( Mechanical engineering : Manufacturing and assembly )
Blow molding is a process in which hollow plastic objects, such as drinks bottles, are formed.
The basic principle of blow molding is to inflate a softened thermoplastic hollow preform against the cooled surface
of a closed mold, where the material solidifies into a hollow product.
Blow molding is a process for forming plastic objects in which plastic is melted, put in a mold,
and then shaped by having compressed air blown into it.
