Deforming

HideShow resource information
Name 7 deforming methods.
Laminating, folding, forging, bending, blow moulding, vacuum forming and press moulding.
1 of 9
What are the stages of laminating?
1. Glue two or more thin strips of wood together. 2. Place it in a jig. 3. Let it dry so the shape forms and holds.
2 of 9
What are the stages of bending?
1. Heat the metal. 2. Place it in a bending jig.
3 of 9
What are the stages of folding?
1. Take a piece of sheet metal. 2. Mark out the desired outline. 3. Bend the metal using folding bars, formers and mallets. 4. Corners are joined using rivets, soldering, brazing, etc.

What are the stages for plastic folding?
1. Line bending is ideal. 2. It can be done manually or with a strip heater.

What is forging and the stages?
A forge is a fire with air being blown into the centre of it. 1. Heat the metal in the forge. When it is hot enough to have softened efficiently it can be hammered into shape using an anvil. Used on iron and steel.

What are the stages of press moulding?
1. Place powdered thermosetting plastic into a female mould. 2. A former is pressed on it, pushing the plastic into the mould. 3. The plastic is heated until its a liquid and let to cool. Leaving it in a permanent shape.

What are the stages of vacuum forming?
1. Thermoplastic is heated until soft. 2. A pattern is placed on the vacuum bed. The pattern is raised up to the plastic. 3. The air is sucked out. Atmospheric pressure forces the plastic onto the mould.
8 of 9
What is blow moulding?
1. A sheet of thermoplastic is clamped to the mould. It is heated. 2. Air is blown under it forcing it to take the shape of the inside of the mould. It forms domes. Used to make bottles and containers.
