The Materials and Manufacture area is one of the two areas of study in SQA Higher Design and Manufacture, an SCQF level 6 course. It covers the materials products are made from and how they are made: the three material groups and their properties, the processes that shape them, the scales and systems of production, finishes and joining, and the impact of all this on society, the environment and the workforce. This page maps the key areas and links to the answer pages for each.
What the Materials and Manufacture area covers
This area is about materials, processes and consequences. The course expects you to reason from properties and to understand how products are actually made and what effect that has.
- The three material groups
- Timbers (natural hardwoods and softwoods, and manufactured boards), metals (ferrous, non-ferrous and alloys) and polymers (thermoplastics and thermosetting plastics), with the properties that decide which is chosen.
- Manufacturing processes
- Moulding and forming of polymers (injection moulding, vacuum forming, blow moulding), casting and forming of metals, and the cutting, shaping and joining of timbers.
- Scales of production and manufacturing systems
- One-off, batch and mass or continuous production, and the systems that keep products consistent: standardisation, tolerance, jigs and templates, and CAD/CAM.
- Finishes and joining
- Why finishes are applied and which suit each material, and permanent and temporary fixings and fittings, including knock-down fittings.
- Impact on society and the environment
- Sustainability and the six Rs, resource use and waste, planned obsolescence, and the effects of automation and global manufacture on the workforce.
How this area is assessed
The Materials and Manufacture area is examined mainly in the question paper and supports the assignment.
- Question paper - knowledge and explanation questions on material properties and choices, manufacturing processes, scales of production, finishes and joining, and the impact of manufacture on society and the environment.
- Assignment - the candidate must choose and justify materials, processes and finishes for the outcome and consider how it would be made and how to reduce its impact.
How to study the Materials and Manufacture area
This area rewards reasoning from properties and knowing how things are made.
- Reason from properties. Never just name a material - link a property (corrosion resistance, lightness, formability, heat resistance) to the product.
- Know the key processes in stages. Be able to describe injection moulding and vacuum forming step by step and say which scale each suits.
- Match process to scale. High-tooling processes need high volume; cheap-tooling processes suit one-offs and prototypes.
- Apply the six Rs. Treat them as design decisions for a product, not a list.
- Practise past papers. Use SQA past papers, marking instructions and the data booklet to learn the question style and rewarded wording.
