With a manufacturing facility in Italy and it's head office and main engineering/production/manufacturing line in New Jersy, Jomar is truly a global player in the blow moulding industry. Jomar produces machines for Injection Blow Moulding (IBM), Extrusion Blow Moulding (EBM) and Injection Stretch Blow Moulding (ISBM).
Jomar machines are installed and supported worldwide with localised support and documentation.
Jomar IBM Machines
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. Ask Jomar for this information and on processing engineering resins
- Machines range from Model 15 - 175 with a vertical plastifier. The M65 - M175 can be equipped with a horizontal, microprocessor-controlled reciprocating plastifier.
- Machines used in and around clean rooms for pharmaceutical production.
