Ntf Blow Moulding

Blow moulding a manufacturing process to produce hollow plastic parts. The manufacturing process in blow moulding begins with melting of the plastic and forming it into a parison or a preform.The parison is then clinched into a mould and air is blown into it. The air pressure causes the plastic to expand and match the mould. After the plastic has cooled and hardened, the mould is opened and part ejected.
