Lesson details

Key learning points

  1. Reforming materials changes the shape and the state
  2. Injection moulding is a reforming process for polymers.
  3. Casting is a reforming process for metals.

Keywords

  • Reforming - changing the material shape and state

  • Molten - made liquid by heat

  • Mould - a hollow shape which can be used to form materials

Common misconception

Reforming is the same as deforming.

Reforming changes the state AND the shape; solid, liquid and back to solid. Deforming only changes the shape; the materials always remain a solid.
