Shuttle blow moluding
equipment offers the following advantages
Relative
low cost compared to other extrusion blow moulding machinery
Capable of producing
high-quality "calibrated neck" finish with blow
pins.
In-machine trimming
- finished bottles exit the machine.
Capable of producing
bottles of all shapes - including handleware.
Coextrusion capability,
with up to six layers of plastic.
Shuttle machines have
some limitations.
Not cost effective for extremely high volumes.
Reduced bottle
weight consistency compared to rotary wheel machinery,
due to inevitable variations among the number of unique
parisons that must be extruded in shuttle equipment.
Cycle time disadvantage
when compared to reciprocating screw machines and rotary
wheel machines, particularly when producing lightweight
containers
