DSGN08054 2016 Mould, Tool & Product Design
The overall aim of this module is to enhance the students’ knowledge of the complex issues involved in the design of precision moulds, tools and products. Students will be introduced to the specialist areas of; mould, press tools and jig and fixtures in relation to design and become familiar with all the relevant documentation typically encountered in the precision engineering industry.
Learning Outcomes
On completion of this module the learner will/should be able to;
Demonstrate a comprehensive knowledge of the issues involved in the design of plastic products for high volume manufacturing.
Use a CAD system to preform advanced 3D solid and surface modelling and animation of mould, tool & product design.
Contribute to the design of special purpose machinery involving production aids, automation equipment, inspection, metrology, packaging and assembly.
Design a progression press tool involving piercing, blanking, cropping and forming operations.
Design single cavity injection mould of reasonable complexity and produce all the relevant models, drawings and documentation necessary for its specification.
