Blow Molding

Posted by: Mu Ju 2019-06-07 Comments Off on Blow Molding


Blow Molding is a highly developed molding technology developed back in the late 1800’s to produce celluloid baby rattles. It is best suited for basically hollow parts (such as plastic bottles) with uniform wall thicknesses, where the outside shape is a major consideration.

The first polyethylene bottle was manufactured using the blow molding process in December of 1942. This was the real beginning of a huge industry which currently produces 30 to 40 billion plastic bottles per year in the U.S. alone.
