- Graphics - Question 11
- HDPE
- High Density Polyethene
- Used for pipes, bowls, milk crates and buckets.
- Trade name: polythene.
- Thermoplastics
- Thermoplastics
- Polystyrene (PS)
- High density PS are good for insulation and is hard and brittle.
- Vacuum Forming
- Where a sheet of plastic is heated up and pressed against a mould to produce an impression of that shape.
- Most popular material to use is polystyrene because it's cheap and easy to form.
- 3D Printing
- Gives designers and product development teams rapid prototyping technology.
- CAD software sends 3D image to 3D printer and the item is 'printed' layer by layer in a range of materials.
- Concept models can be produced easily and quickly and 3D printers offer: speed, low cost and ease of use printing process.

- Laser Cutting
- Where a piece of material is cut using a laser beam - a powerful wattage laser beam produced inside the machine.
- A series of mirrors direct the laser beam vertically up and down onto the material to be cut (called 'flying optics').
- As the laser beam hits the material, the intense heat vaporises it - leaving a polished surface.
- A series of mirrors direct the laser beam vertically up and down onto the material to be cut (called 'flying optics').
- Injection Moulding
- Where plastics can be injected into a mould to make a product shape.
- Process:
- 1. Plastic powder or granules are fed from the hopper into a hollow steel barrel.
- Process:
- 2. Heaters melt the plastic as screw moves it along towards the mould.
- 3. Once sufficient melted plastic has been accumulated, the hydraulic system forces the plastic into the mould.
- 4. Pressure is maintained on the mould, until it has cooled enough to be released.
