cooling mixer combines the functions of a highly efficient static mixer with those of a heat exchanger in one component. A heat transfer fluid flows through the mixing elements inside the mixer leading to a very effective heat exchange in the smallest installation space. The latest applications of this technology include increasing the through- put of a PET sheet extrusion line and enabling the use of an underwater pelletising system for sticky, low-viscosity hot melts. “The line speed of a PET sheet line is limited by the temperature of the melt after leaving the die, as well as by the power of the extruder,” the company said. “If the temperature is too high, the surface becomes uneven or the cooling track before winding is too short. Neither of these issues can be easily resolved. The P1 cooling mixer enables the temperature of the melt to be reduced to a mini- mum before the die, ensuring a perfect sheet even at a higher output. The latest tests show an increase in output of up to 20% with the same quality.” Producing pellets with hot melts that have a low melting point and low viscosity can also be described as challenging. A simplified method involves using a melt pump after the reactor to cool the hot melt in a P1 cooler. This allows the material can be cooled by 60°C or more. Due to the mixing structure of the P1, the material is homogenised during this stage, resulting in a high-performance hot melt in one step.
New collaborations More companies are seeing the value in collabora- tions. Periplast, a Portuguese outfit with over 40 years of experience in extrusion equipment, recent- ly announced a strategic partnership with Extruder Experts, a German company which manufactures components and spare parts for co-rotating twin screw extruders. All its components are compatible with leading brands and it uses materials carefully

Xaloy has acquired Ultimate Twin Screws (UTS), based in Ontario, Canada, and said it is combining its strengths with UTS’s specialised knowledge in twin screw design and production to form Xaloy Canada Corporation. “This acquisition reinforces our commitment to serving customers with the broadest and most innovative solutions in the industry,” said Andrew Brickman, chairman of Xaloy. “By adding twin screws to our portfolio, we strengthen our ability to partner with customers in solving their toughest processing challenges.” In the constant quest to improve efficiency, many companies are exploring solutions driven by artificial intelligence (AI). Real-time monitoring has become more sophisticated, with sensors accurate- ly tracking temperature, shear, pressure, and more, while digital controls allow for dynamic adjustment of process parameters to maintain consistency and reduce scrap. NEC and Maruki Sangyo recently conducted an AI-assisted demonstration experi- ment to improve material development. By entering the desired characteristics and colour, the system presents the most appropriate proposal according to the fluctuating inventory of plastic waste. In the demonstration test, it was confirmed that the compounding and colour mixing plans presented by the system were accurate enough for practical use, and that it can reduce the time required to determine pigment combinations by up to 50%.
