PLASTICS: - Coggle Diagram

- - - - 1: We put thermoplastic; 2: We aplly pressure by means of a screw; 3: We cool the shaped material slowly; 4: We collect the pieces of plastic through a feeder system.
  - - - 1: We put thermoplastic into a mould; 2:We then use a heater to heat the mould and soften the plastic; 3: We extract the air below the sheet; 4: We leave the mould to cool, then remove the object
  - - - Injection
        
        It has two stages: 1:We inject melted thermoplastic into a mould; 2: When the material has cooled and solidified, we extract it from the mould
      - Compression
        
        It has four stages: 1: We put thermostable plastic in a base; 2: The outer part of the cavity mould is closed; 3: The plastic adapts to the shape of the cavity; 4: We take the object
      - Blow moulding
        
        It has three stages: 1: We put a tubular-shaped piece of plastic into a hollow mould which the same shape of the object we will make; 2: We close the mould and blow pressurised air into it; 3: When the object is cold, we remove it from the mould.
- - - - Mechanical fasteners: Nut and bolt; Standard screw; And double ended screw
    - - Adhesives: Joining two surfaces permanently
      - Soldering: Joining thermoplastis using heat and pressure.
