Experimental bottle blowing machine

Experimental bottle blowing machineBlow molding is the process of extruding and melting resin, then pushing out a tubular billet through a mold head into a blow molding mold. Compressed air is used to inflate and cool the billet, resulting in a product with the same shape as the mold cavity.
