Extrusion International 3-2022

54 Extrusion International 3/2022 Periphery S tips, burns, greying, and black specks cannot be avoided in the productionofcompoundsandpellets. Even though the number of defects is usually low, these small defects can have a major negative impact on the production of particularly cost-inten- sive or sensitive components. Rejects are the result, which is annoying and expensive, and highly unecological, just like an unnecessary waste of en- ergy and personnel costs. Sortco offers its sorting service to prevent such problems. The order size can vary from 1 tonne to sev- eral 100 tonnes. "We can sort av- erage goods with high contamina- tion rates as well as reliably detect and discharge small amounts of contamination in granulate batch- es," Lars Ruttmann points to a wide range of applications. After all, he relies on state-of-the- art detection and sorting technology at his new company location in Nie- derzissen. In addition to mechanical separation systems such as dust col- lectors and metal separators, vari- ous optoelectronic sorting systems ensure the best results. Colour devia- tions from a size of 50 x 50 µm can be detected and removed in any free-flowing granulate. The result is a virtually defect-free granulate that the customer can choose to receive back in sacks, octabins, or big bags and use in any application without any problems. Many customers, mostly interna- tional plastics producers and com- pounders have long since placed their trust in Sortco's expertise and can thus in turn provide their customers, the plastics processors, with the highest degree of safety for component production. A clas- sic win-win situation that is both economical and resource-saving. SORTCO GmbH & Co. KG Schnackenburgallee 179, 22525 Hamburg, Germany sortco.de Flawless Granulates for the Highest Optical Requirements Around 12,000 tonnes per year of sorted granulates leave the new granulate sorting centre of SORTCO in Niederzissen/Germany. "With innovative mechanical and optoelectronic sorting systems, we guarantee the highest granulate purities and our special know-how enables us to meet the highest quality requirements of our clients" introduces managing director Lars Ruttmann the service of his company, which has its headquarters in Hamburg. "The goal is the safe and reliable sorting out of unavoidable impurities that could lead to machine downtime, expensive repairs of tools and hot runner systems and cause complaints and image damage during subsequent processing." Lars Ruttmann, General Manager of SORTCO GmbH & Co. KG: "We can sort average goods with high contamination rates as well as reliably detect and discharge small amounts of contamination in granulate batches."

The laboratory testing system is far superior to the human eye and immediately identifies all colour deviations from a size of 50 µm On the right, a sample of the contaminated granulate before the sorting process; on the left, the same material after the sorting process
