Blow moulding plastics is a manufacturing process that uses air blown into a mould cavity to create a hollow component. It is commonly used to make parts for the construction, industrial, automotive, medical, and packaging sectors, amongst others. It works in a similar way to standard extrusion, using plastic pellets that are softened and pushed into the mould cavity to form the required shape. The difference is the addition of compressed air that forces the plastic outwards and produces the hollowed-out effect.
At TH Plastics we specialise in a wide range of plastic ancillary equipment for the blow moulding industry.
