Since plastics are so diverse due to their properties and applications and each market has its own requirements, the sorting requirements are also very individual. The requirements in the XLPE market differ significantly from standard plastics. It is not just a matter of identifying different materials, cross-contamination or coarse impurities. Find out what additional requirements exist and how the innovative inspection and sorting system, PURITY SCANNER ADVANCED from SIKORA, meets these requirements.

In addition to the targeted detection and sorting out of the smallest black specks and yellowing, the seamless detection and sorting out of the smallest metal particles is also indispensable. Furthermore, it is essential that the material transport and the type of sorting itself do not introduce any additional external contamination into the material flow.
Another criterion is the space in the production environment. The material flow of XLPE runs by gravity directly from the dust removal on one floor to the sorting on the next floor. Space is limited and a cost factor here. Accordingly, the sorting of optical and metallic impurities should be carried out directly on one floor.
Furthermore, the sorting should be carried out in a way that as little as possible of the good, i.e. clean material, is sorted out. Exactly these requirements were brought to the SIKORA development team by XLPE experts from the industry more than ten years ago. Meanwhile, the fourth generation of the PURITY SCANNER ADVANCED is used by numerous customers worldwide.
Experts in the XLPE market are aware of the advantages of the PURITY SCANNER ADVANCED with regard to the precise sorting of the smallest impurities in the range of 25 µm as well as the sorting of metal particles of 50 µm in size in a single material pass. Likewise, the numerous users of the PURITY SCANNER ADVANCED know that only a material transport system with a stainless-steel channel will not bring any impurities with it and that a targeted blowing out with cleaned compressed air using an intelligent approach will cause the least possible ejection of clean material.
This further optimizes production processes, ensures the quality of the XLPE material and, thanks to reduced ejection, contributes to cost-efficient and sustainable production.
