The new DynaShape technology responds to changes in feed material shape and bulk density by automatically adjusting the machine to get the best possible results from the polymer. During exhaustive test runs that simulated different stages of production, including changes in the input material, Pure Loop clocked an increase in productivity of up to ten percent.
The integrated ISEC shredder-extruder combination with patented double feed ram system and conical transition to the extruder reliably processes clumps, guillotined rolls of film, film shreds, glass fibre-reinforced plastics and fibres into high-quality recycled pellets. Previously, an experienced technician was often needed to optimise the relevant machine parameters. Now, DynaShape carries out this task automatically, ensuring that the machine operates consistently at maximum potential in all applications. This significantly reduces the time and labour required to get the best output.
The core of DynaShape is based on the interaction of two components. The proven double feed ram system, which now dynamically adjusts its speed to the rotor load, while the hydraulically adjustable intake apertures adjust automatically – instead of manually as before. Throughput is increased as a result, and so is the quality of the melt. Thanks to the consistent melt pressure and optimum extruder screw filling level, there is no oxidative degradation of the melt. What is more, the temperature of the melt can be trimmed automatically on a case-by-case basis by setting a maximum temperature for each polymer. In contrast to manual operation, DynaShape reacts immediately to increases in temperature to make sure that the specified limit value is not exceeded.
Another practical feature is that the intelligent DynaShape settings can be saved as a recipe. This means that the next time it is started up, the machine operates immediately with the optimum setting, further reducing the time required for manual intervention.
