Discmania’s plastics have two histories. Before 2021 the main line was moulded by Innova: C-Line was Champion, S-Line was Star, D-Line was DX, with P-Line and G-Line as the Pro and GStar equivalents. Since 2021 Discmania moulds C, S, and D-Line in its own factory, and the classes haven’t moved.
The Evolution moulds are made by Latitude 64 in NEO, EXO, and GEO, and the Active range by Yikun. So one brand, three factories, and the plastic name tells you which.
