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

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.
Icma San Giorgio SPA (Milan, Italy) has delivered in April a complete extrusion system to a major European pharma group. The new line extrudes several types of TPE foil for pharma applications. Gravimetric dosing units, a high-efficient co-rotating extruder ICMA MCM 60 and downstream equipment of a three-roll calender and fully automated winding unit make the line. ICMAs turn-key system encompasses complete project engineering with several customized features very tied to customers requirements, including solutions for assuring maximum cleaning of the entire process line commanded by critical pharma applications. The line also incorporates several high tech digital solutions and sensor devices applied to key parts such as the calendaring movements and thickness control, to grant maximum accuracy during extrusion and the highest standard of safety for the operators. “This is an excellent example of ICMAs ability to tackle turn-key project from idea to factory start-up where a high level of customized engineering and industrial reliable execution are key factors to succeed. Icmas capability to combine customization and maximum performance is unique in our industry” said Giorgio Colombo, Managing Director of Icma San Giorgio. The line was erected and tested at ICMAs premises prior to installation at the customers site.
ICMA SAN GIORGIO, founded in 1945 and part of an industrial Group with more than 100 years of history, is a well established Italian manufacturer of co-rotating extruders and turn-key compounding and extrusion lines for a broad range of applications in industries such as plastic & rubber, recycling, biopolimers, pharma, masterbatch, natural fiber composites, chemicals & petrochemicals and food. With 10.000 sq mt facility made by workshops, laboratory and assembly areas, ICMA provides customer and partners with a solid and very modern industrial platform. Its egineering capabilities also deliver customized solutions and plants at the highest level of technology and performance. ICMA is a company where people listen and react quickly and where things happen in a Win-Win model. ICMA's lines, typicall based on co-rotating extruders or in combination with single extruders, are unique for process design, material and steel selection, construction protocols and precise machining and assembly.
ICMA is a "Seal of Excelence" company from the European Community and a member of the World Alliance for Efficient Solutions.
