APPLICATIONS

Extrusion Blow Molding (EBM) is the oldest of the various various blow molding processes. It really came into being in the 1930s when a Mr. Ferngren developed plastic bottles made from cellulose acetate in an automatic process. This technology was later used by the PLAX Corporation in the US, a company that developed EBM as well as other plastics technologies. Glass bottle manufacturers saw the potential  potential potential potential   in plastics starting in the 1950s. Owens-Illinois had purchased part of Plax and used it to develop their own style of machines and Wheaton started the production of injection blow machines.bottles-containers-slide

The development in Europe progressed in isolation from the US industry because of the Second World War. But by the 1950s Germans had come up with automatic blow molding machines that were also exported to the US. Reinhold Hagen, Johann Fischer, and Gottfried and Horst Mehnert founded EBM machine manufacturing companies that became Krupp Kautex, Fischer, and Bekum Maschinenfabriken respectively. While Fische no longer exists the other two companies still dominate the global market for EBM machines although it seems they have crossed their zenith.zenith zenith

EBM is a single-stage process; the process starts with resin pellets or powder and delivers containers ready to be packaged. While a core and a cavity form an injection molded part, EBM only needs a cavity into which a suitable device blows a hollow plastic tube called a parison. An extruder forms part of every EBM machine melting the resin and delivering it to a die head. The solid stream of plastic from the extruder is transformed into the hollow parison with a variety of head configurations. The main advantage of the process is its ultimate flexibility. Machines are in production today that make 2 oz. eye droppers in 1 to 24 or 72 cavities and others producing 55 gallon drums or even bigger Intermediate Bulk Containers (IBC). Companies developed unique machines adapted for the various applications and generally we can divide the market into the packaging and the industrial sector.
