Evolution of Blow Molding Machines

Blow molding is a manufacturing process by which a hollow plastic perform is placed inside a mold so that it forms the shape of the mold cavity in a blow molding machine. The technology is borrowed from the glass industry. Below are the stages how this technology has evolved: First Century BC: The air to blow hot material technology was initiated by Syrian glass workers in the first century BC. 1851: In the early 1851, S.T Armstrong found out that blow molding can be done with plastic too (in addition to glass). 1938: Blow molding became commercialized in 1938. Introduced by Ferngren and Kopitke the machine was sold to the Hartford Empire Company for commercial use. HDPE: Then came the advanced version of the HDPE (high density polyethylene). 1977-1999: From 1977 to 1999, the soft drink industry went from zero plastic blow molded bottles to 10 billion per year. 3D: With the advancement in microprocessor technology and equipment, the introduction of the 3D blow molding came into existence. This was revolutionary for the plastic industry! 2016: In 2016, the global blow molded plastics market size was over 68.10 million tons! Today a blow molding renaissance is occurring with microcomputer control system that control various technical parameters required for accuracy and durability. This will serve a huge variety of industrial and technical applications. Source: https://www.monroemold.com/
