Part II Course Details 1. Abstract (A 150-word description about the course) Mould and die making is one of the most important linkage industries of the plastics and metals industry which support the consumer products manufacturing. The aims of this course are to introduce to the students the basic concepts of tool design and develop their technical abilities to supervise a modern tool design office. Upon successfully completing this course, the students would gain an in-depth understanding of the principles and acquire basic technical skills concerning (i) design of moulds and press tools and dies for plastic and metal products in the watch, toy and electronic product manufacturing sectors; and (ii) the design of jig and fixture for manufacturing 2. Course Intended Learning Outcomes (CILOs) (CILOs state what the student is expected to be able to do at the end of the course according to a given standard of performance.) No. CILOs Weighting* (if applicable) Discovery-enriched curriculum related learning outcomes (please tick where appropriate) A1 A2 A3 1. List and use the general principles involved in mold and die design. 2. Demonstrate the application of the relevant principles concerning the design of jig and fixture for manufacturing 3. Apply the principles of mould design to the design of moulds for electronic product manufacturing sectors. 4. Apply the principles of press tool and die design to the design of press tools and dies for metal products in the watch, toy and * If weighting is assigned to CILOs, they should add up to 100%. N.A. A1: Attitude Develop an attitude of discovery/innovation/creativity, as demonstrated by students possessing a strong sense of curiosity, asking questions actively, challenging assumptions or engaging in inquiry together with teachers. A2: Ability Develop the ability/skill needed to discover/innovate/create, as demonstrated by students possessing critical thinking skills to assess ideas, acquiring research skills, synthesizing knowledge across disciplines or applying academic knowledge to self-life problems. A3: Accomplishments Demonstrate accomplishment of discovery/innovation/creativity through producing /constructing creative works/new artefacts, effective solutions to real-life problems or new 2
3. Teaching and Learning Activities (TLAs) (TLAs designed to facilitate students achievement of the CILOs.) TLA Brief Description CILO No. Hours/week (if applicable) 1 2 3 4 Lecture Explain key concepts, such as 2.5 hrs/week injection mould designs; jig & fixture design; die design; etc. Laboratory Learn and use 3DQuickMold and 3 hrs/week for 2 weeks Work Moldflow software to design moulds. Consultation Students meet the teaching staff on an individual or small group basis in his/her office for clearing doubts related to lectures or lab works. 1 hr/week @ Note: @ 1 hour per week will be scheduled as consultation hour for clearing doubts of students who can meet the teaching staff on an individual or small group basis in his/her office. When the class size exceeds 50 students, an additional consultation hour will be provided and the students will be divided into two groups. 4. Assessment Tasks/Activities (ATs) (ATs are designed to assess how well the students achieve the CILOs.) Assessment Tasks/Activities CILO No. Weighting* Remarks 1 2 3 4 Continuous Assessment: 40% Laboratory Reports 10% 2 reports to be submitted Assignment 15% Test 15% Examination: 60% (duration: 2.5 hours) * The weightings should add up to 100%. 100% For a student to pass the course, at least 30% of the maximum mark for both coursework and examination should be obtained. 3
