Injection Blow Molding   Overview Injection blow molding is used for the Production of  hollow objects in large quantities.  The main applications are bottles, jars and other  containers.  The Injection blow molding process produces bottles of  superior visual and dimensional quality compared to  extrusion blow molding.  The process is ideal for both narrow and wide-mouthed  containers and produces them fully finished with no  flash.

Injection Blow Molding ( 3 Step Process) Injection  The injection blow molding machine is based on an extruder  barrel and screw assembly which melts the polymer.   The molten polymer is fed into a manifold where it is  injected through nozzles into a hollow, heated preform  mould.   The preform mould forms the external shape and is  clamped around a mandrel (the core rod) which forms the  internal shape of the preform.   The preform consists of a fully formed bottle/jar neck with a  thick tube of polymer attached, which will form the body.
