Clues

  • 1. Plastic granules are placed in hopper. 2. Archimedean screw rotates forcing the pastic to the heaters where it melts. 3. hydraulic ram forcers softened polymer theough into the mould. 4. left to cool, mould opened. (9, 8)
  • 1. slug power material is placed between the mould. 2. the mould is heated. 3. The mould is closed onto the preform and the pressure used will forceout any excess material. 4. the mould is opened and the product can be ejected (11, 8)
  • Can be made tough and hard or soft and flexible, solvent resistant, age hardens (4, 5, 8)
  • Copper electrodes come together, to clamp material in place. Circuit completed, electricity flows. Heat generated, to fuse material together. Electrodes removed, and ‘nugget’ of molten material solidifies forming the joint (4, 7, 7)
  • East to apply, relatively cheap, east to clean, comes in a variety of colours (8, 10)
  • In this process the molten metal is poured into the dies through runners (7, 3, 7)
  • Metal alloys specially developed to remember their shape under specific conditions (5, 6, 6, 3)
  • More flexible, soften when heated, can be reshaped (13, 7)
  • Rigid, hard, good strength, brittle, heat resistance, good electrical insulator, used for electrial fittings and adhesives - thermosets (4, 12, 2)
  • Work chemically cleaned. Heated to a suitable temperature. Fluxed. Molten zinc. Aluminium added for bright finish. Work dipped. Work cooled. Precautions against heat/PPE. Ventilation (11, 7)
