  Blow moulding is a manufacturing process used to produce hollow plastic parts by inflating a heated plastic tube inside a mould cavity. It's similar to blowing up a balloon inside a shaped container to take the form of that container.
  
  1. Extrusion Blow Moulding (EBM)
  
  A molten tube of plastic is extruded vertically into a mould.
  The mould closes around the tube, and air is blown in.
  Used for: Milk bottles, shampoo bottles, toys.
  
  2. Injection Blow Moulding (IBM)
  
  A preform is created using injection moulding.
  The preform is then reheated, placed into a mould, and blown.
  Used for: Smaller containers, like pharmaceutical bottles.
  
  3. Stretch Blow Moulding (SBM)
  
  A preform is both stretched and blown to form the final product.
  Offers high clarity and strength.
  Common in: PET bottles for soft drinks and water.
