ICMA San Giorgio S.p.A.

ICMA manufacturing range is inclusive of the standard twin-screw corotating extruders (V class) and the high-torque version (HT and HP class) and to covers a very wide range of plastic compounded products, ranging from techno-polymers to bio-polymers.

The extruders, entirely designed and manufactured by ICMA, are supplied with modular structure gear-boxes adaptable to the working conditions of the various versions (low-speed, high-speed, high-torque and high-volume).

TECHNICAL FEATURES OF THE EXTRUDERS
- Modular design for screw and barrel
- Built-in water circuit for barrel cooling
- Intermeshing screw geometry
- Energy-saving heating system
- Updated electronic control devices

PERFORMANCE
- Highly flexible modular system
- Energy saving, low specific-energy consumption
- High intake capacity of feed screws
- Fast recipe or colour change due to self-wiping geometry
- High plasticisation capacity
- Calibrated control of melt temperature
- High homogenising/distributive extrusion capacity
- High dispersive extrusion capacity
- Fine-tuning of residence time-shear/elongation stresses parameters balance
- High venting efficiency due to the large surfaces and to the system’s modularity

Wear-resistant steel and removable liners can be applied according to the type of process.

We supply extruders and complete systems with all components including turn-key solutions.
For the STANDARD COMPOUNDING we offer dedicated high-performance systems to reduce production costs.

For customers devoted to SPECIALTY COMPOUNDING, we offer solutions with high technologal control and extraordinary versatility.

Overall ICMA serves the Compounding and Masterbatch industry with state-of-the-art technology solutions to cover the widest range of formulation.

The co-rotating technology delivered by ICMA is appropriate when:

— There is a need to process materials that are hardly recyclable with traditional technologies
— You want to create a material with higher specification to replace virgin materials in technical applications
— You need a very high production capacity. In these cases, it becomes more and more frequently the case of companies normally using single-screw extruders for the recycling of materials from post-consumer, that when it becomes necessary to expand their business, they choose to almost double their production capacity by replacing the existing single-screw extruders with the same number of twin-screw co-rotating ones.

Another advantage, not negligible considering the trend of the energy costs, is represented by the very high energy efficiency that the co-rotating technology guarantees.

Notwithstanding all these assessments, is still difficult to "sell" these benefits when you have to extrude a seemingly simple product: However it should be considered that only the co-rotating technology has the unique opportunity to engineering the recycled materials by adding fillers or reinforcements thus giving a much larger and profitable opportunity to the market.
