Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
Pupils will handle, shape and join sheet materials using different manufacturing processes. They will test and experiment with different mechanical fixing methods and adhesives and then use this knowledge to explain which choices are suitable and why.
Lesson Summary
You will learn to identify and use reforming manufacturing processes.
Key Notes
- Reforming materials changes the shape and the state.
- Injection moulding is a reforming process for polymers.
- Casting is a reforming process for metals.
Vocabulary To Learn
- reforming: changing the material shape and state
- molten: made liquid by heat
- mould: a hollow shape which can be used to form materials
Common Mistakes To Avoid
- Reforming is the same as deforming.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Reforming materials changes the shape and the state. Injection moulding is a reforming process for polymers.
2. What does this key word mean in this lesson? 'reforming'
changing the material shape and state.
3. Correct this common mistake.
Mistake: Reforming is the same as deforming. Correction: Reforming changes the state AND the shape; solid, liquid and back to solid. Deforming only changes the shape; the materials always remain a solid.
