14/12/2020 – Inspection and sorting of plastic pellets
Guarantee for visually and functionally perfect products
Black specks and color deviations often lead to increased scrap rates in the production of plastic injection molded parts, but also in the manufacture of profiles, cables and pipes. The same applies to metal inclusions in the pellets, which leave traces in the end product and the processing machines and cause costs.
