Continuous and Intermittent are two variations of Extrusion Blow
Molding. In Continuous Extrusion Blow Molding the parison is
extruded continuously and the individual parts are cut off by a
suitable knife. In Intermittent blow molding there are two
processes: straight intermittent is similar to injection molding
whereby the screw turns, then stops and pushes the melt out. With
the accumulator method, an accumulator gathers melted plastic and
when the previous mold has cooled and enough plastic has
accumulated, a rod pushes the melted plastic and forms the parison.
In this case the screw may turn continuously or intermittently.
With continuous extrusion the weight of the parison drags the
parison and makes calibrating the wall thickness difficult. The
accumulator head or reciprocating screw methods use hydraulic
systems to push the parison out quickly reducing the effect of the
weight and allowing precise control over the wall thickness by
adjusting the die gap with a parison programming device.

Examples of parts made by the EBM process include most polyethylene
hollow products, milk bottles, shampoo [[bottles]], automotive
ducting, watering cans and hollow industrial parts such as drums.
Advantages of blow molding include: low tool and die cost; fast
production rates; ability to mold complex part; Handles can be
incorporated in the design.
Disadvantages of blow molding include: limited to hollow parts, low
strength, to increase barrier properties multilayer parisons of
different materials are used thus not recyclable. To make wide neck
jars spin trimming is necessary
