Engineering Studies – P1 Fundamental Engineering – Materials and Manufacturing
This topic introduces manufacturing methods applicable to various materials and shape requirements. The fundamental relationship between properties and manufacturing technique are key concepts of this topic.
- The fundamentals of shaping materials
- Relating the material to the shape requirements
- Relating the shaping process to the shape requirements
- Discuss each of these categories of shaping material:
- casting – the pouring of liquid into prepared moulds
- manipulative processes – involving plastic deformation of the material
- powder techniques – the shape is produced by compacting a powder
- cutting, joining and grinding operations
- Explain how the shaping processes are dependent on material used and shape requirements of the product.
- Describe the production of items considering the raw materials, preparation for forming, the forming process, and testing for quality.
- For metals: discriminate between cold working processes (press work, cold forging, rolling, coining) and hot working (casting, hot forging, powder forming).
- For thermosetting polymers: hot compression moulding, transfer moulding.
- For thermosoftening polymers: Injection moulding, extrusion, blow moulding, calendaring, vacuum forming.
- For ceramics, including glass: hand forming, flat drawn glass (Industrial glass), blown glass, casting, extrusion (bricks).
