    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.
