise and evaluate the faults occurring in moulded and extruded products, explain their causes and suggest appropriate remedies.
