4 Our quality continues to improve The direction of the technical staff is to build plants that can offer higher quality end product, increased production capacity, more energy conservation and a better cost for the customer. In recent years, our principal efforts have been concentrated on finding ways to increase production and develop a means for significant reduction of energy consumption. In particular, this last directive has helped us realize the ECOTRONIC system. When installed in the COMPAC lines it allows for an energy savings of up to 40%. New centrifuge that reduces the noise pollution. Insulation system on extruder increases energy savings ECOTRONIC system reduces energy consumption by up to 40% and no longer uses water for precision temperature control.

Production quality has improved across all GM lines thanks to the new testing capabilities. The most important result is, after all, the quality of the final granule.

On most recycled materials with Gamma Meccanica lines the rheological curves overlap almost perfectly, demonstrating the efficiency of existing plants.

5 + More energy savings + Increased production capacity + Higher quality end-product + Better service Today, more than ever, Gamma Meccanica is better able to give customers the most comprehensive plant design specific to their production requirements. This is possible with the addition of a new laboratory pilot plant being used to perform tests on customer supplied materials. Production quality has improved across all GM lines thanks to the new testing capabilities. The most important result is, after all, the quality of the final granule. Tests show the nearly total absence of deterioration of a material after the process of recycling. On most recycled materials with Gamma Meccanica lines the rheological curves overlap almost perfectly, demonstrating the efficiency of existing plants. It is also possible to verify the deterioration and current state of the material prior to processing, and advise the customer what to add to improve the quality of the product during recycling. Adding value, or Upcycling is what we focus on for the customer. The table below indicates results achieved for various types of materials. Production has increased thanks to the improvements made to the plants.

12 Lines for particular productions Lines for PET The lines for the PET recycling are generally composed of conveyor belt, cutter-compactor, extruder, screen changer and pelletizer. The most important aspect when these materials are reprocessed is the necessity to limit the fall of the value of intrinsic viscosity (IV). This value determines the mechanical performances that the material can have. The lines that Gamma Meccanica designs allow for minimal to no loss in IV for some of the worst case materials that have high residual moisture These lines are designed for the regeneration of PA and other hygroscopic materials as well. This type of line is available in the models GM65, GM90, GM105, GM125, GM160, GM180, GM210 depending on the production capacity.

13 GM Tandem line for the recycling of heavily printed, high humidity and contaminated materials The tandem line has been designed for the recycling of materials very printed, or with humidity up to 10-15% and heavily contaminated. The plant is composed of a COMPAC feeding technology and two extruders placed in tandem to one another. The effectiveness of the plant is guaranteed by an innovative and patented degassing system. One main benefit of the line is the degassing unit that has a very high efficiency to treat materials with over 100% of print. The gases or the vapors that are formed from the melted material mixed inside the primary extruder are eliminated by the extraction force created by the vacuum. On the secondary extruder an additional degassing system can be installed to expel possible residual gases. Two screen changers can be connected: one after the primary extruder, that expels the contaminating element of greater size and the other after the secondary one that allows the elimination of particles from μm. Unit for the hard vacuum installed on Tandem lines. GM lines for the recycling of bio-polymers Gamma Meccanica has since the early 90 s begun a collaboration with companies that produce biodegradable materials. In using the experience and collaboration of the sector experts Gamma Meccanica has been able to produce advanced recycling plants for these materials. A meaningful experience we have is with recycling of PLA, a material that if it isn t regenerated in correct way, isn t suitable for re-use. For this purpose Gamma Meccanica has the experience required for this type of application getting excellent results that have fully satisfied the demands of our customers. ioplastic RECYCLING LINES 13

Extruders The extruder is the fundamental part of any regeneration system, composed of the cylinder, the screw, the variable speed electric motor and the speed reduction gear.

14 Extruders The extruder is the fundamental part of any regeneration system, composed of the cylinder, the screw, the variable speed electric motor and the speed reduction gear. The diameter and the pitch of the screw change depending on the type of material to regenerate. The extruder can be equipped with vents and degassing systems to extract the gases produced during the melting of the plastic, avoiding the beginning of defects in the granule such as gas or air bubbles. In our standard design the vents are placed side by side to allow the cleaning from the material without interrupting the vacuum. It is possible to install a variety of dosing systems, for example one placed in around the middle of the length of the extruder to introduce directly in the melt material. This solution yields similar results to that of a twin screw extruder. EXTRUDER Cutting Systems Water ring pelletizer TDA The water ring pelletizer TDA has been conceived with an innovative design that allows an operator a fast start/stop sequence and a rapid material change. It can be installed on lines suited to work most plastics (PE, PP, PS, ABS, MASTER, COMPOUN- DING and other). It is compatible with most if not all the models of extruders currently proposed on the market. The Water Ring Pelletizers TDA are available in these sizes: 2.0, 3.4, 4.0, 5.0,
