What it does
The injection Blow moulding (IBM) process produces
billions of plastic containers each year. Ranging in size from 1 ml
to 2 liters, these containers meet exacting standards of consistent
weight, volume and tolerance, and are popular around the world for
a myriad of applications from pharmaceuticals to toiletries to automotive
to household use.
What it costs
Compare an injection Blow moulding machine to a similarly priced extrusion
Blow moulding machine: With IBM it is possible to produce more bottles
per cycle and more bottles per hour without deflashing, trimming,
re-granulation and re-mixing of scrap, at a constant weight and with
injection moulding tolerances. In fact injection Blow moulding does
not produce a significant amount of scrap polymer, many companies
are using virgin materials continuously.
How it works
The heart of the injection Blow moulding process
is a triangular rotary table, which indexes in 120° steps. Core
rods mounted on the face of the table form the inside of the hot parison
(or preform) that is later blown into the finished container.

| Station
1: |
This
is the preform mould. Here, molten material is injected under
low pressure into the mould cavity, where it forms a parison
around the core rod. At this stage, the neck section is injection
moulded to close tolerances. After suitable conditioning, the
moulds open and the parison is transferred on the core rod to... |
| Station
2: |
This
is where the blow takes place. The cavity of the mould defines
the shape and finish of the container. The parison is blown
with air fed internally through the core rod. As the blown plastic
contacts the cold blow mould, the final moulding is produced.
The mould opens and the finished bottle is transferred on the
core rod to... |
| Station
3: |
Here,
the bottle is stripped from the core rod for packing or filling. |
Why Jomar & IBM
 |
The
Jomar Vertical Plastifier uses typically 1/3rd less energy than
a horizontal reciprocation screw. |
|
It
is possible to make from 1 - 32 bottles per cycle. Cycles start
at about 9 seconds for 10ml bottles, up to 20 seconds for technical
parts and the larger containers. |
|
Many standard materials can be moulded: HDPE, LDPE, PP, PS, MIPS, PVC, PET, PC, Barex, K Resin, Santoprene,
PU etc. Some materials require drying, fan cooled barrels, screw changes, heated core rods etc.

Machines range from Model 15 - 175 with a vertical plastifier. The
M65 - M175 can be equipped with a horizontal, microprocessor-controlled reciprocating plastifier. |
