Jomar's ISBM (injection stretch blow moulding) series for the production
of bi-axially oriented containers is the logical offshoot of the
Jomar injection blow technology. It is the first injection stretch
Blow moulding machine that utilizes only two stations to perform
the stretch blowing process.
Stretch runs more economically:
Jomar*s two-station ISBM machines require less tooling than three-station
rotaries with comparable cavities. Injection takes place at station
one. Following a 180? rotation to station two, bottles are stretched
using rods and blown using high pressure air, then ejected through
the bottom of the blow moulds. This eliminates the need for an eject
station and the associated tooling.
Stretch improves clarity and strength:
For clearer bottles, process them on a Jomar injection stretch machine.
The ISBM series strengthens nearly any container design, specifically
on longitudinal and hoop strength.

Stretch permits faster tooling changes:
The ISBM design is one of quick- change artistry. Preform injection
moulds release with just four bolts a Jomar exclusive. Core rods
and stretch rods release with the pull of a pin. Preform moulds slide
out on a steel shelf for easy removal. Preform tools change out
faster than conventional moulds, because a unique design allowing
installation without the need for realignment. Blow moulds release
with only four bolts and quick disconnect water lines.
Markets:
The Jomar ISBM35 is ideally suited for the manufacture of spirit
miniatures, hotel samplers and toiletry bottles up to 250ml.
Technical:
The preforms are quickly cooled in station 1, only the internal
and external skins are cooled to below 70?C. This allows the removal
of the core rod from the preform and the preform from the preform
mould. As the machine is cycling between 10-12 seconds overall for
typical products, the preform quickly reheats during transfer and
the 2-4 second blow delay in the blow station. Stretching, blowing
and ejection typically takes 3-5 seconds in station 2 after the
blow delay.
